OPEAS GRACILE. 131 



reported from Funafuti, the Marshall and the Caroline 

 Islands. 



The shells before me are all smaller than typical gracile. 

 In most of them the suture is finely but distinctly denticu- 

 late in places, chiefly in the upper half of the shell. I have 

 figured a shell from Tahiti, pi. 22, fig. 4, nine mm. long with 

 over 7 whorls and nearly smooth suture, and a more slender 

 Samoan shell, pi. 22, fig. 11, received from Schmeltz as 

 "upolensis Mouss." It is 8.8 mm. long, with 7% whorls. 



Bulimus junceus Gld. was based upon the small Polynesian 

 race of gracile. The description follows, with a copy of 

 the original figure. 



B. junceus Gld. (pi. 22, fig. 6). " Shell small, thin, trans- 

 lucid, elongated, turreted, of a pale green color, obtuse at 

 apex, covered with delicate longitudinal striae. Whorls seven, 

 slightly convex, presenting a broad shoulder above. Aper- 

 ture long ovate : lip simple, on the left slightly reflected over 

 a minute umbilical chink : the last whorl about one-third the 

 length of the whole shell. Length of axis three-tenths of an 

 inch; breadth one-tenth of an inch (Gould). 



"Inhabits Tahiti and Eimeo. This shell very closely re- 

 sembles a West Indian species, and is, perhaps, the same, and 

 may be a denizen of the cocoanut or banana, wherever found. 

 B. bacterionides agrees in form, but this is not ' smoother than 

 octona,' and has not nine whorls. " (Gould.)
