COPEPODS GATHERED BY ALBATROSS—WILSON 197 
Corycaeus ; therefore Kr¢yer’s name becomes a synonym. Fortunately 
it fits into Dana’s genus so well that its specific name does not seem at 
all out of place. 
CORYCAEUS VITREUS Dana 
Corycaeus vitreus Dana, Proc. Amer. Acad. Arts and Sci., vol. 2, p. 37, 1849; 
United States Exploring Expedition, 1838-1842 (Wilkes), vol. 14, pt. 2, 
Crustacea, p. 1216, 1853; pl. 85, fig. 9 a-d, 1855. 
Station 4009. Established by Dana upon a single male captured 
east of the Taumotu Islands in the tropical Pacific. It does not ap- 
pear in any of the plankton lists but was described and figured in detail 
by M. Dahl (1912, p. 25). The female still remains unknown. 
Genus CRYPTOPONTIUS Giesbrecht, 1889 
CRYPTOPONTIUS BREVIFURCATUS Giesbrecht 
Cryptopontius brevifurcatus GIESBRECHT, Fauna und Flora des Golfes von Neapel, 
monogr. 25, p. 109, pl. 1, fig. 7; pl. 8, figs. 1-12, 1899. 
Station 2396. Identified from this single station in the Gulf of 
Mexico; fully described by Sars (1915, p. 120). Itis not found in any 
ef the plankton lists, since it is a semiparasitic form and can be 
captured only when it leaves its host and swims about freely in the 
tow, a circumstance that apparently happens very rarely. 
Genus CYMBASOMA I. C. Thompson, 1888 
CYMBASOMA LONGISPINOSUM (Bourne) 
Monstrilla longispinosa Bourne, Quart. Journ. Micr. Sci., ser. 2, vol. 80, p. 575, 
pl. 37, figs. 14, 10, 1890. 
Caldera Bay anchorage, west coast of Mindanao, Philippine Is- 
lands. The net was set in the tidal current at the gangway of the 
steamer for 20 minutes, and in the large resultant catch were included 
five species of Monstrilloida. The present species was established 
by Bourne upon specimens obtained in the English Channel. Both 
sexes were afterward fully described and figured by Sars (1921, p. 24). 
CYMBASOMA RIGIDUM I. C. Thompson 
Cymbasoma rigidum THompPson, Journ. Linn. Soc. London, Zool., vol. 20 (1890), 
p. 154, pl. 18, 1888. 
Stations 5133, 5320; Caldera Bay anchorage, west coast of Minda- 
nao, Philippine Islands. This was the species designated by Thomp- 
son to serve as the type of his new genus Cymbasoma. The generic 
name was afterward withdrawn in favor of Dana’s genus Monstrilla, 
but when it became necessary to divide Monstrilla into two closely 
allied genera Thompson’s name was restored. As in the case of the 
preceding species both sexes were fully described and figured by Sars 
(1921, p. 21).
