to have imany points of resemblance. In shape as well as in 

 sculpture it is very like ; only both ribs and spirals are much 

 stronger ; the mouth, too, is oval, but it is pointed above and is 

 longer below, iV". epTiamilla having a broader and more truncate 

 base. My estimate on all these points, however, is based on 

 Philippi's description and figure, the species itself being unknown 

 to me.

In the following group are several interesting forms, especially 

 some of the Siphos and To'ophons ; but of them all, probably the 

 most remarkable is one which, for the present, I have called 

 Fusus {Cohis) pagoddides. I have no doubt that in the long run 

 it, with the two species of Fusus wbich here precede it, and many 

 of the Trophons will be classed with the Fusus pagoda^ Less., 

 and the Fleurotoma spinicincta, v. Mart., for which last Prof. v. 

 Martens has lately proposed a subgenus {Columbarium), based 

 chiefly on tie radula. Of this organ Mr. Gr. Schacko describes 

 » and figures two very curious teeth, which were the only ones 

 ■ he was able to obtain from the dried-up specimen in his hands. 

 If I have not adopted Prof. v. Martens's classification here, it 

 is because his paper reached me only a very few days ago, and 

 time has not sufficed to consider the matter in all its bearings.
