Subgenus Dicranoceros. 



(Horns in the male only, bifurcated ; no lacrymal pits ; no inguinal follicles ; interdigital follicles 

 distinct ; four teats.) 



3713. The skull and horns of a Prong-horned Antelope (Antilope furcifer). 



From the Rocky Mountains of North America. 



Presented by Joseph Sabine, Esq. 



3714. The horns of a Prong-horned Antelope (Antilope palmata, SMITH). 



These horns have a small additional process near the angle of bifurcation of the beam : 

 they are figured by Colonel Hamilton Smith, in the ' Linnean Transactions,' vol. xiii. pi. 3. 

 From the Rocky Mountains near the River Jaune. 



Hunterian. 



Subgenus Tetraceros. 



(Horns in two pairs, short and straight.) 



3715. The skeleton of the Chickara or Four-horned Antelope (Antilope Chikara). 



The vertebral formula is: 7 cervical, 13 dorsal, 6 lumbar, 4 sacral, 12 caudal. The 

 pleurapophysial parts of the transverse process of the third to the sixth cervical vertebrae 

 inclusive forms a broad, hatchet-shaped plate, the antero-posterior extent being greatest in 

 that of the third. The Antelopine characters are well shown in the long and slender meta- 

 carpal and metatarsal segments of the limbs. The animal from which the skeleton was 

 obtained was brought alive to this country from Bengal. For an account of its admeasure- 

 ments and external characters, see the " Remarks on the Antilope Chikara," in two letters 

 addressed to the Secretary of the Linnean Society by Robert Hills, Esq., F.L.S., vol. xv. of 

 the 'Linnean Transactions,' p. 501. 



Presented by Sir Anthony Carlisle, F.R.S. 



3716. The skull and horns of a younger Chickara (Antilope Chikara). 



The deciduous teeth are retained, and the anterior horns are not developed. 



Presented by Col. Everest. 



3717. The skull and horn-cores of the male Chickara (Antilope Chikara). 



Presented by Col. Everest. 



3718. The skull of a Chickara (Antilope Chikara). 



The posterior horn-sheaths are wanting : the anterior ones differ from those of the skeleton 

 No. 3715, in being much more acuminate, and obliquely compressed on their inner side; 

 which, in a transverse section, would give them something of a lozenge form. 



From Moorshedabad. 



From this specimen, M. Blainville formed his species called Antilope quadricornis. 



Purchased.
