4. NoTOPLiTES AVICULABI^ {Yanagi 4" Okada). 
Scrupocellaria avicularice, Yanagi & Okada, 1918, Ann. Zool. Japon. ix. p. 413, pi. vi. 
fig. 4, text-fig. 4. Japan, 78 fathoms. 
Scutum large, with a complicated cavity. Frontal and marginal avicu- 
laria small. Basal avicularia small, the rostrum directed obliquely proximally 
and inwards, not confined to the bifurcations, but occurring alternately, on 
the proximal ends of the zooecia. The text-figure shows clearly the origin of 
a rootlet from a basal avicularium.

Jullien and Waters both pointed out in the same year (1888) that Busk's 
species is a synonym of S. marsupiata. A special peculiarity of the species is 
that the convex scutum so completely fills the opesia that it appears at first 
sight to be the frontal wall. It is attached to its stalk at the distal inner 
corner, and its free border is marked by characteristic radial slits, in the 
' Challenger ' specimen (87.12.9.83) at least. Frontal and marginal avicu- 
laria small. Jullien states that he found a single basal vibraoulum in this 
species, and Waters points out that Kirkpatrick has found vibracala on the 
basal side, on two zooecia. 
(b) Species in ivliich basal avicularia are not recorded. 
6. NOTOPLITES ELONGATUS {Busk). 
Cellularia elongata, Busk, 1884, p. 19, pi. 3. figs. 3-3 b. Kerguelen, 28 fathoms. 
Scutum elongated, the distal lobe the smaller. The ' Challenger ' slides 
(87.12.9.65, 66) show that this species agrees in its bifurcation with Noto- 
plites. Marginal avicularia small, frontal avicularia wanting. I cannot find 
any case in which two median zooecia occur, as shown in Busk^s fig. 3 a. 
7. NoTOPLiTES JEFEEEYSII (Nomian).

In his 1893 paper Norman pointed out that the scutum is not correctly 
described in his original account and in Hincks' fig. 1, also referring to the 
* The figures are wrongly given in the text as 3-5, as pointed out by Norman (1903, p. 446).
