Beriham, however, ib was stated that "the testes of the male are 

 like those of a cat," which would seem to indicate that they are 

 a prominent external feature. There is apparently a tunica 

 vaginalis, also an epididymis closely applied to the body of the 

 testis, from which the vas deferens runs a nearly straight course 

 to the point indicated in the description of the bladder ; both it 

 and the spermatic artery pass through a ring-like aperture in 

 the peritoneum lining the abdominal cavity. 



The kidneys are suboval, with smooth surface, and close to 

 them, on the inner side, lie the adrenals of considerable relative 

 size ; the course of the ureters is sufficiently shown in fig. 5, 

 and their termination in the bladder has already been described. 



On each side of the terminal part of the cloaca, lying embedded 

 in the surrounding connective tissue, is an oval gland, nearly as 

 large as the testis, from which three tube-like structures pass to- 

 wards the cloaca. Whether any one of these is a duct I 

 am unable to say, nor could I with dissection with an ordinary 

 lens detect an opening within the cloaca, but they' all passed 

 towards it, as shown in fig. 5. 



Marsupium.— In Mr. Benham's notes he described the female 

 as possessing a pouch which opens backwards, and, in my own 

 preliminary description, I have described such as existing in the 

 following terms : — "About 15 mm. in front of the vent there is a 

 pouch in the integument about four mm. wide, with the opening 

 directed backwards, and having a depth in a forward direction of 

 from four to five 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." See Plate Y., fig. 3. The 

 condition of this specimen, which was apparently the only female 

 I had then received, made all observations in reference to soft 

 parts of doubtful value. 



I am now, however, able to confirm these statements by an 

 examination of the specimens recently obtained, for, four of 

 these are undoubtedly females. Two possess a pouch, which is so 

 well developed as to suggest that it has recently been occu- 

 pied, and in two the organ is small and rudimentary. In that 

 in which the pouch is largest, a groove in the integument, 

 bounded by two well-marked pillars, begins just in front of the 

 anus, and leads uninterruptedly forward into a cul-de-sac, which 

 readily admits a glass rod 5 mm. in diameter. This p(juch 

 terminates at a point about 15 mm. in front of the anal orifice, 

 and it thus opens backwards. Sparsely scattered over the integu- 

 ment, lining the interior of the pouch, are reddish hairs ; Ijut 

 examination with a hand lens did not enable me to detect any 

 nipple or orifice. A narrow margin of somewhat bare integument
