and Central America. But a character hitherto not recognized 
does separate the two genera nevertheless. That is the posses- 
sion, by Cyclura, of corneous combs on some of the posterior 
digits, specialized from the ordinary lateral scales, which have 
also comb-like free edges in both genera. The species of this 
genus known to me are thus defined: 
I. Scales of muzzle all small; combs on third toe only.

The C. carinata inhabits the Turks island, whence a specimen 
was brought to Philadelphia by Professor A J. Ebell in 1868. 
The C. nubila is Cuban. It is the C. harlani of De la Sagra’s 
history of that island. The.C. ġæolopha is/from Andros island 
of the Bahama group (see Proceedings of Academy Philada., 
1861, p. 123). The C nigerrima is a new species from Navassa, 
On the summit of the muzzle are two pairs of large scuta in 
front of the median tuberosity, separated by granular scales. 
oi Metopocerus cornutus there are said to be three pairs of 
these scales. This animal also differs from the M. cornutus 
asa porcupine, and skii bÉ fruits. —Ē. D. Cope.
