In this statement the General has not marked the time of 

 gestation, nor the period of the rutting season j and we 

 regret the omission of the number of mammae in the female, 

 as they are at least a secondary character for the distinction 

 of groups. 



The Four-horned Antelope. (A. Quadricornis.) It is a 

 question whether the skull in the Royal College of Surgeons 

 be of the Chickara or not : the length, position of the 

 upper horns, and their direction, are similar, but the spu- 

 rious horns are subtrigonal, and of a yellowish colour on 

 their internal face, possessed of three wrinkles or small 

 annuli at the anterior base, robust » vertical, and one inch 

 and two-thirds long. The head is narrower than the former ; 

 the frontals are prolonged above one inch before them, 

 having on each side a wide open space, and the nasal bones 

 begin consequently lower down. In front of the spurious 

 horns are several rugosities ; the parietal is broad, and 

 surmounted by an elevated crest of the sinciput ; the su- 

 perior arch of the orbits is also more straight than usual, 

 and more prolonged over the eyes. In this specimen the 

 osseous cores of the superior horns alone remain two 

 inches and three-quarters long, but no comparison can 

 be made of the horny sheaths themselves ; the skull is 

 something above seven inches in length *. There is a 

 second skull in the Museum of Mr. Brooks, from which, we 

 believe, Dr. Leach drew the characters of his Tetracerus 

 Striaticornis. It is, perhaps, worth remarking, that in this 

 racemus the interorbital horns appear to be composed in 

 the greater part of corneous matter, with only a short 

 bony nucleus within. 



* M. de Blainville, mistaking the meaning of the ticket attached 

 to the head, says, it is named Hoornadabad in India, whereas the 

 specimen is stated to have been brought from Moorshadabado
