of this shell at Tutuila, which was given to Mr. Pease, and never 

 returned. The example in the Coll. A. N. S., labeled " P. Brazieri 

 Pease ex auctore " is of the New Hebrides type and agrees with 

 my example of Turneri.

Obs. — Unlike other Partulae this species is devoid of emb^onic 

 fovea or spiral striae. The former are minute longitudinal 

 wrinkles, which are continued over the coarse longitudinal striae 

 of the surface. The aperture is of a reddish orange color, with 

 a large mammilliform tooth on the pillar lip, and a wide columella 

 above, together with an open umbilicus. The general facies is 

 that of a Placostylus, which induced Mr. C. F. Ancey to create 

 the subgenus Diplomorpha for the species. Mr. Layard having 

 sent me several of the animals in alcohol, they were referred to 

 Mr. Wm. G. Binne} r , and, notwithstanding the external differences, 

 " he finds the jaw, lingual dentition and genitalia like other 

 Partulae."
