164 TORNATELIJNA. 



almost straight (fig. 9) to distinctly though slightly sinuous 

 (fig. 5). Rarely one may see one or two low callous streaks 

 within the palatal wall, but they are not at regular intervals. 

 No individuals in the early neanic stage have been examined 

 from Polynesia, so that the presence of well-developed palatal 

 ribs, such as are found in Hawaiian examples, could not be 

 verified. There are none in the middle or late neanic stages. 



Specimens of this species taken by the junior author on 

 Palmyra Island are identical with those collected by Garrett 

 on the Society Islands and also with others from the Hawaiian 

 Islands. 



We agree with Garrett that T. bacillaris Mouss., described 

 from Futuna, Tonga Is., is identical with T. oblonga, with 

 which the description agrees in all respects. The original fig- 

 ure of bacillari'S is copied, pi. 36, fig. 8.

1 ' Shell minute, thin, lucid, fragile ; conically ovate ; whorls 

 five, convex; aperture small, ovate, less than one-half the 

 length of the shell ; a spiral lamella on the columellar lip and 

 one at the base ; last whorl furnished with three longitudinal 

 lamellae, extending its whole length and disposed at equal dis- 

 tances from the outer lip, at about one-sixth of the circum- 

 ference of the whorl apart; edges of the lamellae serrated"

Marshall Is.: Ebon Island (Garrett, type loc.). Cook's or 

 Hervey Is. : not uncommon in the lowland forests near the sea- 

 shore, and ranges throughout the group (Garrett). 



Austral Is.: Eurutu (De Gage). Society Is.: Huaheine, 

 Tahiti, etc., adhering to the under side of loose stones, dead 

 wood, among decayed leaves, and sometimes on the leaves of 

 low bushes (Garrett). Kingsmill Is. (Pease collection).
