Characters of the Striked Hycena (&c. 341 



that the animal discharges the secretion when attacked *, is 

 suggestive of the use of the secretion for defence to make 

 good the deficiency of the teeth in that respect. 



Since the above-given account of the female Ht/ana hycena 

 was written, a male of the same species, also from India, 

 has come into ray hands. Apart from its sexual organs it 

 agrees with the female in all essential respects. 



Although the external sexual organs of the male were 

 described and illustrated by Daubenton, neither his descrip- 

 tion nor his figures are quite as detailed as is desirable. 

 The following account of them may therefore prove use- 

 ful :— 



The scrotvim (fig. 5, A, B, sc), as in Crocuta, is not a 

 prominent or pendulous sack, but consists of an area of 

 naked skin slightly raised above the level of the surrounding 

 integument and marked with a median groove. It looks 

 backwards just beneath the lower edge of the anal sack, and 

 is separated therefrom by a hairy tract of skin. The 

 perineal region beneath the scrotum inclines convexly for- 

 wards, and the prepuce forms an excrescence far in advance 

 of the scrotum in approximately the same position on the 

 prepubic area as in the Canidse and Ursidee and in some 

 ^Eluroids, e. g. Cryptoprocta and Par-adoxurus. Dorsally 

 the prepuce is tied closely to the abdominal wall, so that 

 the penis when retracted is in no sense pendulous (fig, 5, 

 A, B, pr.). 



When the skin of the prepuce is cut along its ventral 

 side and turned over laterally, the glans penis, ovate in 

 outline, is seen lying with it (fig. 5, F, gl.). The apex of the 

 glans (fig. 5, C, G, gl.) is obliquely truncated, the inferior 

 edge being more prominent than the superior, and has a 

 shallow median orifice formed by a prominent rim of 

 wrinkled or puckered skin, suggesting two labia or lips 

 which can be pulled back on each side of the rigid central 

 portion, and this is provided dorsally with a smooth low 

 ridge, cartilaginous in consistency and ending in a point, 

 beneath which is placed the aperture of the urethra (fig. 5, 

 D, E). As Daubenton observed, the outer wall of the glans 

 is beset with minute recurved spicules. 



Owing to the elasticity of the skin of the prepuce 

 (fig. 5, G) and of the tissue of the penis, the latter organ is 

 capable of being drawn out, so that it projects about four
