524 Major-Gen. HARDWICKE on two Species of Antelope, &c. 
Major-general Hardwicke had originally described this species 
under the name of 4. quadricornis; but M. Desmarest (Ency- 
clop. ** Mammalogie," 466.) having described a species under that 
name, from a skull in the Museum of the Royal College of 
Surgeons, which appears to differ from General Hardwicke's 
species in having the anterior or short horns triangular, it has 
been judged advisable to distinguish the species now described 
by the name of A. Chickara. 
Dr. Leach has formed a new genus of the Foam hornad Ante- 
lopes under the name of Tatraceñ us.
