harpacticoid frequents the shallow waters along shore and is very 
widely distributed. It is a bottom form and would not be captured 
except at anchorages and in harbors and so does not appear in any of 
the plankton lists. Both of these Adbatross localities are in the 
Pacific, one far to the north and the other in the Philippine Islands. 
Genus HEMIRHABDUS Wolfenden, 1911 
HEMIRHABDUS GRIMALDII (Richard) 
Heterochaeta grimaldii RicHarD, Bull. Soc. Zool. France, vol. 18, p. 151, 1898. 
Stations 46638; 4715; 4721; 4724; 5120; 5185. Five females and a 
male were identified by Sars from the first four, eastern Pacific, sta- 
tions. It was present at 17 Monaco stations but not in the other plank- 
tons. It was first reported from the Pacific area by Sewell (1913, p. 
354; 1982, p. 304). 
HEMIRHABDUS LATUS (Sars) 
Heterorhaddus latus Sars, Bull. Mus. Océanogr. Monaco, No. 40, p. 9, 1905b. 
Hemirhabdus latus Sars, Rés. camp. sci. Albert de Monaco, No. 69, p. 232, pl. 
64, 1925. 
Stations 4719; 4722. Identified by Sars from these two Albatross 
stations between the Galapagos and Paumotu Islands and from four 
Monaco stations. [It is suggested by Sewell (1932, p. 306) that 
this species is a synonym of Z. truncatus (A. Scott).] 
Genus HETERAMALLA Sars, 1907 
HETERAMALLA DUBIA (T. Scott) 
Amallophora dubia T. Scort, Trans. Linn. Soc. London, ser. 2, Zool., vol. 6, Ry al 
p. 55, pl. 4, figs. 1-18, 1894. 
Station 3799. Scott’s original specimens came from the Gulf of 
Guinea and were placed in the genus Amallophora, but Sars created 
the new genus above for their reception and fully described them in 
the Monaco plankton. The species was also present in the Siboga 
plankton and has been reported from the Pacific in the Carnegie 
list. 
Genus HETEROPTILUS Sars, 1920 
HETEROPTILUS ACUTILOBUS (Sara) 
Pontoptilus acutilobus Sars, Bull. Mus. Océanogr. Monaco, No. 40, p. 21, 1905b. 
Heteroptilus acutilobus Sars, Rés. camp. sci. Albert de Monaco, No. 69, p. 328, 
pl. 117, 1925. 
Station 4671. Identified by Sars from this single Albatross sta- 
tion off the coast of Peru and from 10 Monaco stations but not in the 
other planktons. In fact, this is the first record since the original 
discovery and hence of course the first from the Pacific Ocean.
