MOELLENDORFF : LAND SHELLS OF CAROLINE ISLANDS. 



basi convexior. Apertura valde obliqua, ampla, late cordiformis, 

 peristoma rectum, acutum, margo columellaris pauUum dilatatus. 



Diam. maj. 4-5, min. 3'25, alt. 2 mm. 



Hah. — Naupilo on Ponape, at about 100 m. altitude (Kubary). 



When I received this curious little shell, I felt convinced that it 

 belonged to FlammuUna, but in order to make sure, I sent it to Mr. 

 Suter who sends me the following as the result of his investigations. 



" Flammuliva (s. str.) 7iujresre7i.-<, Mlldff, from Ponape, Carolines. 



"Two specimens, containing the dried-up animals, of this very in- 

 teresting mollusc were kindly sent to me by Dr. O. F. von Moellendorff, 

 suggesting that the species might prove to belong to FlamwnUna, as 

 it resembles very much some New Zealand species with ribbed whorls. 



"After immersion in dilute caustic potash the foot of one of the 

 specimens became wholly extended, and I was able to ascertain with 

 certainty the presence of a peripodial groove, a broad pallial margin, 

 and a caudal gland (fig. i).
