Shells from South America. oOD 



Aperture : alt. 13, diam. 14 mm. 



Jriab. Argentina. 



The only species which in general outline approaches the 

 present form is E. macasi, Higg., from Ecuador ; this, how- 

 ever, is easily distinguished by its much larger size from 

 that now described. 



Bulimus [Eurytus] dissimulanSy sp. n. (Fig. 5.) 



Shell imperforate, ovate, thin, brown, painted with very 

 closely set, greyish-yellow, wavy, transverse lines, and in- 

 distinct, brownish, spiral bands; whorls 3^, rapidly increasing 

 in size, rather flat, smooth; sutures impressed; columella 

 arched ; peristome slightly thickened, rose-cok)ured;. aperture 

 ovate, somewhat laterally contracted. 



Alt. 30, diam. raaj.. 15 mm.. 



Aperture: alt. 18, diam. 11 mm. 



Hah. Merida, Venezuela. 



The extraordinary painting of this species at first gives 

 the impression that the shell is closely,, vertically, striate ; 

 this, however, is not the case, the appearance being caused 

 by the closely set, greyish-yellow, transverse colour-lines. 



Bulimus [Thaumastus) insolitus, sp. n. (Fig. 9.) 



Shell imperforate, obtusely fusiform, solid, ground-colour 

 dark blackish brown ; extreme apex sunken ; whorls 5^, 

 flattened, the earlier whorls sculptured with very fine, wavy, 

 transverse striae, presenting an almost finely granular appear- 

 ance, the later whorls very coarsely sculptured with transverse 

 ridges crossed by fine, spiral grooves, giving to this portion 

 of the shell a finely beaded appearance, the rows of beaded 

 tubercles being of a yellowish-brown colour, last whorl 

 descending rather rapidly, from the point where the last 

 whorl begins to descend there occurs a supersutural band 

 about three millimetres broad, continued as a peripheral band, 

 and increasing to six millimetres in breadth on the last whorl, 

 on this band the beaded sculpture is less marked and the 

 surface of the shell is of a correspondingly more uniform 

 blackish-brown colour ; sutures impressed, crenulate, whitish, 

 especially towards the latter half of the last whorl ; columella 

 thick, slightly excavated ; peristome lightly, varicosely 

 thickened, brownish yellow, somewhat reflexed below, the 

 margins joined by a thick, polished, brown callus ; aperture 

 ovate. 



Alt. 70, diam. maj. 29*5 mm.
