(spec. 6) concerning the nematocysts of the acontia, and all nemato- 
cysts showed a good agreement concerning the size, as appears from 
the following table.

Remarks. I have with hesitation identified this species with 
Stuckey’s Sagartia vagrans, principally on account of Stuckey’s 
statement that the whole body-wall has (more or less) the character 
of a diffuse mesogloeal sphincter. 
Thoe neozelanica n. sp. 
Di agn osi s. Sphincter strong, in its upper part occupying al¬ 
most the whole breadth of the mesogloea, reticular-alveolar with 
tendency to stratification. Tentacles some 60. 2 well developed 
siphonoglyphes. Mesenteries pentamerously arranged (always?). 
About 10 pairs perfect with strong, diffuse longitudinal muscle 
pennons, the folds of which are high and somewhat ramificated. 
Parietobasilar muscles weak. Imperfect mesenteries without pen¬ 
nons, the stronger of them with filaments. Nematocysts of the 
tentacles 17 — 22 x about almost 2 — ( 2 , 5 ) /li, those of the acontia 
partly 41—50 x 5 — 6 /r, partly 19 — 24 x about 1 — I.5//, the latter 
needle-shaped.

Dimensions. Breadth of the pedal disc 0,45 — 0,3 cm, height 
of the column 0,2 cm. 
Occurrence. North Channel, Kawai Island, Hauraki Gulf 
10 fms. Hard bottom. 29.12.1914. 1 specimen. 
Exterior aspect. The small, not sexually ripe specimen has 
a broad pedal disc. The column is smooth. The distribution of the 
ciriclides I have not been able to confirm, but 1 have observed such 
on sections in the height of the aboral end of the actinopharynx. 
The tentacles were some 60, the inner considerably longer than 
the outer. The actinopharynx was very much folded and provided 
with 2 well developed siphonoglyphes.
