NEW SNAILS—PARODIZ 437 
and ends at the middle of the outer lip. Protoconch with the fine 
pitted structure of Drymaeus. The first four whorls white roseate; 
in the third whorl a median chestnut spiral band is initiated; another 
chestnut band comes out from the superior angle of the aperture and 
runs a little below the carina: a third band covers the umbilical zone 
from the supracolumellar end of the aperture to the basal lip; these 
three bands are connected with another of the same color which forms 
a dark and broad margin on the outer side of the lip and leaves only a 
narrow white zone of a half mm. along the edge. Numerous axial 
oblique bands, clearer in color than the spirals, are present in the last 
whorl (about 29 in number) separated by very variable spaces; at the 
points where these axial bands meet the carina, a darker spot is pro- 
duced, and the carina is, therefore, marked with a spotted spiral line. 
The rest of the surface of the last whorl is cream or ivory white. 
Aperture oval, wide in the base; columella almost straight, white; 
peristome simple; the interior of the aperture is well marked with the 
spiral bands, but the axials are seen only by transmitted light. The 
surface of the shell is smooth, marked only with the growth lines and 
without the microscopical spiral lines we find in D. poecilus. 
Holotype (USNM 609317) from Peru (The specimen was in a lot 
with two specimens of D. poecilus). Measurements of holotype: 
Height 23.2 mm., larger diameter 11.5 mm., lesser diameter, 10 mm., 
last whorl 17.7 mm., penult. whorl 3.8 mm., aperture 12x7 mm. 
The specimen is a perfect, well-developed adult, not a young of 
poecilus, as one might think from its carination; the carination is 
indeed a peculiar feature of the species, which is also very distinct in 
its color pattern and proportions; I have examined several hundred 
specimens of D. poecilus presenting all kinds of subspecific and 
individual variations, and from all of them this specimen is remarkably 
different. It also resembles D. multilineatus (Say), but besides its 
distinct geographical range, multilineatus is a more elongated species 
with a dark subsutural but no median band, is not carinated, and its 
whorls are more convex. 
The species is dedicated to my friend the distinguished zoologist, 
Dr. Waldo L. Schmitt, formerly Head Curator of Zoology at the U.S. 
National Museum.

If the locality ‘“Uruguay’? (USNM 530524, coll. Chamberlain) 
is correct, the southern limit of this species is greatly extended.
