The new name is given in honour of Dr. Kaburaki, who has 
enriched our knowledge of Stylochidae with a series of new forms. 
The genus Cryptophallus in known from Port Natal in West Africa 
and the Malayan Archipelago, while the new genus is a member 
of the temperate Pacific fauna of North America. 
I may here add that the same species is represented by several 
specimens in my collections obtained in Puget Sound at Seattle, 
and courteously presented to me by Professor Trevor Kincaid, A. 
M., University of Washington, during my visit there. 
The new genus I give the following diagnosis: Rounded or oval 
Stylochids with a large, very consistent, and thick body with thin 
edges. Tentacles long, retractable into sheaths. Marginal eyes around 
the whole body; no frontal eyes; cerebral eyes in two clusters; 
in the interior of tentacles and below them an extreme number of 
eyes. Mouth in the second third of the body. Pharynx, extremely 
folded, and very deep, sometimes bi-lobed pharyngeal side-pockets. 
Non-anastomosing intestinal coeca. Male and female pores rather 
close to each other, farther away from hinder margin of body. 
Male apparatus at well-marked distance behind the pharyngeal 
pocket, with false seminal vesicles, chambered, backwards directed 
vesicula granulorum, and unarmed, vertical penis without penis- 
sheath. Ductus vaginalis opening to the exterior at the border of 
female gonopore. 
Enterogonia pigrans Haswell 1907, var. novae-zealandiæ n. var. 
vPlate III, Fig. 17. Plate IV, Figs. 24, 31 and 32). 
Locality: Ponui Island, Auckland, New Zealand. Undernealh 
stones on the beach. 
Material: Four specimens obtained December 24, 1914, and 
preserved in formalin. 
In his important paper on Australian Polyclads, Professor Has¬ 
well (1907 b) has briefly described a Polyclad which very likely 
represents the same species as the present specimens. I will dis- 
cuss the question of identification at length below. It may be 
mentioned he<re that at first I was in doubts as regards the locality
