for birds, and was therefore inadmissible. He proposed to sub- 
stitute Bactronophorus, Tapparone Canefri (1877). As, however, 
the prior name of Nausitoria is available, that must come into 
use when Calobates is abandoned. 
The Teredinidze have been unfortunate in their monographers. 
The account in the last volume of the Conchologia Iconia, by 
Sowerby, is a slovenly production and full of errors. Even worse 
is an alleged Monograph by Clessin in the Conchylien Cabinet, 
of which the text and illustrations disgrace that serial. The 
latter memoir is absolutely the worst zoological monograph I have 
read,

A single valve was collected on the Funafuti beach, which I 
refer with doubt to this species. It is more oblong than the 
figure quoted, but as I have no authentic specimen for comparison, 
and as Dall credits this species with great variation*® in form and 
sculpture, I refrain from assigning specific value to the apparent 
difference. According to this writer, P. australis, Smith,; from 
Cape York, Queensland, is but a variety. The difference between 
this and such a figure as that of Sars} is great enough to include 
the form before me.

THECIDEA MAXILLA, Sp. nov. 
(Fig. 57). 
Shell small, of variable contour, somewhat boat shaped, attached 
to stones, shells, or the like, by the beak of the pedicle valve. 
Colour, dull pale yellow. Sculpture—both valves marked by 
delicate concentric growth lines and microscopically shagreened. 
Length of a large specimen, 6 mm. ; breadth 35 mm, 
Pedicle valve deep, hinge line straight, 
cardinal area triangular, apex rather re- 
curved, Marginfinely granulate, frequently 
emarginate in front. Protruding from be- 
neath the hinge are two slender prongs 
arisingfromadeepseatedseptum. External 
to these, and just beneath the hinge line, are 
two heavy, projecting, wedge-shaped car-

irregularly studded with sharp points and 
tubercles arranged longitudinally, and varying in different in- 
dividuals.
