The Cheilodactylus carmichaelis (Hist, des Poiss. v. 360) {Chceto- 

 don monodactylus, Carmichael, Linn. Trans, vol. xii. p. 500. pi. 24) 

 approaches aspersus in shape, in the length of its long pectoral rays, 

 and in the number of fin rays generally, but it is distinguished by 

 six short, broad dark bars on the back. The formula of its rays is 

 as follows ■.—Radii.— Br. 6 ; D, 17|24 ; A. 3|12 ; P. 9 et VI.j V. 1|5,

The Cheilodactylus fasciatus (Cuv. et Val. v. 357) of the Cape is 

 distinguished by four or five vertical dark bands and five transverse 

 lines on each lobe of the caudal. Its rays are stated to be : —

This fish inhabits the seas of Van Diemen's Land and the east 

 coast of New Holland, as well as King George's Sound. A full de- 

 scription of it is coiitained in the ' Zoological Transactions ' quoted 

 above. It has the highest spinous dorsal of any described species of 

 Cheilodactylus, and in the distribution of its black bands it bears a 

 considerable resemblance to Eques americanus. 



Mr. Neill gives a drawing of it (No. 24), and states that it is 

 known to the aborigines of King George's Sound by the name of 

 " Kuelvek." The natives spear it on sandy banks, but say that it is 

 rare. Its scales are smooth, and the second and third anal spines are 

 moderately long and equal to each other. The suboperculum is nar- 

 row, and together with the other opercular bones and cheek is scaly.

 spec. 



The aborigines of King George's Sound had no name for this spe- 

 cies, and no drawing of it was made by Mr. Neill. The only speci- 

 men of it obtained was speared by a native named Murrianne, and 

 measures 13 inches in length. It has a conical eminence on the pre- 

 frontal bone, Uke that existing in Ch. gibbosus ; its face is short, with 

 the profile ascending almost as much as in the species just named. 

 The length of the preorbitar is rather less than the diameter of the 

 orbit, the eye is placed midway between the gill-opening and mouth, 

 and the interoperculum is only about half as wide as the disk of the pre- 

 operculum. The cheek and all the pieces of the gill-cover are densely 

 scaly. The second of the simple pectoral rays is the longest and it 

 falls short of the anus, while only about one-third of its length pro- 

 jects beyond the membrane. The spinous part of the dorsal is arched 

 anteriorly. Its fifth and longest spine rather exceeds one-third of 

 the height of the body. The preceding ones are graduated to the 

 first, whose height is only a fifth part of the fifth one, but the de-
