species of Pugettia, Hyas, Pseudograpsus, Pinnothera, Fabia, Trichocera, 

 with others of Bernhardus, Gebia, Callianassa, Nephrops, Crangon, 

 Paracrangon, Pandalus; and among the Tetradecapoda, there are the 

 genera Oniscus, Spheroma, Argeia, Orchestia, Allorchestes, Iphimedia, 

 and Gammarus. 



The northern part of the North American coast, including the 

 Alaschka Archipelago, belongs to the Arctic kingdom. 



B. EASTERN SECTION. 



I. TORKID SUBKINGDOM. 



1. The CARIBBEAN Province (torrid), including the West India 

 Islands, and the northern and northeastern coast of South America, 

 from the north of Yucatan to beyond Bahia. Length, along the South 

 American coast alone, about four thousand miles. There are as yet 

 no known Caribbean genera of Podophthalmia, that do not occur in 

 other Provinces in this or the other kingdoms. Mithrax and Uca are the 

 more characteristic genera, and the latter is reported elsewhere only 

 from Guayaquil, Brazil. The following are prominent forms : Chori- 

 nus heros, Pericera cornuta, and P. S-spinosa, Amphitrite forceps and A. 

 S-spinosa, Ocypoda rJumibea, Calappa marmor,ata, Atya occidentalis, Pali- 

 nurus longimanus, Palcemon Jamaicensis. The Torrid zone genus 

 Carpiliw contains two West Indian species, one of which (C. macu- 

 latus) is a cosmopolite, and allies the West Indies to the Oriental seas. 

 Dromia, although a warm-water genus, has but a single representative, 

 D. latior; and of Chlorodius, so common in the Orient, in like manner, 

 only one species has been observed, and that occurs also in the Pacific. 

 There is but a single species of Leucosidae known ; but the Caribbean 

 species of Crustacea, it must be acknowledged, are not very thoroughly 

 known. Through Leptopodia sagitiaria the province is related to 

 the Canaries. 



2. The FLORIDAN Province (subtorrid), Key West and a part of 

 Florida are here embraced, together with the Bermudas. Length on 

 the United States coast, two hundred miles. The species are mostly 

 those of the Caribbean Sea. A Libinia, Hyas, Epialtus, and Menippe, 

 have been reported from Key West and Florida, that are not men- 

 tioned as occurring about the West India Islands; also, several 

 Sesarmas, a Ranilia, and a Callianassa; these genera are none of them
