 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- 

 inathia in a sub-family Pisinae. Since Pisix, Leach, is a 

 synonym of the same author's Blastus, Pisinae, if upheld, 

 would become Blast! nae, or, as a family, Blastidae.
