This remarkable lizard of a very distinct monotypic genus is wholly con- 
fined to Cuba. It occurs in all parts of the Island where there are forests both 
in lowlands and highlands. We have seen or collected specimens at Aguada 
de Pasajeros, vicinity of Manzanillo, Los Negros in Jiguanf, La Maya near Alto 
Songo, and about Guantanamo. There is a specimen in the M. C. Z. from 
near San Diego de los Bafios in western Cuba. The species is rare everywhere 
and is one which is universally feared by the natives, who believe it to be very 
venomous. Of the breeding habits of this lizard nothing is known. The only 
young examples which have been recorded were two taken by the junior author 
at La Maya, and “El Corojo” de San Carlos, Guantanamo, and a very young 
one taken during its first shedding, its umbilical area scarcely closed, by the 
senior author in October, 1918, on the Sierra de Andfe near Guayabal, Havana 
Province. The second mentioned young example which is about 37” from 
snout to vent has a series of barbel-like scales, soft and almost hair-like, ex- 
tending from the symphysis of the lower jaws to the origin of the dewlap. In 
all respects they are similar to the adults except that the head is markedly 
Anolis-like and lacks the casque-development with its characteristic ornamenta-
