THE NAUTILUS. 103 
A LIST OF THE BRACHIOPODA, PELECYPODA, PTEROPODA, AND NUDI- 
BRANCHIATA OF JAMAICA, LIVING AND FOSSIL. 
COMPILED BY 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 compilation was prepared during the time I was 
Curator of the Jamaica Museum, and is, I think, almost as complete 
as the present state of knowledge will permit. But for the kindness 
of Mr. H. Vendryes in permitting 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 Carpenter. 
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 remind students 
that there is a rich but unknown 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 many 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 frequently brought to me at the 
Jamaica Museum, which I might easily have supposed Jamaican, 
without careful inquiry ; such specimens 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
