Stations 80; 59; 60; 3799; 5246. Taken at 20 Siboga, 4 Monaco,

CORYCAEUS GIESBRECHTI F. Dahl 
Corycaeus giesbrechti F. DAHL, Verh. deutsch. zool. Ges. Miinchen, vol. 4, p. 72, 
1894b. 
Station 24. Established by F. Dahl upon specimens from the tem- 
perate Atlantic and afterward reported in the Carnegie plankton, by 
M. Dahl (1912, p. 88) from the Pacific, and by Sewell (1924, p. 803) 
from the Indian Ocean. It is thus widely distributed but nowhere 
abundant.

Corycaeus latus DANA, Proc. Amer. Acad. Arts and Sci., vol. 2, p. 38, 1849; United 
States Exploring Expedition 1838-1842 (Wilkes), vol. 14, pt. 2, Crustacea, 
p. 1221, 1853; pl. 86, figs. 3 a—e, 1855. 
Stations 3822; 3829; 8878; 4009; 4010; 4037; 4588 ; 5120; 5129; 5175; 
5176; 5180; 5186; 5190; 5208; 5209; 5293; 5295; 5229; 5934; 5386; 
5388 ; 5399; 5434; 5487; 5530; 5601; 5651; Sabtan Island, Philippine 
Islands. Established by Dana upon specimens from the tropical At- 
lantic and reported by Rose in the Monaco plankton, the species does 
not appear in the other lists. The present is the first record from the 
Pacific and indicates that the species is more abundant in that ocean. 
Dana said (1853, p. 1222) that the pigment of the large eyes extended 
backward on the underside of the cephalothorax, but this could not be 
verified in any of these preserved specimens.
