seems like a continuation of the suture. The sculpture is 

 finer on the last whorl than at the summit. 



6. P. ABETIFIANA Rolle. PI. 61, figs. 8, 9. 



Shell imperforate, long-ovate, rather thin, subdiaphanous, 

 glossy, corneous-brown, costellate, the riblets equal, straight, 

 evanescent towards the suture and periphery of the last 

 whorl. Spire turrited, the apex obtuse. Whorls 7 to 8, a 

 little convex, separated by an impressed, crenulate suture, 

 slowly increasing, the last carcely as long as the spins 

 rounded at the base, smooth below the middle, somewhat 

 sculptured with fine striae. Aperture slightly oblique, irre- 

 gularly ovato, acuminate above, truncate below. Columella 

 somewhat twisted, broadly truncate at the base; outer lip thin 

 and fragile. Length 23, diam. 9.5 to 10 mm., alt. of aper- 

 ture 9 mm. (Rolle) .

Nearly related to parturitus, but distinguished by the in- 

 terruption of the sculpture at the periphery (Kobelt). Api- 

 cal sculpture not described. From Kobelt 's course in plac- 

 ing th species in Homorus, it seems likely that the apex has 

 not the characteristic Pscudoglessula sculpture. 



7. I*. IMM<:A Put/oyH. PI. 03, fig. 31. 



Shell imperforate, ovate- turrited, rather solid, closely pli- 

 catulate-striate; brown or brownish. Spire conic, obtuse. 

 Whorls 7, convex, regularly increasing, the first densely 

 cofltulatc, the last oblong, glossy, silicate, very delicately sub- 

 angulatc at the periphery and marked below with a spiral 

 impressed line. Aperture oval, the lip acute, slightly ex- 

 panded, bluish white inside. Columella brown, a little 

 Straightened, arching forward, where it is narrowly taper- 

 ing-truncate and folded. Margins joined by a very thin cal- 

 Imis. Length 37, diam. 17, length of aperture 18 mm. 

 (Putzcys).
