Arctic Ocean. W". S. 



Like JV. clausa, but larger, the whorls more broadly shoul- 

 dered, the umbilical region more concave and more perfectly 

 closed by callus than in any shell of that species I have seen.

Resembles N. glabella and N. nitida. It is, however, more 

 elongated, and less flattened on the face.

Inhabits Hakodadi Bay, on shells, &c. W. S. 



Very delicate and slender, allied to G. planulata, a much 

 larger species, and G. strigosa, of which it may possibly be the 

 young. 



Vanicoro scalarina. T. ovato-globosa, tenuis, alba, costis 

 remotis elevatis imbricantibus lyrata et fills volventibus decus-

 3, ultimo magno ventricoso costis elevatis recumbentibus alter-
