GEOGRAPHICAL DISTRIBUTION OF CRUSTACEA. J563 



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

 licaris, Platyonychus ocdlatus, Lupa dicantha, Panopasus limosus and 

 Herbstii, reach as far south as Key West. 



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

 Rio 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, Pilumnw Quoyi, Lupa 

 spinimana, Eucrate crassimanus, C hasmagnathus granulatus, Hemi- 

 grapsus granulatus, Hepatus fasciatus, H. angustatus, Sicyonia carinata, 

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

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

 the West Indies : Acanthonyx Petiverii, Gelasimm maracoani, and O. 

 vocans, Uca levis?, Xantho parvulus, Lupa dicantha, Arenceus cribra- 

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

 guanhumi, Scyllarus equinoctialis, Penceus brasiliensis, Pagurus granu- 

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

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



II. NORTH TEMPERATE SUBKINQDOM. 



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 

 mo'cenarius, Arenceus cribraria, 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 aculeatus, Hepatus decorus, Guaia punctata, Porcellana macro- 

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

 heterochelis, 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,
