GEOGRAPHICAL DISTRIBUTION OF CRUSTACEA. 1563 



eminently Torrid zone genera. The northern species, Bernhardus poV- 

 licaris, Platyonychus ocellatus, Lupa dicantha, Phnopceus limosus and 

 Herbstii, reach as far south as Key "West. 



3. The Brazilian Province (subtorrid), including the harbour of 

 Kio Janeiro, and extending north nearly to Bahia. Length, six hun- 

 dred miles. The species of Crustacea are numerous, and have close 

 relations to those of Key West. Among the species peculiar to the 

 province are the following : — Leucippa levis, P'dumnus Quoyi, Lupa 

 spinimana, Eucrate crassimanus, Chasmagnathus granulatus, Hemi- 

 grapsus granulans, Hepatus fasciatus, H. angustaius, Sicyonia carinata, 

 etc. The number of species of Caprellids and Cymothoids is large. 

 The following species are common to Kio Janeiro and Key West, or 

 the West Indies : — Acantlionyx Petiverii, Gelasimus maracoani, and Q. 

 vocans, JJca levis?, Xaniho parvidus, Lupa dicantha, Arenceus cribra- 

 ria, Ocypoda arenaria, 0. rhombea, Goniograpsus ruricola, Cardisoma 

 guanhti7ni, Scyllarus eqainoctialis, Penceus brasiliemis, Pagurus granu- 

 latus, etc. Epialtus marginatus occurs also at the Gallapagos, and 

 Menippe Rumphii y reported as Brazilian, belongs to the East Indies. 



II. NORTH TEMPERATE SUBKINGDOM. 



1. The Carolinian Province (warm temperate), extending along 

 by Northern Florida, Georgia, and the Carolinas to Cape Hatteras. 

 Length, six hundred miles. Several Key West species occur also in 

 this province ; for example, Libinia dubia, Mithrax hispidus, Menippe 

 mercenarius, Arenoeus cribmria, Ocypoda arenaria, Sesarma reticulata, 

 and S. cinerea, Plagusia squamosa. Still, the general character of the 

 species is different. Among the peculiar species mentioned by L. R. 

 Gibbes, are Leptopodia calcarata, Pisa mutica, Cryptopodia granulata, 

 Pilumnus acxdeatus, Hepatus decorus, Guaia punctata, Porcellana macro- 

 cheles, Albuncea scutellata, Callianassa major, Gebia affinis, Alpheus 

 neterochelis, A. formosus, and Pontonia domestica. The following northern 

 species have Charleston as their southern limit : — Libinia canaliculata, 

 Cancer Sayi, Bernhardus longicarpus; Squilla empusa also reaches from 

 Florida to New York. The warm-water genera of Cancroids are all 

 absent ; the species of Hepatus indicates a relation to the Chilian and 

 Brazilian provinces. 



2. The Virginian Province (cold temperate). It extends from Cape 

 Hatteras to Cape Cod, including the shores of Virginia, New Jersey,
