In the last volume of the Monographia, Pfeiffer gives the 

 locality Juan Fernandez, and this has been confirmed by E. 

 A. Smith. It is highly improbable that the same species oc- 

 curs 'in 'both of the islands mentioned. The figure is from 

 Kuester. 



The original description of T. clausa follows : 

 "Tornatettina clausa Beck, p. 80. Strobilus bftamett&tus 

 Ant., p. 46. Shell ovate-conic, pellucid, corneous, very thin, 

 striolate ; whorls 6, flat, the last shorter than the spire ; aper- 

 ture oblique, oval; peristome simple. Length 5%, diam. 3 

 mill. Opara ( Anton). " (Pfr., 1842.) 



2. T. HIDALGOI Crosse. PL 33, figs. 7, 9. 



Shell imperforate, oblong-conic, thin, a little shining, pel- 

 lucid, chestnut-corneous. Spire rather long, the apex a little 

 obtuse, rounded. Whorls 6, slightly convex, slightly striatu- 

 late obliquely, nearly smooth, the last whorl a little shorter 

 than the spire, rotund, tapering at base. Aperture somewhat 

 oblique, semioval, obstructed by a large, spirally directed, 

 deeply entering, white parietal lamella. Columellar margin 

 thickened within, white, having a strong white somewhat ir- 

 regular fold. Outer lip simple, acute; palatal wall armed 

 with two deeply placed white teeth joined by a callus. Length 

 4y 2 to 5, diam. 2 mm. (Crosse).

Tornatellina hidalgoi CROSSE, Journ. de Conchyl., xiii, 1865, 

 p. 219, pi. 6, f . 6. PFR., Monogr., vi, 266. GARRETT, Proc. A. 

 N. S. Phila., 1879, p. 25, last paragraph. 



Somewhat related to T. perplexa Garrett, but decidedly 

 larger, with the columellar armature somewhat different. It 

 is probably closely related to T. bilamellata. Garrett remarks 

 that specimens from the Gambier Is. in his possession have 

 two palatal teeth like Crosse 's type, "or have simply from one 

 to two spiral rows of denticles in the palate."
