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.
