GEOGRAPHICAL DISTRIBUTION OF CRUSTACEA. 1561 



Callao, Peru. The Eurypodii of the Patagonian seas sometimes reach 

 as far north as Valparaiso. 



Among the Tetradecapoda, Amphoroidea typica is a peculiar species, 

 yet it closely resembles a species from Australia. Other genera of 

 Tetradecapoda represented in Chili, are the following : — Epelys, Por- 

 cellio, Lygia, Spheroma, Desmarestia (Nicolet), Orchestia, Allorche&tes, 

 Iphimedia, Amphithoe, Aora, Hyperia, Primno, Pro?we, Oxycephalus. 



4. The Araucanian Province (cold temperate), extending from 

 Valdivia nearly to the parallel of 50°. Length, nine hundred miles. 

 The genera Eurypodius and Lithodes occur on this coast, and probably 

 also Platyonyclxus and Pseudocorystes ; but the Araucanian species have 

 not yet been studied. 



South of the Araucanian province lies the South Patagonian and 

 Fuegian, the latter of which properly falls into the Antarctic kingdom. 



III. NORTH TEMPERATE SUBKINGDOM. 



1. The Sonora Province (warm temperate) along the California 

 Peninsula. Length, five hundred and fifty miles. 



2. The Diego Province (temperate), extending from just below the 

 entrance of the Peninsula, in latitude 28£° to latitude 34£°, and in- 

 cluding the port of San Diego. Length, four hundred and fifty miles. 

 A species of the genus Pugettia and an Albunhippa (a Peruvian genus) 

 occur on this coast. 



3. The Californian Province (subtemperate) extending beyond 

 the Bay of San Francisco to Cape Mendocino. Length, four hundred 

 and eighty miles. This region has a close resemblance to the Chilian, 

 in some of its genera, which is also subtemperate. Thus there are 

 three species of Cancer, two of Epialtus, and one of Libinia. The 

 Libinia is closely like the L. dubia of the United States, if not iden- 

 tical with it. 



4. The Oregon Province (cold temperate), extending probably to 

 Puget's Sound. Length, about four hundred and eighty miles. The 

 Orangon vulgaris, common in Northern Europe, occurs on this coast, 

 and the Echidnocerus of White (near Lithodes) is reported from the 

 mouth of the Columbia. 



5. The Pugettjan Province (subfrigid). Length, about twelve 

 hundred miles. This province has some distinctive genera, as Ore- 

 gonia (related to Eurypodius), Chorilia, Scyra, and Telmessus; also,
