Only four (2%) species, one of which has already been listed as 
occurring in Japanese waters, are also recorded from the Atlantic 
littoral regions, principally from the Bermudas, West Indies and the 
Gulf of Mexico: 
Crangon dentipes* Bermudas, West Indies, Key West, 
Mediterranean, Cape Verde Islands. 
Processa canaliculatay North Carolina to Trinidad, Bermudas, 
West Indies, Gulf of Mexico; Europe 
(also Japan and Amboina). 
Epialtus bituberculatus Bermudas; Indian River, Florida, to 
Brazil (also Chile). 
Pachygrapsus transversus} Bermudas; Bahamas and Florida Keys 
to Rio de Janeiro, Brazil; West 
Afriea (also Oriental region and 
Galapagos Islands). 
Of these the second and fourth are cosmopolitan with respect to their 
distribution. 
Two species are pelagic, Plewroncodes planipes and Planes minutus. 
The first is known only from the Pacific shores of America ranging 
‘‘90 miles S.W. of San Francisco to 150 miles S.W. of Cape St. 
Lueas’’; while the second is a more or less cosmopolitan form found 
in temperate and tropical seas throughout the world. The latter might 
properly be included in both the preceding lists. 
Five (3%) species have a bathymetric range exceeding 500 
fathoms, and even two. of these have been taken in over 1000 fathoms, 
as follows: 
Munida quadrispina® 50— 559 fathoms 
Munidopsis quadrata 47— 859 fathoms 
Munidopsis aspera; 69-1500 fathoms 
Chorilia longipes* 27— 603 fathoms 
Chionoecetes tanneri°* 29-1625 fathoms 
All of these are confined to the Pacific except Munidopsis aspera, 
which has also been taken in the Atlantie off Brazil (type locality) 
and which, except for its strictly abyssal record there, 1500 fathoms, 
might well be included among the Atlantic forms above. It can, how- 
ever, be called a cosmopolitan form for all primary abyssal forms as 
a rule are cosmopolitan, or would prove to be more or less so were the 
deep sea thoroughly explored.
