320 PROCEEDINGS OF THE ACADEMY OF [1888. 



Nautilograpsus minutus, L. 



One small specimen dredged off Shelly Bay. 

 Grapsus maculatus, Catesby. 



One large female, and numerous empty shells from Harris's Bay, 

 south shore. 



Pachy grapsus transversus, Gibbes. 



Numerous specimens, including ovigerous females ; very abundant 

 on the rocks about the mouth of Harrington Sound, and also on the 

 Pigeon Rocks, Bailey's Bay. 



Recorded from Florida, West Indies, Australia. 



Cyclograpsus integer, Milne-Edwards. 



One small female. Species recorded from Brazil and Florida. 

 Goniopsis cruentatus, Latr. 



One female, from the mangrove swamp of Hungary Bay, south 

 shore. Although the species was very abundant at this locality we 

 only succeeded in catching a single individual. The mangrove crab, 

 or " mangrove climber " as the animal is sometimes called, burrows 

 among the thickets of mangrove stems and roots, up which it not 

 infrequently climbs to a height of several feet. The great similarity 

 existing between its coloring aud that of the bright and partially 

 withered leaves of the mangrove, especially in the shades of yellow 

 and red, renders the animal difficult of detection, and often at a 

 distance of only a few feet, buried among the fallen leaves, these 

 agile creatures escaped observation, even when attentively sought 

 after. We have here one of the most remarkable instances of 

 protective coloring, or semi-mimicry, with which I am acquainted. 



Sesarme cinerea, Bosc. 



Numerous specimens, from the beach of Flatts Village. The 

 species was seen almost everywhere scampering over the rocks. 



Calappa fiammea, Herbst. 



A single male individual obtained through purchase. Species pre- 

 viously recorded from the Bermudas. 



ANOMURA. 



Petrolisthes armata, Gibbes. 



Five specimens., obtained on the beach of Flatts Village, appear to 

 be identical with the form described under this name from Florida,
