CATOMETOPA. 

 Family OCYPODIDJE Leach. 



This family is represented in Bermuda only by the genus Ocypode. 

 The "fiddler-crabs" (genus Uca or Gelasinms), so abundant on 

 most coasts of warm countries, are entirely lacking, so far as known.

This crab is easily distinguished by its thick, quadrate carapace, 

 coarsely granulated on the sides, with finer granules on the middle 

 and posterior parts ; the acute anterior angles ; and the very larg$ eyes 

 and eye-stalks. The eyes are abruptly rounded distally, but pro- 

 longed proximally on the stalks beneath. The chelipeds of the males 



* Kiiigsley, op. cit., p. 184, used the specific name arenarin, as from Catesby, 

 1731 and 1771, dating it from the later edition. That edition was edited by 

 George Edwards, who gave binomial names to the species of Catesby. There 

 is no valid reason for not adopting them when they have priority, as in this case. 

 The name Cancer arenarius is given in the text and is also engraved on the plate.
