H. (Pseudocampylcea*) testacea MTS., t. c., p. 194, t. 10, f. 6. 



Most nearly allied to H. pellita, but larger, without hairs when 

 grown, more globular, coarsely striated and somewhat granulated, 

 brownish yellow, with a light band at the periphery between two 

 darker narrow bands, the lower one more variable, sometimes hardly 

 indicated. Young examples show short hairs, as in pellita; and 

 when quite young it is carinated. This species may be one of the 

 forms included by Ferussac in his H. naxientia=naxiana.

The relationships of this group are still unknown. It may prove 

 to be entirely distinct from the genus Helix, in which I consider it 

 best to locate it for the present. 



H. PILISPARSA Martens. Unfigured. 



Similar to H. gabata Gld., but the three upper whorls do not rise 

 one above another ; the color is pale greenish-gray, the suture 

 marked with a chestnut-brown band, the keel of the last whorl of 

 the same color as the rest of the shell ; reflected part of the peris- 

 tome about 2 mill, broad; umbilicus having more sloping walls. 

 Surface beset with short hairlets above and below. 



Alt. 10, diam. 23 mill.
