CALLIOSTOMA-PUTZEYSIA. 413 



t'he last is acutely angular, the base level, curving into the um- 

 bilicus. The sculpture both above and below consists of 7 scarcely 

 elevated spirals, a little narrower than their interstices ; the latter 

 are prettily crispate with lines of growth. The aperture is nearly 

 circular, angled on the lower outer part, peristorae continuous. The 

 Jbase is usually unicolored green ; the umbilicus white, perforating.

Subgenus PUTZEYSIA Sulliotti. 



Putzeysia SUL., Bull. Soc. Mai. Ital. 1889, p. 30. Type, Tr. 

 clatliratus Arad. 



I do not know the systematic position of this group. Sulliotti says 

 that Tr. gemmulatus does not belong to the same subgenus as Tr. 

 .clatliratus, but I am inclined to believe that it does. 



P. CLATHRATA Aradas. 



Shell orbicu late-conoid, imperforate, solid, whorls convex, planu- 

 late at the sutures and subcanaliculate, clathrate with longitudinal 

 and transverse elevated equidistant lines, forming slight tubercles at 

 their intersections ; aperture suborbicular, lip subthickened.

A fossil species, lately dredged at the above locality. I have 

 translated Sulliotti's diagnosis. 



P. WISERI Calacara. PI. 57, fig. 43. 



Shell small, subconic, the 6-7 whorls more or less convex, latticed 

 by transverse cinguli (6 on penultimate whorl), and longitudinal 

 elevated, oblique lines ; aperture suborbicular ; lip sulcate within.
