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 Teredinidse 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 Sarsf is great enough to include 

 the form before me.

(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 3 mm. 



Pedicle valve deep, hinge line straight, 

 cardinal area triangular, apex rather re-

 arising from a deep seated septum. 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.
