D'Orbigny describes this shell as " albida," and as inhabiting the "sable vascux, 

 iiu niveaii des mare'es liasses'' at San Bias, north of Patagonia. This may account for 

 the pale brownish tint of his tv[ies in the British Museum, which have the appearance 

 of being mud-stained. Beyond being much whiter the shells m the present collection 

 agree in all other respects. Dlplodonta brasiliensis, Mittrc (1S;")()), Lucina janeiroensis,

 appear to belong to the same species, but differ in form from />. patagonica. They are 

 all recorded from Brazil, excepting xiil>t/l<>l><i>i. said to be West Indian.

Station 42, off llio de Janeiro : 40 fathoms. Off Cape Saint-Thome', Brazil, at a 

 depth of 80 metres (d'Orbigny). 



This species appears to have been overlooked in the monographs by Sowerby * and 

 Romer.f and was merely noticed by Bertin as non-existent in the Paris ^Museum. It is 

 of ii very elongate form, rounded at the anterior end, and pointed at the other 

 extremitv. The right valve has two divergent cardinal teeth, of which the hinder 

 one is bifid. The laterals are slender, that on the anterior side, slightly divergent 

 from the dorsal margin, is connected above with the oblique anterior cardinal. 

 The posterior tooth is more remote and passes into the nymph which supports 

 tin- ligament. The anterior of the two cardinals in the left valve is thick, 

 triangular, and bifid : the posterior slender and inclined backwards. The anterior 

 adductor-scar is pyrifonn, the posterior rounder. The pallia! sinus is verv deep 

 and extends almost across three-fourths of the shell, which is pure white within 

 and without. 



Several odd valves were obtained bv the "Terra Nova, the largest being 

 36 mm. in length and Ifi in height.
