INTRODUCTION 



Hughes in his "Natural History of Barbados", 1750, ^ enu- 

 merates fifteen kinds of crabs, but the descriptions are so brief 

 and the names so trivial that it is impossible to determine most 

 of the species with any great degree of certainty. Only two of 

 the brachjairan crabs are figured; one, the Homed Crab (pi. 

 XXV, fig. 3) is an undoubted Stenocionops furcata, the other, 

 the Lazy Crab, (pi. XXV, fig. 1) is a composite, having the 

 chelipeds and ambulatory legs of Mithrax spinosissimus attached 

 to the body of a Parthenopid crab, Daldorfia horrida {= Parthe- 

 nope horrida of authors), an Indo-Pacific species. 



From the dredgings of the U. S. Coast Survey steamers 

 "Blake" and "Hassler", A. Milne Edwards i in 1880 published 

 a list which includes thirty-eight species of brachyuran crabs 

 from the waters about Barbados. This is supplemented by the 

 later report (1902) on the Oxystomes of the same collection by 

 Milne Edwards and Bouvier,i which adds three species to the 

 earlier list. 



The present expedition obtained ninety-three species of 

 braehyurans of which only one species is found to be undescribed. 

 The range of twenty-nine species is extended by their capture at 

 Barbados.
