 "The ears are long, broad, and ovate, having several semitransparent 

 dots scattered over their surface (the remains of sebaceous glands). 

 On the anterior extremity the nails are much elongated ; the second 

 and third are about ^th of an inch longer than the first ; they are 

 all flattened at the tips, thus furnishing the animal with a very 

 efficient apparatus for burrowing. The tail offers many differences 

 from that of the other species of the genus Perameles. The basal 

 fourth is clothed with hairs about the same length and colour as those 

 of the body. The middle half is black, the hairs on the upper part 

 being elongated ; the remaining part is white, with a ridge of long 

 white stiff hairs forming a crest. 



" The pouch in this specimen (a female) is large, and has 9 nipples 

 on its posterior surface ; one being placed in the centre, and the 

 remainder at equal distances form a circle, the diameter of which is 

 1 inch 3 lines. 



" The skull is perfect, but the state of the skin was such as totally 

 to prevent its removal, and the description is therefore defective in 

 particulars concerning the bones of the face. The interparietal and 

 occipital crests are clearly defined and large. The bulla of the ear 

 is large, and its shape that of a flattened ovoid. The tympanum was 

 entire, and on removing it the manubrium of the malleus was found 

 to be twice the length of its body. The zygomatic arch is imperfect 

 for about the space of \ an inch. The lower-jaw is slender, with a 

 salient process at its angle. Dent.: Prim. -J-, Can. j^, Mol. spur,

" The two front superior incisors are nearly a line apart, small, and 

 quadrangular ; a small space intervenes between these and the three 

 succeeding, which are larger, and placed in a continuous series. The 

 fourth and fifth incisors are about the same distance from each other 

 as the two anterior. Posterior to the incisors is a space about 5 lines
