 mm. 



Immature specimens have the parietal lamella stronger, and 

 there are two oblique columellar lamellae, the lower one 

 slightly larger (fig. 9).

T. ronaldi is a narrower, more lengthened shell, otherwise 

 closely related to this species, which was found in abundance 

 in the leaf-siftings. T. popouelensis is darker-colored than 

 Tornatellaria baldwiniana, the umbilicus is more widely open, 

 and it is viviparous. 



41. T. PYBAMIDATUS (Aiicey). PL 51, figs. 1, 2. 



"Shell conoid-turrite, thin, glossy, of a pleasing rufous- 

 corrieous, openly but minutely umbilicate, under a lens slightly 

 marked with growth-lines. Spire produced, long-conoid, the 

 apex a little obtuse. Whorls 6%-7, slowly increasing, separ- 

 ated by an impressed, very horizontal suture, convex, the last 

 whorl ovate, rather short, hardly dilated, tapering a little at 

 the base. Aperture small, irregularly oval, obliquely sub- 

 truncate above, nearly vertical, armed with a moderate com- 

 pressed parietal lamella. Columella swollen, dilated, un- 

 armed or obsoletely one-folded above. Peristome simple, the 

 columellar margin rather widely expanded. Length 2.66, 

 diam. 1.25, alt. apert. scarcely 1 mm." (Ancey). 



"In the young the columella is provided with two strong, 

 acute lamellae, the lower one larger" (Ancey).

" I see no species with which I could unite T. pyramidata, a 

 small, long shell recalling T. cylindrica Sykes and gracilis 

 Pease in general shape, though the spire is more regularly 

 pyramidal and conic. The parietal lamella is moderately
