46 STROPHOCHEILUS-THAUMASTUS. 



Very nearly allied to S. melanocheilus, but in this species the 

 spiral series of beads seem much more strongly developed. 



Group of S. taunaisii. 



Im perforate ; the nepionic shell sculptured with fine vertical more 

 or less waved riblets or striae. 



S. FOVEOLATUS Reeve. PI. 24, figs. 71, 72, 73. 



Shell hardly perforate, oblong-ovate, rather solid, somewhat shin- 

 ing, longitudinally striatulate or obsoletely plicatulate, transversely 

 sculptured with inconspicuous close impressed-punctate lines. Chest- 

 nut-brown, with a narrow whitish band below the suture ; covered 

 with a very thin corneous epidermis, sometimes having transverse 

 irregular and flexuous whitish lines (fig. 73). Spire conoid, exserted, 

 the apex somewhat obtuse ; suture plicate, slightly crenulate, and 

 around the last whorl it is white. Whorls 6, slightly convex, the 

 earlier foveolate below the sutures, under a lens seen to be minutely 

 costulate-striate. Last whorl obliquely descending. Columella 

 suboblique. 



Aperture ovate-acuminate, violaceous inside, somewhat pearly, 

 fourth-ninths to one-half the shell's length ; peristome slightly re- 

 flexed, somewhat thickened, white ; its ends joined by a very thin 

 callus ; right margin regularly arcuate ; columellar margin dilated 

 and reflexed above, nearly closing the perforation. 



Alt. 68, diam. 33 mill. (Hidalgo).
