328 PROF. E. C. STIRLING ON NOTORYCTES TYPHLOPS. [June 2, 



4 mm., enJing very bluntly ; the fifth is very slightly shorter thau 

 the fourth, broad at the base (8 mm.), tapering rapidly to a blunt 

 point, the two together forming an outline rather like that of a 

 goose-mussel (Lepas). The nails of the third, second, and first 

 digits, very much smaller, form a series gradually diminishing iu 

 size in the order named, and constitute a second row on the inside 

 of the fourth and fifth, by which, as stated, they are completely 

 concealed from view. What corresponds to the palm is the cleft 

 between the two rows of digits. 



" The hind limbs are also short, with the soles turned outwards. 



Outline of Notoryctes typJilops. 



What appears to be the fifth (anterior) digit is very short, with a 

 short, broad, and strong nail ; the fourth is armed with a long 

 (7 mm.), narrow, curved, and sharp claw; while the claws of the 

 third, second, and first are broad, flat, rounded at their points, and 

 joined together by a membrane which extends nearly to their points. 

 On the sole there is a hard, elongated, horny tubercle crossing it 

 transversely. 



"The tail 2 cm. long, and 5 mm. wide at the insertion, tapers to 

 3 mm. and terminates in a knob-like tip. 



"About 15 mm. in front of the vent (? cloaca) there is a pouch in 

 the integument about 4 mm. wide, with the opening directed back- 

 wards and having a depth in a forward direction of from 4-5 mm. 

 The surface of this pouch is devoid of hair, but the bare area is 

 surrounded by thick fawn-coloured fur, with a slightly reddish tint; 

 it is possible, however, that this reddish tint is due wholly or in 

 part to some ferruginous-looking sand which is much mixed up 

 with the fur. The body generally, with the exception of the lower 

 two-thirds of the tail, which is bare, is covered with fur of a rather 

 lighter tint. 



" With regard to the internal parts, it is unfortunate that the 

 specimen came to us completely eviscerated and in a bad state of 

 preservation generally ; but in a small part of the lower bowel which 

 was left, remains of ants were found. The bowel terminates at a 

 wide vent (? cloaca), and I can find no trace of a separate genital 

 aperture, nor of such openings into the supposed cloaca. I have 

 not yet had time to examine with minuteness the skeleton, which
