tross stations and at 34 Monaco stations and found in the Siboga and

PAREUCHAETA TUMIDULA (Sars) 
Euchaeta tumidula Sars, Bull. Mus. Océanogr. Monaco, No. 26, p. 15, 1905a. 
Pareuchaeta tumidula Sars, Rés. camp. sci. Albert de Monaco, No. 69, p. 119, pl. 32, 
figs. 15-20, 1925. 
Stations 27; 4667; 4679; 5120; 5287; 5319. Identified by Sars at 
the first three Albatross and at five Monaco stations, and present in the 
Carnegie list. 
Genus PAROITHONA Farran, 1908 
PAROITHONA PARVULA Farran 
Paroithona parvula FarRAN, Fisheries Ireland, Sci. Invest. for 1906, pt. 2, p. 89, 
pl. 10, figs. 1-18, 1908. 
Stations 5382; 5437. Established by Farran upon females taken in 
deep water off the west coast of Ireland and described in Sars (1918, 
p. 208) Crustacea of Norway. Not found in any of the plankton lists. 
The male still remains unknown. 
Genus PENNELLA Oken, 1815 
PENNELLA sp. 
Station 5287. A single copepodid larva of some species of Pennella 
was taken in the tow at this station in the China Sea. A similar larva 
appears in the Challenger plankton and was named Hessella eylindri- 
cum by Brady. It is not, however, a matured adult but only a larva, 
and it swims about in the plankton until it finds a host to which it 
attaches itself and develops into some species of the parasitic genus 
Pennella. The larva cannot yet be specifically differentiated.

Phaénna spinifera CLaus, Die freilebenden Copepoden, p. 189, pl. 31, figs. 1-7,
