V. PORTUNIDtE. 



The large species of this family are much esteemed as food among the poor islanders 

 of the Meia-co-shimahs, and in the markets of China large species of Neptmus {N. pelagicus), 

 are frequently offered for sale. Two well-marked genera have been added to this group by 

 our researches in the Eastern Seas, besides numerous species. The island of Balambaugan, 

 at the north end of Borneo, harbours the Lupocyclus, which is very active in its habits, 

 keeping close in shore like Lupa, Oceanus, and other swimming crabs ; it swims by rapid 

 jerks along the bottom, and, when caught, will wound the fingers by striking side-ways with 

 its spiny fore-legs. The other new genus, Lissocarcinus, was obtained at some considerable 

 distance from land, concealed in the internode of a fragment of floating bamboo, and is a 

 powerful swimmer. The Cancer (T/talamita) admete of Herbst, and the Cancer {TJialamita) 

 prymna of the same Crustaceologist, besides three new species of Amphitrite, and a new 

 species of Neptimus, were likewise procured.
