of scrotum. The extremities of the epldidymis or globi were propor- 

 tionately large. The vas deferens had a blind process on each side. 

 The urinary bladder was contracted, and its coats consequently were 

 thick : the membranous portion of the urethra was one inch and a 

 half long, and its canal wide. The prostatic glands, analogous in 

 their situation to Covvper's, were two in number, and as large as the 

 testes ; each terminated by a single wide duct, a few lines from the 

 extremity of the glans. An interesting provision exists to prevent the 

 secretions of these glands being driven into the large extent of urethra, 

 which lies between them and the bladder : the inner membrane of 

 the canal is raised in a semilunarfold behind the entrance of the ducts, 

 which must act as a very complete valve during the turgescent state 

 of the parietes of the canal. The penis is about eight lines in length ; 

 the glans of a pointed form, unarmed, the external orifice a lon- 

 gitudinal groove directed backwards. 



" Both animals died with the pupil expanded, and of a circular 

 form." 



A description of the Chiru Antelope, by B. H. Hodgson, Esq., 

 dated Valley of Nepal, Oct. 18, 1830, was read. This animal, the 

 supposed Unicorn of the Bhotians, was first described imperfectly 

 by Dr. Abel, from an injured skin, and the notes of Mr. Hodgson. 

 Dr. Abel gave to it the name of Antilope Hodgsonii ; and it has 

 subsequently been mentioned by M. Lesson as the Ant. Chiru, and 

 by Major Hamilton Smith as the Ant. Kemas? Opportunities which 

 have occurred since his original notes were prepared have enabled 

 Mr. Hodgson to make some additional observations on other indi- 

 viduals, the results of which are given in the present paper. The 

 species may be characterized as follows : 



ANT. HODGSONII, Abel. Ant. cornubus longissimis, compressis, 

 gradatim attenuatis, suberectis, lyratis, annulis 1 5-20 antice pro- 

 minentibus, apicibus tantum lcevibus : vellere duplici ; interno la- 

 nato cinerascenti-cceruleo ; externo piloso superne cervino, iiiferne 

 albo : tumore molli utrinque supra nares. 



Fcem. simillima? 



Longitudo circa 5 ped. ; alt. ad humeros 2| 3 ped. 



In form the Chiru Antelope approaches the Deer. Its limbs arc 

 long and slender, but not weak : its neck is also rather elongated 

 and slender : its head tapers forwards, but is somewhat deficient in 

 elegance on account of the nasal tufts, and of a rather unusual 

 quantity of hair and bristles about the mouth and nose. In its or- 

 dinary attitude the line of the back is nearly horizontal; the neck 

 is bowed outwards and downwards, so that the head is carried not 

 much above the level of the back j and there is a stoop in the hind 

 legs on account of which, though they are rather longer than the 

 fore legs, the hind quarters are not perceptibly raised. 



The ears and tail are moderate, and devoid of any peculiarity; 

 so likewise are the suborbital sinuses. The horns are exceedingly 

 long, measuring in some individuals nearly two feet and a half. 

 They are placed very forward on the head, and may be popularly 



said
