THE NAUTILUS. 10-"> 



A LIST OF THE BRACHIOPODA. PELECYPODA, PTEROPODA, AND NUDI- 

 BRANCHIATA OF JAMAICA, LIVING AND FOSSIL. 



COMPILED P.Y T. D. A. COCKERELL. 



No list of the bivalve Mollusca of Jamaica- has ever been pub- 

 lished, and many of the commonest species are unrecorded from the 

 island. The present compilalion was prepared during the time I was 

 Curator of the Jamaica Museum, and is, I think, almo.«t as complete 

 as the present state of knowledge will permit. But for the kindness 

 of Mr. H. Vendryes in permittii g me the free use of his collections 

 and MSS. the list could never have been prepared, and it is, in the 

 main, a monument of his industry, extending over a great number 

 of years. Mr. Vendryes informed me that the specimens recorded 

 by him might be regarded as correctly identified, as not only has he 

 given them careful study himself, but they were submitted to and 

 verified by Messrs. Swift and Carj)enter. 



All records are given as I found them, in alphabetical order 

 under each group; synonymy being indicated by cross references. 



The solitary nudibranch at the end may serve to lemind students 

 that there is a rich but nnknoivn, nudibranch fauna in the seas 

 around Jamaica. 



[Since writing the above, I have submitted the list to Mr. E. A. 

 Smith, who has most kindly indicated some rectifications in the 

 generic nomenclature, and searched some works inaccessible to me, 

 with the result of discovering several additional records. Mr. 

 Smith thinks that a thorough search through the different mono- 

 graphic works, and the older books, would reveal nuny other 

 records. I regret I have neither time nor opportunity to make this 

 search, but I do not think many reliable records would be found. 

 Mr. Smith has discovered seven records (indicated in the list 

 within brackets) which are certainly erroneous, and in the case of 

 easily-recognized species attributed by older authors to Jamaica, but 

 not found there since, I think we may well express some doubt. 

 Specimens of various kinds were fre(piently brought to me at the 

 Jamaica Museum, which I might easily have supposed Jamaican, 

 without careful inquiry ; such sj)ecimens would be from Colon prin- 

 cipally, but in former days, when Jamaica was on the highway to 

 the Pacific and antipodes, they might have come from more distant
