FAUXULUS. 243 



chipped as in the co-type, so verifying that part of the orig- 

 inal description recording the peristome as continuous. Of 

 the co-type it would be more accurate to say that the ends of 

 the peristome converge and are connected by a callus. Dimen- 

 sions of co-type, alt. 6.96, lat. 3.38 mm." 



4. FAUXULUS LAYABDI (Benson). PI. 41, figs. 4, 5, 6. 



Shell arcuately rimate, long-conic, obliquely striatulate, 

 whitish [dead] ; spire long-conic, at the apex rather obtuse; 

 suture impressed. Whorls 9, the upper ones somewhat con- 

 vex, at the apex convex, the rest somewhat flat, last whorl 

 ascending in front, narrowed behind the aperture, somewhat 

 scrobiculate, the base compressed-crested. Aperture trian- 

 gularly obovate, vertical, shortly free, six-plicate; peristome 

 expanded throughout, the margins thin, acute, right margin 

 with three plicae, columella with one descending fold. Pari- 

 etal wall with an angular and a second remote one, all deeply 

 entering. Parietal margin having a remote denticle between 

 the inferior parietal fold and the columella. Length 8 mm.

Mr. Benson first described this species from dead and 

 broken shells, subsequently giving additional details (which I 

 have incorporated into his description) from fresh examples. 

 Figs. 4-6 are from Cape Point specimens supplied by Major 

 Connolly. The shell is semitransparent-brown (auburn of 

 Eidgway) when fresh. The trumpet-like mouth and long 

 lamellae, which almost fill the aperture, are its more noticeable 

 characters. 'Fhe lower palatal plica is much larger than the
