NO. 3652 ISOPODA AND TANAIDACEA—MILLER 15 
Pfeffer. It possesses many of the attributes ascribed to the related 
genus Dynamenella, but the characteristic tubular posterior exten- 
sion of the pleotelson with a slit along the underside places it in 
Cymodocella. 
The generic placement is questionable, however, for several reasons. 
In Hansen’s (1905) key to the Sphaerominae eubranchiatae, Cymodo- 
cella (as well as Dynamenelia) falls into the section characterized by 
the exopod of the third pleopod being unjointed; but in the present 
specimen that structure is biarticulate. The apical tube is not as 
long as in other species of the genus. The rami of the uropod 
lamellar, as prescribed, and apically toothed, but subequal in length, 
whereas in typical Cymodocella the exopod is supposed to be con- 
siderably shorter than the endopod. Finally, because of the immatu- 
rity of the only specimen, the sexual characteristics of generic value 
could not be ascertained. 
Five species of Cymodocella are known—the antarctic-antiboreal 
CO. tubicauda Pfeffer and four African species from the Cape of Good 
Hope region; namely, C. algoensis (Stebbing) Stebbing, C. cancellata 
Barnard, C. pustulata Barnard, and C. sublevis Barnard. The facts 
that the present specimen does not fit the description of any of these 
and that it is the first record of the genus in the northern and western 
hemispheres indicate it may represent a new species. Pending exami- 
nation of additional material—hopefully, mature specimens—of both 
sexes, it seems best to defer full and formal description.

Locauiry.—Hawaiian Islands: Port Allen, Kauai (Station 100). 
Remarxs.—The family Cirolanidae is represented in the buoy col- 
lections by a single specimen of Cirolana parva. This species has 
previously been reported from many tropical localities including: 
Georgia (Menzies and Frankenberg, 1966); Florida, Gulf of Mexico, 
West Indies, and the Bahamas (Richardson, 1905b); Jamaica (Rich- 
ardson, 1912); Cameroon and South Africa (Monod, 1931a, 1933); 
Mozambique (Barnard, 1914); Red Sea and Suez Canal (Stebbing, 
1910; Monod, 1931 and 1933) ; Ceylon (Stebbing, 1905) ; Siam (Chilton, 
1926); Polynesia: Rikitea (Nobili, 1907), Samoa (Hansen, 1890); 
Indonesia: Timov, Aru, et al. (Nierstrasz, 1931). The present report 
of this species in the Hawaiian Islands extends its distribution into 
the central Pacific. The author also has collected it from reefs around
