556 Mr, A. Hempel on Brazilian Coccidee. 
characteristic is the delicate pale pink blotching round the 
margins, both ventral and anterior, internally ; the pallial 
sinus is large, extending almost to the centre of the interior. 
A specimen identical with those from Aden has been 
dredged off the Mekran coast of Baluchistan, not very far 
from Karachi, by Mr. F. W. Townsend, and I purpose 
figuring this, as it is so much the largest, in company with 
one of Commander Shopland’s types. 
It is important that no confusion should exist between 
Cumingia tamellosa, Sowb., 18338, from Chili, and C. (Thyella) 
lamellosa, H. Ad. (= Cumingia elegans, Sowb.), from the 
BKastern Archipelago and Australia. In this latter the lateral 
teeth are absent in either valve. 
Calyptrea (Galerus) Edgariana, Melv.* (PI. UX. figs. 8, 
8 a).—It is necessary to refigure this, the former delineation 
not having been very successful. ‘This species has since been 
found by Mr. ‘Townsend near Bushire and Maskat.

Genus CEROPLASTES, Gray. 
Ceroplastes amazonicus, Hempel. 
Adult female scale very convex, oval, with the lower 
lateral edges much produced. ‘The anterior end is jointed and 
slightly produced; the posterior edge is slightly notched ; 
the dorsum is obliquely truncated and slightly concave, the 
wax being a little higher behind than in front. The colour 
is dirty white, with a brownish tinge on the posterior portion.
