of critical notes by the late Dr. Liitken.'^ Recently a very interesting 

 and valuable account appeared by Dr. C. Tate-Regan, based chiefly 

 on the collection, notes, and sketches of Mr. Lechmere Guppj^, Jr.* 



In the present paper a list of all the fishes now known from the 

 island is given. Where species are represented in the collections of 

 the Academy, they are mentioned with the number of specimens 

 and their dimensions. The references pertain to the few species 

 previously known from Trinidad. While likely most of the fresh- 

 water species have been discovered, further collecting of the marine 

 forms will undoubtedly j'ield many others. Possibly seven or more 

 times as many as here listed, if not most of those comprising the 

 vast West Indian fauna, will eventuallj^ be found.
