5. E. PEASEANUM (Garrett). PL 31, fig. 5. 



"Shell imperf orate, oblong-ovate, smooth, thin, shining, 

 faintly striated, dark brownish horn-color; spire conical, with 

 nearly planulate outlines and subacute apex; suture faintly 

 impressed ; whorls five and a half, convex, moderately increas- 

 ing, last one large, rounded, not descending in front ; aperture 

 large, oblique, truncately ovate, nearly half the length of the 

 shell; peristorne thin, straight, regularly curved; parietal re- 

 gion with a prominent, thin, revolving white lamina, which 

 is slightly reflected posteriorly ; columella armed with a promi- 

 nent, nearly vertical, bidentate plait. Length 5, diam. 2~y 2 

 mm." (Garrett). 



Society Is. : Moorea Island, very rare on foliage (Garrett). 



Tornatellina peasana GARRETT, Journal of the Acad. Nat. 

 Sciences of Phila., 2d ser., ix, p. 83, pi. 2, f. 19, 1883. 



"Closely allied to aperta, but much larger more elongate, 

 darker color and the spire more produced." The tapering 

 summit and subacute apex are further distinctions from 

 apertum, which has a far more obtuse apex. Garrett 's figured 

 type, is redrawn in our plate. The number of \vhorls is 

 wrongly given by Garrett. There are 4i/ in the type-speci- 

 men, which measures, length 4.9, oblique diam. 2.7 mm. 



Species of Australia, New Guinea and New Caledonia. 



Critical comparisons will probably reduce the number of 

 species recorded from this area. 



6. E. WAKEFIELDLE (Cox). PI. 30, figs. 9, 10. 



"Shell imperf orate, ovately-conical, very thin, translucent, 

 rather shining, smooth, microscopically striated, yellowish- 

 horny; spire conical, obtuse at the apex; whorls 4, slightly 

 convex, last large, tumid, equaling one-half of the length ; 

 aperture irregularly ovate, with a very thin central, vertical, 

 parietal plate ; columella thinly expanded and revolute in- 

 wards, grooved above; peristome simple, acute. 



Length 0.10, breadth 0.07, aperture 0.05 long, of an inch"
