VOYAGE TO THE 
are few here, but the brown sea-guana* and a red-breasted 
lizard are to be seen in great numbers. We saw only one 
green snake, quite harmless, and found but few insects; 
however, our stay here was too short to procure any thing 
like a perfect catalogue of the natural productions of the 
Islands. 
March 30.—We left Banks's Cove, and about noon came 
to a curious steep insulated rock called Redondo, round 
which we caught a great quantity of fish, and saw innume¬ 
rable sharks. In the night we made Abingdon Island, and 
sent boats in the morning to hunt for terrapin, but owing 
to the strong west-north-west current they could not land. 
* Brown sea-guana, an amblyrhyncus, which at. first the editor supposed 
might he the female of the black one, but on comparison the two animals 
appear so different as to induce the belief that they are distinct species. The 
measurement of a brown one, brought home by one of the lieutenants, is as 
follows: Length from the nose to the tail, one foot seven inches; length of the 
tail, one foot eight inches; height at the shoulder, nine inches; girth under the 
fore feet, one foot one inch ; belly, one foot four inches; length of longest toe, 
two and a half inches, which is quite different from the black one, described by 
Bell: there is besides a great difference in the crest, which in the black consists 
of sharp flat scales, issuing like those of the alligator, and continuing quite to the 
end of the tail. In the brown one the crest is of thick round spines, of not 
near the height of those on the black one, and only extending to the back of the 
blade bones. The scales on the head and face of the brown are thick, pentan¬ 
gular, embossed; those of the black run into sharp spikes: the colour is a red 
ochrey brown, except the head, which is yellow.
