V. PORTUNIMl. 
The large species of this family are much esteemed as food among the poor islanders 
of the Mei'a-co-shimahs, and in the markets of China large species of Neptunus {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 Balambangan, 
at the north end of Borneo, harbours the Lupocyclus, which is very active in its habits, 
keeping close in shore like Txupa, 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, Lissocarcims, 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 ( Thalamita ) admete of Herbst, and the Cancer ( Thalamita ) 
prymna of the same Crustaceologist, besides three new species of Amphitrite, and a new 
species of Neptunus , were likewise procured.
