1881. J DR. M. WATSON ON THE SPOTTED HY^NA. 519 



On the glans clitoridis of the virgin female which I formerly 

 described, I failed to distinguish any trace of the recurved spines 

 which beset the glans penis of the opposite sex. In the mature 

 female, on the other hand, the glans clitoridis is invested by a number 

 of minute spines, which, however, were neither so numerous nor of 

 so horny a nature as the corresponding structures of the male organ. 

 The presence of these spines in the mature female and their absence 

 in the virgin appear to show that they are structures of compara- 

 tively late growth. 



Nipples.- — The nipples in the female which has produced young 

 are four in number. Of these two are of small size and had appa- 

 rently never been functionally active. They are situated one on 

 either side of and almost in contact with the side of the prepuce. 

 They are symmetrically placed near either side of the middle line, 

 and are separated from one another by a distance of 1| inch. Of 

 these two nipples, the right is smaller than the left. The other two 

 nipples were of large size; and both had evidently given suck. Like 

 the first pair, they are situated symmetrically on either side of the 

 middle line, at a distance of 2\ inches from the latter and 3 inches 

 in front of the free border of the prepuce. Each measures 1 g inch 

 in length. In the second male which I examined I could only dis- 

 tinguish a single pair of rudimentary nipples. They were sym- 

 metrically disposed, one on either side of the free margin of the 

 prepuce, but not in contact with the latter as in the mature female, 

 but separated from the prepuce by a distance of 2 inches. It will 

 be seen, therefore, that in the two sexes the nipples neither cor- 

 respond in respect of number nor of position. 



in my^previous papers I showed that in the female the anal scent- 

 glands much exceeded in size those of the male. Further observa- 

 tions on the size of these glands in the two specimens last examined 

 show that the anal glands in both sexes are of the same size, and 

 that they equal those of the virgin which I first dissected. Probably 

 the difference in size of these glands in the two male specimens is ex- 

 plicable on the supposition that the specimen last examined had 

 attained greater sexual maturity than the first, and that the anal 

 glands, like certain of the sexual glands, only attain their full size 

 some time after sexual maturity has been reached. 



Male. 

 In a former communication' I directed attention to the difference 

 between Prof. Flower's observations and my own with regard to the 

 presence of a prostate gland in the male Hijcena crocuta. The 

 examination of the male which I received last summer proved that 

 a prostate gland is undoubtedly present in the male of this animal, 

 as described by Professor Flower. Its form in the specimen 

 referred to exactly agrees with the description which I formerly 

 gave, founded upon an examination of the organs which Prof. 

 Flower kindly placed at my disposal. The prostate (Plate XLIX. 

 fig. 4) consists of two distinct masses, each measuring 1 inch in
