DRYMJEUS, SOUTH AMERICAN. 207 



Bulimulus germaini ANCEY, Journal of Conchology, vii, p. 91 

 <July, 1892). 



A single specimen was found. It is somewhat like a small, thin 

 B.feliv, but otherwise quite distinct from the New Granada shell 



D. VIOLACEUS (Mousson). PI. 35, figs. 30. 31 (typical), 26, 27, 28, 

 29, 32. 



Shell broadly rimate-umbilicate, ovate-oblong, moderately solid ; 

 yellowish or faintly brown tinted, typically with longitudinal slightly 

 irregular gray or purplish-brown streaks, which are lineolate with 

 fine yellow or whitish vermiculate lines (but in other specimens the 

 streaks are acutely festooned or otherwise irregular) ; shining, with 

 slight growth wrinkles, more or less fine malleation, and minute 

 incised spiral striation. Spire high-conic, the apex white or buff 

 and typically sculptured. Whorls 6J, slightly convex, the last 

 ascending in front, more or less strongly compressed below the peri- 

 phery, sloping flatly to a prominent, obtuse basal keel; excavated be- 

 hind the coiuinellar lip. Suture but little impressed. 



Aperture half the length of shell or more, subvertical, whitish 

 and showing the external bands by transparence within, becoming 

 deep lilac (or "intense reddish -violet ") toward the lip ; peristome 

 very broadly expanded, reflexed, lilac with a white edge ; columellar 

 margin flaring, impressed and slightly grooved at its root, the outer 

 edge nearly straight and obliquely sloping; columella with a con- 

 vex fold far above, then concave in the middle or nearly straight, 

 often convex again at base, or with an oblique tubercle there. 



Alt. 37$, diam.19 ; alt. of aperture 21 mill. 



Alt. 40, diam. 19* ; alt. of aperture 20 mill. 



Alt. 36J, diam. 17? ; alt. of aperture 20 mill. 



Alt. 39, diam. 19 mill. (Mousson for violaceus), 



Alt. 44, diam. 20 mill. (Mousson for eversus).

Balimiis violaceus Mouss., Malak. Bl., xxi, 1873, p. 9. PFR., 

 Novit. Conch., iv, p. 134, pi. 130, f, 5, 6. Bulimus eversus Mouss., 

 I.e., p. 10. PFR., I.e., p. 136, pi. 130, f. 9, 10; Monogr., viii, p. 50. 



Especially notable for the strong, blunt basal keel, the whorl 

 being flattened and tapering around it, and the umbilical region 

 -excavated and large. The broadly flaring lip is white at the edge, 

 but becomes deep lilac within, but the parietal wall retains the color 

 of the exterior, bearing a mere transparent film.
