NEW SNAILS—PARODIZ 435 
All the other specimens (in USNM, MCZ, and in the Hylton Scott 
Collection) are from Jujuy. 
The protoconch is typically that of Bulimulus s.s., but sometimes 
it has characters transitional with Scansicochlea. 
Genus Drymaeus Albers, 1850 
Drymaeus rehderi, new species 
PuaTE 1, Ficurss 5, 8 
Shell widely rimate umbilicate, ovate conic, rather solid; white, 
shining except the first 1% whorls which are dirty yellow; in the last 
whorl are some obscure, very inconspicuous vertical spots. Six 
whorls comprise the last three-fifths of the total length; the width 
of these whorls is more than three-fourths of the total length. Sur- 
face apparently smooth, but with fine and regular marked growth 
striae. Suture somewhat marginate and at its end, near the lip, 
crenulated and curved upward, so that the spire is excessively inclined 
in a profile view when the lip is in a vertical position and the penulti- 
mate whorl appears immersed into the last whorl; the crenulations 
of the suture are formed by the aggregation of five or more lines of 
growth; a low keel at the base of the last whorl corresponds to a sinus 
on the left base of the peristome. The columellar lip has a margin 
in the form of an elongated S; the inside of the lip is lilac tinted and 
becomes more violaceous on the columella; a white margin, about 1.5 
mm., lies between the violaceous strip and the edge of the lip; the 
peristome is well expanded. 
Holotype: USNM 590653, Valdivia, Antioquia, Colombia, at 4500 
feet on the Cordillera Oriental, collected by M. A. Carriker, June 1948. 
It measures: Height 37 mm., diameter 22 mm., last whorl 24.5 mm., 
penultimate whorl 6 mm., aperture 20.5x16 mm. 
This beautiful new species is related to Drymaeus glaucostomus 
Albers, but that species has three blackish bands, a suture not crenu- 
lated nor margined, and straight columella, and is a smaller size. 
D. fairchildi Bequaert seems to be another close species, but it is 
entirely white within the aperture, is carinate in the middle of last 
whorl, and has a simple peristome. 
I have the pleasure to name this species in honor of Dr. Harald A. 
Rehder, Curator of Mollusks at the U.S. National Museum. 
Drymaeus megastomus, new species 
PLATE 1, FiGuRE 7 
Shell large with short spire, narrowly perforated, rather thin and 
transluscent. Five and a half whorls, the first very flat and the 
following increasing rapidly, the last being extraordinarily developed, 
equal to a little more than two-thirds length, and its diameter more
