A sINGLE specimen of this truly anomalous Goat-sucker forms part of the collection of the British Museum ;
it is the only one I have ever seen, and is, I believe, entirely new to science.

The only information I have been able to obtain respecting it is, that Mr. J. E. Gray purchased the speci-
men above mentioned from a collection of skins at Liverpool, which were said to be from Demerara.

The figure is of the natural size.
