The Four-horned Antelopes of India. v 89 



I now proceed to a summary but very carefully compiled descrip- 

 tion, or definition rather, of the five species thus far discovered. 



1. T. chickara, Hardwicke. Uniform bright bay ; chin, abdomi- 

 nal, centre of neck, belly, insides of limbs near it, edge of buttocks 

 and of tail, and lining of ears, albescent. Horns and hoofs and 

 muzzle, black. Snout to vent 2ft. 9in. Height \ft. S\in. Head 

 7\in. Ears 4fm. Tail bin. Posteal horns 3in., rounded, smooth, 

 unringed, straight, erect, curved slightly forward, subdivergent ; 

 their basal interval Jt». ; their terminal, \\in. Anteal horns fm. 

 long, stumpy, erect, cylindric, smooth, wholly unringed, blunt ; their 

 basal interval %in. Female, size of a male, but paler coloured. 



Habitat — Bengal, Behar, Orissa. 



2. T. quadricornis, Blainville. Size of the precedent. Colours 

 above brownish, beneath greyish. Head l\in. Posteal horns longi- 

 tudinally striate, transversely striolate, with rings at the bases. 

 Anteal horns \\in. long, subtrigonal, robust, acute, basally ringed, 

 yellowish inside, black for the most part, like the upper pair and 

 the hoofs. Anteal horns set on anteriorly to mid line of orbits, 

 whereas in Chickara they are posterior to that line. 



Habitat — India, the part of, unknown : described from sculls and 

 horns and Du Vaucel's drawings. Distinguishable at once from the 

 last by its acute and perfect fore horns, in place of the blunt stumps 

 of Chickara, a permanent distinction, though Mr. Gray inclines 

 against the notion, and therefore confounds the two species. He 

 should have adverted to the next species, long since on record, and 

 which settles that question. 



3. T. subquadricornutus, Elliott. Dull brown, approaching 

 to fawn, darker than in Cervicapra, less bright and less deep than in 

 the Gazelle. Mid belly, and chest, insides of limbs near them, and 

 lining of ears, albescent gradually. Bridge of nose, fronts of entire 

 limbs and fetlocks posteally, dark : 3ft. Gin. long and 2ft. \\in. high. 

 Head Sin. Ears \\in. Tail 5in. Posteal horns 4J to 4fm., black, 

 reclining, straight but with a very slight bowing to the front, 

 parallel, three or four small wrinkles at their bases. Anteal horns, a 

 mere rudiment. 



Habitat — Southern India.
