AURIS-EUDOLICHOTIS. Ill 



Var. SUBL^VIS Pils. (pi. 40, fig. 30, from Arva, figs. 28, 29, from 

 Puerto Cabello, and fig. 27, from La Guayra) is constantly smaller 

 (alt. 34-42 mill.) and smoother; lip white or black-brown ; external 

 coloration creamy, cream and brown, or white and purplish, some 

 examples being boldly maculated. Form of aperture typical, or 

 with a callus buttress below outer end of columellar fold (fig. 27). 



Var GRACILIS Pils. (pi. 40, fig. 31). Lengthened and slender, 

 smoothish, the sculpture sub-obsolete on body-whorl, except at base ; 

 basal keel strongly pinched, as in typical distorta, but no noticeable 

 pit or trench behind outer lip. Fleshy, with narrow, spaced, 

 obliquely descending dark stripes. Aperture less than half the 

 alt. ; outer lip scarcely sinuous ; columellar fold strong, compressed 

 and more horizontal than in the type. Suture conspicuously mar- 

 gined. 



Alt. 41, diam. 15 mill. 



Alt. 38,diam. 14 mill. 



Described from specimens in the R. Swift collection in Mus. A. 

 N. S. P., received by him from Maracaibo, and believed by him to 

 be from Cucuta, Prov. Pamplona, U. S. Columbia. It has the 

 slender contour of var. guairensis, and the pinched basal keel of 

 typical distorta. 



Var. GUAIRENSIS Jousseaume. (pi. 40, fig. 21, Jousseaume's type, 

 and 22, from La Guayra ; fig. 23, from Caracas.) Smaller, more 

 lengthened and more slender than the typical distorta ; base less 

 pinched. Color whitish or fleshy, clouded longitudinally with 

 purplish-brown. Surface strongly sculptured with longitudinal 

 close wrinkle-striae, conspicuous below sutures, more or less broken 

 into long granules on body-whorl, which is less compressed than 

 in distorta and scarcely excavated behind outer lip. 



Aperture generally less than half the alt. of shell, the opening 

 less sinuous, less contracted than in distorta. Outer lip less thick- 

 ened inside and but slightly sinuous ; basal margin less contracted ; 

 parietal fold rather more horizontal, and often with a callus below 

 its outer end. Lip white ; parietal wall generally brownish within. 



Alt. 40, diam. 15 mill. 



Alt. 45, diam. 16 mill.
