are aituatod. The wout is covered with small huuimc of various 

 form* ; the rat of the head with muall suborbicular carinated scales, 

 The mouth ut large, the jaw* nearly of equal length. The teeth 

 close tet, regular, small, reflex ; a marginal and two palatal row* in 

 the upper jaw. The eye* vortical, uuall, orbicular, protuberant, each 



situated in the centre of a 

 remarkable circle of small 

 triangular laminic. The nos- 

 tril* very small, vertical, near 

 to each other, and close to the 

 apex of the rostrum. 



"The trunk thick, round, 

 covered with large carinated, 

 broad-oval, imbricate scales. 

 The length 3 feet 44 inches; 

 thickness near the head about 

 3 inches ; the middle of the 

 trunk 44 inches. The tail 

 measures only 8 inches, is a 

 little compressed, tapers 

 moderately, and terminates in 

 on obtuse point. 



" Part of the head is almost 

 black; the colour of the trunk 

 and tail a very dark gray; 

 the throat, belly, and under 

 port of the toil ore of a dusky 

 yellow ; but the colour of the 

 scuta seemed to have been 

 changed by the spirits."

 that his specimen from which

CKRCIS, a genus of plants belonging to the natural order Lcgumi- 

 nottt. O. tili'iututrum, the Judas-Tree, so called from the tradition 

 that it was upon a plant of it, near Jerusalem, that the betrayer of 

 our Sxviour hanged himself, is a leguminous tree common on the 

 shores of Asia Minor and in oil the East. Dr. Walsh speaks of it OH 

 abounding in the Levant at the present day, clothing the shores of 

 the Bosporus and the sides of Mount Libanus. It is very beautiful 

 in all its stages. Very early in spring flowers of a bright pale red 

 bunt out before any leaf appears, not only from every part of the 

 branches but from the trunk, piercing the thick strong bark nearly 

 down to the root in a very remarkable manner, and it is for this 

 reason called Hed Bud. These buds are gathered and used with other 

 raw vegetables by the Greeks and Turks in salads, to which they 

 give an agreeable colour and taste. It is very common in England, 

 where it prove* quite hardy, but it does not flower well unless in a 

 very sheltered situation, or when trained to a wall. There is a pale 

 almost white-flowered variety, and also an American species (C. 

 Omtaiauu), but neither is worth cultivation.

i T.KEOP8IS, a genus of Bird* ertablished by Latham, and placed 

 by him (1802) among the Waders (Orallalora) ; and (in 1824) next 

 to the Swimmer* Palmipeda (Aiuera, Linn.). The characters of 

 this bird, which Mr. Bennett nay* ha* been observed by nearly all the 

 navigator* who had visited the south coast of Australia and it* 

 neighbouring islands from 1792 downwards, are as follows : 



Bill short, elevated, obtuse, covered by a broadly expanded cere, 

 except at the extremity, which is somewhat vaulted and truncated. 

 Nostrils Urge, situated about the middle of the bill, and open. Feet 

 with tarsi (shanks) longer than the middle toe, and bare of feathers 

 a little way above the knee* ; great toe articulated to the posterior 

 part of the tarsus ; anterior toes palmatod, and furnished with 

 membrane* deeply notched or cut out as it were so as to appear 

 scarcely to roach beyond the half of tli.-ir I'-n^th; nails long and 

 strong ; wing* ample ; wing-coverU nearly a* long a* the quills ; 

 flrt quill a little shorter than the succeeding ones. Tail feather* 

 sixteen. 



C. Nova J/nll.ii.- roopsis Goose, is about the size of the 



common goose and nearly of the same carriage, with the exc< , 

 of the length of the legs. Temminck gives the length at from 2J feet 

 to 3 feet. We select Mr. Bennett's description : " A broad patch on 

 the top of the head is of a dull white, and the rest of the plumage 

 of a dingy gray, deeper on the upper than on tin- i.n.l. r parts, having 

 the extremity of each of the feathers of the back margined with a 

 lighter bond, and most of the wing-coverts and secondary quill- 

 feathers marked with rounded dusky ajiota of from two to four lines 

 in diameter. On the feather* of the back and shoulders the spots 

 are much larger, assume an angular or semilunor form, and approach 

 more nearly the general colour of the plumage. The quill-feather* 

 both of the wings and tail ore dusky black throughout the greater 

 part of their extent The naked extremity of the bill is black ; the 

 broadly expanded cere of a light straw or lemon colour; tin- irides 

 light-hazel ; the naked part of the leg* reddish-orange ; and the toes, 

 together with their web and claws, and a streak passing for some 

 little distance up the fore part of the leg, block." 



Mr. Yarrell having examined one that died in the Zoological Gardens, 

 Regent's Park, states that its trunk was much shorter than that of 

 the true geese, and more triangular in it* shape. The pectoral muscles 

 were large and dark -coloured. The trachea was of large but nearly 

 uniform calibre, without convolution, and attached in its descent to 

 the right side of the neck, as in the heron and bittern. In the form 

 of its bone of divarication and bronchia 1 , it most resembled the 

 some part in the geese. The muscles of voice pairs; one 



pair attached to the shafts of the on fiircatorium, the other to the 

 inner lateral surface of the sternum. The lobes of the liver were of 

 huge size, morbidly dark in colour; their substance broke down 

 under the finger on the slightest pressure. The stomach, a true 

 >.-i/.: ml, was of small size as compared with the bulk of the bird. 

 The first duplicating of intestine was 6 inches in length, at the 

 returning portion of which the biliary and pancreatic ducts entered ; 

 from thence to the origin of the ctcca 4 feet 6 inches ; the caeca 

 9 inches each ; the colon and rectum together 5 inches ; the whole 

 length of the intestines was 7 feet 5 inches. The stomach and 

 intestinal viscera were loaded with fat. 



With regard to its habits Mr. Bennett says" It is true that the 

 limited opportunities that have occurred of observing it in a state of 

 nature have precluded the possibility of obtaining a complete history 

 of its habits and mode of life ; but the accounts furnished by various 

 writers lead directly to the inference that it resembles the wild geese 

 of the northern hemisphere as closely in these particulars as in 

 general conformation. We cannot state with certainty whether it is 

 equally migratory ; but Captain Flinders, who found it at one period 

 of the year so abundant on Goose Island as fully to justify the appel- 

 lation, adds that it was by no means so numerous at a different season, 

 and this fact necessarily implies at least a partial change of locality. 

 In its manners it appears that it is l>y no means so shy as our in irthern 

 geese, a circumstance which probably depends on the Uttls disturbance 

 that it has hitherto met with in its native haunts. Labillardiere tells 

 us that many of those first seen by him suffered themselves to be taken 

 with the hand ; but the rest becoming apprised of their danger sp 

 took to flight. Considerable numbers were taken by the crew of 

 Captain Flinders' s vessel, both at Lucky Bay and < ;1, by
