given in the third line, somewhat approach 8. virgata; but differ from it in the 
wrinkled sculpture and dull coloration, without distinct rays on the last whorl. 
One example approaches in its measurements and general form the var. subtilis, but 
differs from it in the wrinkled surface.

Amber-coloured, with several whitish rays, rather solid, inside of the same colour as the outside; the propor-

and Tehuacan (Hége).

Var. hégeana, n. (Tab. XIX. fig. 5.)

occupied by the aperture.

Also of larger size, and with the whitish rays less conspicuous ; but with shorter spire, the aperture occupying 
4 of the whole length. 
Long. 15, diam. 9; apert. long. 11, lat. 7 millim, 
Hab. Central Mexico: Puebla (Boucard *). 
The specimen from Paso del Macho, quoted above, in its more ventricose form 
approaches this variety, but it is much smaller.

gardens (Morelet }~°).

In the comparatively long spire and the strong convexity of the penultimate whorl 
this species approaches the European S. oblonga, Drap.
