314 HABITS OF CRUSTACEANS. 



in those localities. To these may be added new species 

 of Hippa, Remipes, Trapezia, Macrophthalmns, Pilumnus 

 and others, which will be described in another place. 



In many parts, these islands are over-run with various 

 kinds of Sesarma, the species of which differ very much 

 in their habits. Among those I detected as belonging to 

 the Fauna of the Meia-co-shimah Group, one was found 

 under stones, on sandy flats just below high- water mark; 

 another inhabited the coral reefs ; a third, fresh- water 

 rivulets and pools, hiding under stones and logs, and 

 climbing the roots of trees with great facility. Another, 

 allied to 8. affinis, De Haan, has the same habits ; another 

 species, with the same love of climbing and hiding under 

 stones, runs more upon the dry land, among the roots of 

 grass, &c., and is very agile. One, of a marbled, light 

 sandy colour, with pale grey blotches, lives in the holes 

 of the sand, in brackish pools ; another, with a hairy 

 carapace, dark brown and purple, inhabits holes in the 

 sandy beach above high-water mark ; while in another 

 part of the world, I found a species living in fresh-water 

 rivulets among weeds; and in the forest of Celebes 

 another under damp stones and logs, at some consider- 

 able distance from fresh-water ponds. 



Most of the Dorippe inhabit deep water, from twenty 

 to thirty fathoms, living on a muddy bottom. They are 

 very numerous in the China Sea. The Chinese fishermen 

 often bring them up in their nets, and among large 

 numbers which I have observed in their boats, I have 

 found nearly every individual with an adventitious body 

 (I believe an alcyonoid sponge) attached to the carapace, 

 and retained in its position by the hooks of the two small
