 Invertebrates, U. S. National Museum. 



The first series of deep-sea dredgings off the coast of 

 Florida by the United States Coast Survey, from 1867 to 

 1869, m which Count L. F. de Pourtales took charge of the 

 dredging operations, yielded a large number of Brachyura 

 which were described by Dr. William Stimpson in 187 1. 1 The 

 types were destroyed in the Chicago fire. A number of the 

 species have not yet been rediscovered. 



A preliminary report upon the Crustacea collected in the 

 Gulf of Mexico and Caribbean Sea by the Coast Survey 

 Steamer " Blake" (1877-1879), was made by Prof. A. Milne 

 Edwards in 1880 3 Full descriptions of all the West Indian 

 maioid and cancroid crabs, with many illustrations, are given 

 in " Etudes sur les Crustaces Podophthalmaires de la Region 

 Mexicaine " which was published in Paris and issued in parts 

 betweeen 1873 and 1880. 



Subsequently a number of species have been described by 

 myself in the Proceedings of the United States National 

 Museum since 1891, and the Proceedings of the Biological 

 Society of Washington, 1897. Other recent papers dealing 

 with the Brachyura dredged in this region are those by Mr. 

 J. E. Ives in the Proceedings of the Academy of Natural
