pouch is occasionally absent I am unprepared to refute; but certainly my instance 
of its presence in the Spotted Hyena, and Daubenton’s and Hunter’s records of it in 
the Striped Hyena, weaken and destroy the main character on which Kaup’s generic 
division (Crocuta) is based. 
View of perineum &e. of the young male Spotted Hyena (H. maculata): pe, penis ; 
te, right testicle; a, anus; a.p, anal pouch. 
2. Of the Viscera generally. 
Each kidney, measuring 34 by 24 inches in diameter, is ovoid rather than reniform, 
the hilum being narrow but deep. Fibrous envelope structurally dense and closely 
adherent to glands. Five or six radial furrows, some terminally forked, are super- 
ficially visible; these mark veins which lie sunk in the renal tissue. On section the 
cones, eight in number, are seen to be distinct to the inner edge of the narrow cortical 
substance. 
As in carnivora, the liver is multiple, in all six-lobed. The right lobe is of con- 
siderable size; the lobus caudatus of moderate dimensions; the Spigelian lobe small. 
The bifid cystic lobe is deeply cleft, its right moiety the largest and most rounded, and 
the pear-shaped gall-bladder is lodged on it and partially in the deep fissure marking 
off the left moiety. What corresponds to a left hepatic lobe is as large as all the other 
lobular divisions taken together ; its upper border is so indented as to represent a small 
marginal lobule. 
The flat and tongue-shaped spleen is 15 inches long, and 33 inches across at the

Of the alimentary canal, the cesophagus measures about 13 inches. As contracted it
