Naturalists owe a debt of gratitude to Mr. Sclater for the care and 

 clearness with which he has unravelled the meshes of confusion in 

 which the synonymy of the two very distinct species, Cariacus chi- 

 lensis (Gay) and C. antisiensis (D'Orb.), was formerly enveloped. 

 There is not the smallest foundation for a third species of Furcifer. 

 The type of Xenelaphus leucotis, &c. of Dr. Gray is preserved in 

 the British Museum, and is undoubtedly nothing but a very fine old 

 male C. antisiensis with strongly developed abnormal antlers.

1850. Coassus, Gray, P. Z. S. 1850, p. 240. 



Antlers simple spikes not exceeding half the length of the head 

 (fig. 18). Skull resembling that of Cariacus, the auditory bullae 

 less inflated and the facial profile more arched. Molars sometimes

Cariacus (Coassus) riifus. 



with supplementary columns. Canines of uncertain occurrence. 

 Rhinarium ample, resembling that of Cervulus. No metatarsal tuft. 

 Tarsal tuft present. Stature small. Form heavy, with the back 

 much arched. Young spotted. 

 Distribution. Neotropical region. 



1 If this name, which has been totally unused, were to be revived, it would 

 take precedence of Cariacus as the title of the whole genus. But it is too close 

 to Subula (Mollusca) of Schumacher, 1817.
