[SCIENTIFIC RESULTS OF THE PHILIPPINE CRUISE OF THE FISHERIES STEAMER 



"ALBATROSS," 1907-1910.— No. 32.] 



A NEW GENUS AND SOME NEW SPECIES OF CRABS OF THE 

 FAMILY GONEPLACIDiE. 



By Mary J. Rathbun, 



Assistant Curator of Marine Invertebrates, United States National Museum. 



This is the second of a series of papers describing new crabs obtained 

 in Philippine and adjacent waters during the years 1907-1910 by 

 the steamer Albatross of the United States Bureau of Fisheries. 

 The first paper was published as No. 2044 of these Proceedings. 1 



The new forms here described are as follows : 

 Carcinoplax bispinosa. Ceratoplax fulgida. 



Carcinoplax spinosissima. Ceratoplax truncatifrons. 



Carcinoplax confragosa. TypMocarcinus craterifer. 



Carcinoplax purpurea. HepJithopelta apta. 



Carcinoplax angusta. Ghasmocarcinus cavimanus. 



Carcinoplax verdensis. Typlilocarcinops decrescens. 



Carcinoplax specularis. Typlilocarcinops marginata. 



Psoplieticus JiugJii. Typlilocarcinops angustifrons. 



Goneplax renoculis. Typlilocarcinops ocularia. 



Homoioplax, new genus. 



The species enumerated form an important addition to the Gone- 

 placidse. The Philippine region appears to be a favorable locality 

 for the genus Carcinoplax, as seven well-defined species are added 

 to the four already known. The occurrence of the genus Cliasmo- 

 carcinus is worthy of note, it having previously been taken only in 

 American waters. 



The new genus Homoioplax is founded on an old species. 



Family GONEPLACIDiE. 



Siabfamily CARCINOPLACIN^E. 

 CARCINOPLAX BISPINOSA, new species.
