3. COSMOPOLITES. 
The above lists include the following species occurring in the 
Occidental, Africo-European, and Oriental seas. 
Grapsus pictus. Bernhardus streblonyx. 
Acanthopus planissimus. rangon boreas. 
Plagusia sqamosa. Crangon vulgaris. 
Plagusia tomentosa. Gonodactylus chiragrus. 
These are cosmopolite species.* The G'rapsus, Acanthopus, 
Plagusia, squamosa and Gonodactylus preéminently deserve this 
name, being found both north and south of the equator. e 
thrive in the hottest equatorial waters, and have their extreme 
limit in the temperate region. The temperature they admit of 
is hence at least from 56° to 88° F. 
The other species are cold-water species. Plagusia tomentosa 
belongs to the southern subtemperate region, being reported from 
ape Town, New Zealand, and Chili, and the rest are found in 
high northern latitudes, and probably pass from the Atlantic to 
. the Pacific Oeean through the Arctic Seas. 
Besides the above species, a few are found in the West Indies, 
which occur also in the Oriental Seas, but are not yet known 
from the European or West African coasts. These, which also 
may be styled cosmopolites, are as follows: 
Mithrax asper: East Indies; probably the same on the Peruvian 
Coas ; 
Atergatis lobatus ; Red Sea and Indian Ocean ; West Indies. i 
arpilius maculatus: East Indies ; South France ; Japan ;_ Various 
Pacific Islands from the Paumotus to the Feejees and Hawaiian Isl- 
ade West Indies ; Eriphia gonagra ; East Indies ; Port Natal ; Key

Menippe Rumphii: East Indies ; Rio Janeiro and the West Indies. 
Chlorodius exaratus : Pacific Islands ; East Indies ;, West Indies. 
Lysiosquilla scabricaudis: Indian Ocean; West Indies ; Brazil ; 
South Carolina. 5

reported from Table Bay! the East rahe, Japan and Valparaiso, — Bat we believe 
nae paraiso species to be different from that of the Indies, and have so
