 The genuine Brachyura as distinguished from the Brachyura 

 Anomala include four divisions — the Oxyrrhyncha, Cyclometopa, 

 Catometopa, and Oxystomata — the family Raninidae being in- 

 cluded in the last of the four.

 This family is sometimes sub-divided into the Inachidae, the 

 Maiidae, and the Periceridae. Of the two genera here noticed, 

 Alcock places Platymaia in a sub-family Inachinae, and Scyra- 

 viathia in a .sub-family Pi.sinae. Since J^isa, J^each, is a 

 synonym of the same author's Blashts, Pit>inae, if upheld, 

 would become Blastinae, or, as a famih', Blastidae.
