Hub. North-west coast of Australia. 



This species of Petrogule is remarkable for its small size, the gene- 

 ral pale colouring and the bright rusty tint of the upper parts of the 

 body ; these parts are freely pencilled with whitish and with brown ; 

 the sides of the neck and body are of a delicate yellowish hue, or 

 might be described as very pale rust, and this is the prevailing hue 

 of the head, which is nearly of a uniform tint ; but is white, or 

 nearly so, on the sides of the muzzle at the tip, and there is a trace 

 of the usual white mark on the cheeks ; above the eye is a spot of a 

 pale rust-colour, and an indistinct brownish mark running towards 

 the nostrils from the front of the eye ; the ears are clothed within 

 with white hair ; externally they are of the same palish rusty yellow- 

 ish hue as the upper surface of the head ; the chin, throat and whole 

 under parts are white, with a faint yellowish rusty tint ; the outer side 

 of the hinder legs is of a brighter tint than the sides of the body, but 

 less red than the back ; the feet are of a very pale brownish colour, 

 freely pencilled with dirty white; a small space at the base of 

 the tail is covered with fur of the same texture and colour as that 

 of the body ; beyond this the hairs of the tail are harsh, at first 

 about half an inch or rather more in length, but becoming gradually 

 longer towards the apex, where they are more than an inch long ; 

 these hairs are of a yellowish white colour, but the apical third of 

 each hair is black. This species was brought to England by Lieut. 

 Emer\^ of H.M.S. Beagle, and is now in the British Museum. 



The second species belongs to the section or genus Hahnaturus, 

 and received from Mr. Gould the specific name Binoe, in honour of 

 Benjamin Bynoe, Esq., to whom science is indebted for the discovery 

 of many new and interesting objects in zoology. It is nearly allied 

 to Halm, ag'dis, but in size is about equal to Halm. Thetis. The fur 

 is harsh and adpressed, and for the most part of a very pale brownish 

 yellow tint ; the back, however, is freely pencilled with black, the 

 longer hairs having the exposed portion of this colour ; a slight 

 brownish grey hue is observable next the skin in the hairs of the back, 

 but they are nearly uniform throughout their length, if we except a 

 small black point to the shorter hairs, and the exposed black portion 

 of the longer hairs ; the sides of the body and the limbs are of a paler 

 hue, and are not pencilled with black ; the abdomen may be de- 

 scribed as of a dirty yellowish white colour ; the tail is very nearly 

 uniform in tint with the body, but a small portion at the apex is 

 covered with brownish black hairs ; the upper surface of the head 

 is slightly tinted with brownish, and a mark of this colour runs from 

 the eye to the tip of the snout on either side ; adjoining this mark 

 below is a pale mark ; the ears have yellowish white hairs on the 

 inner side, and rusty yellow hairs on the outer side ; but along the 

 anterior margin, and at the tip externally, the ears are black. The 

 principal characters may be thus expressed : —
