NEW SNAILS—PARODIZ 445 
Pilsbry referred to his figure (pl. 51, fig. 6) as being taken from the 
“Conchologia iconica,’”’ but it is not the Reeve figure. The original 
reference that Barattini gave is: “‘Drymaeus litus Reeve 1843, page 
236’’; Reeve did not use the generic name Drymaeus, which was 
created by Albers in 1850; there is no litus Reeve; the year of Reeve’s 
publication is 1849, not 1843; and “page 236” is correctly ‘figure 236.” 
This shows that Barattini knew only Pilsbry’s references, even when 
he said that ‘‘the species of Reeve is according to the specimens from 
Uruguay.” In addition, Formica Corsi’s figure of “‘ Bulimulus spora- 
dicus”’ (Anales Mus. Nac. Montevideo, vol. 2, p. 408, fig. 28, 1900) 
is Drymaeus papyraceus. 
Drymaeus elongatus Roeding 
Helix elongata Roeding, Mus. Boltenianum, Hamburg, p. 107, no. 1371, 1798 
(named for the specimen in Chemnitz, Neues systematisches Conchylien- 
Cabinet, vol. 9, fig. 1225a). 
Drymaeus elongatus, Pilsbry, Manual of conchology, vol. 12, p. 23, pl. 11, figs. 
1-26, 1899. 
Type locality: Unknown. The typical specimens are from Puerto 
Rico. 
One specimen (USNM 133603) from Nicaragua has been identified 
provisionally as belonging to this species. All other known specimens of 
elongatus are from Puerto Rico and the Lesser Antilles to Curagao; 
this is the first recorded for continental Central America, but it needs 
further confirmation. The structure of the protoconch indicates that 
it belongs to the subgenus Levostracus. 
Genus Protoglyptus Pilsbry 1897 
Subgenus Rimatula Parodiz 1946 
Protoglyptus (Rimatula) minutissimus, new species 
Shell very small and narrowly rimate, more than three times longer 
than wide, the upper half almost conic and lower half oblong; rather 
solid but translucent, of corneous appearance. Shell composed of 
6% whorls, the last almost 60 percent of the total length, regularly 
convex with a well-impressed, somewhat crenulated suture. Surface 
horn colored, crossed by oblique white incremental lines variable in 
width, which are more evident in the last two whorls; under the micro- 
scope the surface shows a few very fine spiral lines, especially around 
the umbilical and sutural areas. Umbilical rimation covered by an 
expansion of the peristome. Aperture ovate, angulated at the superior 
end and at the base; one-fifth as wide as the total length of the shell; 
peristome simple, not reflected but rather thick on the columellar side.
