of the Island of Trinidad, W. I. 369 



Y. 



In addition to the species given in the catalogue, several 

 others are noticed in the subsequent remarks on their habits 

 and uses. It is said that " Besides the above, there are the 

 common eel (Anguilla) and the Coscorob, very common in 

 ponds and rivers, the cats (Callichthys?). I have also been told 

 that a trout is not scarce in our mountain streams ; this fact I 

 have not been able to ascertain." 



There are two species called " Coscorobs," both of which 

 belong to the family of Chromididse and the genus Cychlasoma 

 of Swainson, or Acara of Heckel ; they might have been placed, 

 as had been done by previous writers, in the genus Chromis. 



The " common eel " we were unable to obtain, but there is 

 undoubtedly a species of eel which is not a Synbranchus, and 

 which probably belongs to Auguilla or some allied genus. We 

 have never seen it. 



The common river cat-fish or Pimelenotus was twice brought 

 to us as the trout, but as the species mentioned by Dr. Leotaud 

 is said to be found in the mountain streams, it is probably a 

 different fish, and perhaps belongs to the family of Characini of 

 Miiller and Troschel. 



We have been unable to identify the fishes called by the 

 Doctor " Cats (Callichthys ?)." They have never been seen 

 by us, and we were never able to obtain a description from 

 any of the residents. Do they belong to the genus Doras of 

 Lacepede ? 



A species of Siluroid has been described to us as resembling 

 the common river cat-fish in almost every feature, but wanting 

 the barbies ; it was stated to be very rare, and only found in 

 the Caroni river, the chief stream on the western side of the 

 island. This fish very probably belongs to the genus Ageniosus 

 of Lacepede.
