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

 dots scattered over their surface (tlie remaius of sebaceous glands). 

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

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

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

 efficient apparatus for burrovving. The tail oifers many difFerenees 

 from that of the other species of the genus Perameles. l'he basai 

 fourth is clothed with hairs about the šame 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 -vybite, AVitb a ridge of long 

 Avhite stiiF 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 ■svhich is 

 1 inch 3 lines. 



" The skuU is perfect, but the statė of the skin was such as totally 

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

 particulai's concerning the bones of the face. The interparietal and 

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

 is Inrge, and its shape that of a flattened ovoid. The tympanum wa8 

 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 s])ace of į an inch. The lower-jaw is slender, with a 

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

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

 ąuadrangular ; 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 šame distance from each other 

 as the t\vo anterior. Posterior to the Lncisors is a space about 5 lines 

 in width, for the reception of the inferior canines. The canines are 

 well developed : another space inter\enes betvveen them and the falše 

 molars, which latter are aU rather widely separated, of a conical 

 shape, and have a small tubercle anterior to the body of the tooth. 



" The molars oiPerameles, as figured by M. F. Cuvier in his 'Dejits 

 des Manuniferes,' consist of two prisms lixed to a slightly curved 

 base, Avith the concavity towards the inside of the jaw ; but in 

 this species the molars are ąuadrangular, having had but two sets 

 of tubercles, and in the preseut specimen these teeth are worn 

 dovm and present a sąuare smface, inclosed by enamel, having a 

 band of the šame running transversely across the middle of the tooth. 

 The two lašt molars of the upper ja\v approximate so closely, as to 

 reąuire careful examinatiou to detect the line of separation. The 

 teeth of the lo\ver jaw, except in number and in the circumstance bf 

 all the incisors forming a continuous series, do not differ from those 

 of the upper. When the jaws are closed, the posterior molars of the 

 ui)per and lo\ver ja\vs are in contact.

 these animals are found beyond the mountains of Swan River, in
