St. Martin's Island, West Indies. 



Dr. R. E. Van Rijgersma collected in the lower or Dutch portion 

 of the island, likely largely at or about Phillipsburg. The collection 

 was received at the Academy in 1869. This is the most important 

 of Cope's collections embraced in his "Ichthyology of the Lesser 

 Antilles," as it furnished the largest number of his new forms. Cope's 

 account still appears to be the only one dealing with the fish-fauna 

 of this island. Species mentioned by Cope, but which I fail to 

 locate in the collection, are indicated by f. It long appeared clear 

 that a great many specimens were never included in Cope's list, 

 as I recorded some species since, and such as now remain are indi- 

 cated by the prefixed asterisk. These indications are also applicable 

 to the St. Croix and St. Christopher collections.
