Grateloup's figure shows a badly worn and decorticated specimen, 

 which I can match with some material from the Lake Naujan region. 

 The race about this lake has the short, rounded base and is smaller 

 than typical aspersa to the north of this region. I am, therefore, 

 reserving Grateloup's name for this race. 



Thirty specimens (U.S.N.M. no. 313711), collected by Worcester 

 and Bourns on the Menage Expedition about Lake Naujan, yield the 

 data given in the foregoing table. 



The specimen described and figured (U.S.N.M. no. 313710) wa9 

 collected by Worcester and Bourns on the Menage Expedition. It has 

 5.9 whorls and measures: Length, 59.9 mm; greater diameter, 30 mm; 

 lesser diameter, 24.5 mm.

 Sci., vol. 22, p. 342. 



Shell elongate-ovate. The base of the last whorl is considerably 

 protracted and gently rounded. Early whorls are chocolate-brown 

 with a purplish tinge; the middle whorl is buff, and the last chestnut- 

 brown. The whorls are marked by retractively slanting bands of 

 yellowish buff, which may be fulgurated, broken, or more or less com- 

 plete, though alternating with zones of the ground color of the shell. 

 Interior of the aperture pale bluish; peristome with a chocolate-brown 

 outer edge, the inner portion of the peristome fading into the color of 

 the aperture, both on the outer lip and the columella. Nuclear whorls 

 3, the first smooth, the rest grading into the sculpture of the post- 

 nuclear whorls, which consists of irregular, retractively curved, incre- 

 mental lines. The usual crisscross microscopic sculpture is well pro- 

 nounced on both spire and base. The postnuclear whorls are appressed 

 at the summit and moderately well rounded. The periphery is also 

 rounded and the protracted base gently so. Aperture broadly oval; 

 outer lip broadly expanded and reflected, the inner lip likewise ex- 

 panded and reflected, particularly at its insertion, where it almost 

 covers the umbilicus. The parietal wall is covered by a rather stout 

 callus. 



The type (U.S.N.M. no. 313712) was collected by Col. Edgar A. 

 Mearns on the Mount Halcon Expedition. It has 6 whorls and meas- 

 ures: Length, 66.2 mm, greater diameter, 32 mm; lesser diameter, 28.2 

 mm. 



Eight topotypes (U.S.N.M. no. 255799) yield the following addi- 

 tional measurements:
