12. NOTOPLITES VANHOFFBNI {Kluge). 
Scrupocellaria vanhoffeni, Kluge, 1914, p. 610, pi. 27. fig. 6. Antarctic, 3.50-385 
metres. 
Frontal and marginal avicularia and scutum present ; differing from the 
preceding species in the scutum, which has a complicated or " cervicoi'n " 
cavity. Bifurcation figured. 
13. NOTOPLITES WATERSI {Kluge). 
Scrupocellaria watersi, Kluge, 1914, p. 60", pi. 27. fig. 2. Antarctic, 350-385- 
metres. 
Frontal and marginal avicularia and scutum present. The bifurcation 
represented in the figure is typical except for the zocEcium B. I suspect 
that a mistake was made with regard to this point. 
14. ? NOTOPLITES PERDITUS (KllU/e). 
Scrupocellaria perdita, Kluge, p. 613, text-lig. 2. Antarctic, 2450 metres, 
Bifurcation not described. The scutum and ovicell resemble the corre- 
sponding parts in iV. rostratus. 
Incertce sedis (possibly belonging to Notoplites). 
15. Menipea noemani, Nordgaard, 1900, Norske Nordhavs-Exp., p. 4, pl.i.. 
figs. 2-8. Ofi" Norway, 408-1134 metres. 
16. ? Notoplites simplex {Kluge). 
Scrupocellaria simplex, Kluge, 1914, p. 607, pi. 27. fig. 1. Antarctic, 385 metres. 
Branches biserial, the opesia elongated, oval, with much raised margin. 
Scutum and spines wanting. A single frontal avicularium, and occasionally 
a minute marginal avicularium. Ovicells unknown, basal heterozooecia not 
described. Bootlets at first passing down the margins of the branches, given 
oft from a chamber at the proximal end of the zocecium. Kluge states that 
this species is ordinarily unjointed, but that the branches may be jointed 
" oberhalb der Gabelung." The zooscium and the opesia resemble the corre- 
sponding parts of Notoplites elongatus (Busk) ; and it seems possible that the 
species should be referred to the same genus.

Zoarium jointed, the branches biserial. Internodes commonly constituted 
by three zoceciri, at least in the main stems. Zocecia more elongated than in 
Emma, the opesia occupying a small proportion of the front and without a
