CONCERNING A SPECIES OF LIZARD FROM 
CLIPPERTON ISLAND. 
BY SAMUEL GARMAN. 
On account of its probable derivation more than ordinary 
interest is attached to the lizard described below. ‘The little 
island from which the species was taken is said to be “a rock 
about three miles in diameter,” situated in Latitude 10° 14’ North, 
and Longitude 10g° 19’ West, off the western coast of Mexico 
seven hundred miles, more or less, from the nearest part and five 
hundred miles or more south and east from the islands of the 
Revilla Gigedos group. The locality has been visited but rarely, 
by accident or in searches for guano, since its position was 
determined, in 1839. Although most completely isolated by 
distance, comparative proximity to Mexico leads one to expect 
whatever animals have obtained a foothold on it to be in some 
way more closely allied to North American species than to others ; 
the supposition being that the faunal relationships should some- 
how resemble those obtaining between the Galapagos Islands and 
the mainland of South America. In the case of this lizard the ex- 
pectations are entirely at fault; its affinities with North American 
species of its genus are of the remotest character, but on the 
other hand those existing between it and Lygosoma cyanurum 
Lesson, a species widely distributed in Polynesia, Papuasia and
