correspond with the denticles within, that behind the labrum 

 being remarkably deep. Pa^a mmuscula *, Morelet, closely 

 resembles this species. 



Ennea suhhyalina. (PI. VI. fig. 13.) 



Testa cylindracea, ad apicem obtusa, hyalina, nitida, anguste riraata ; 

 anfraet. 7, leviter convexi, laeves, ad suturam quasi anguste mar- 

 ginati, ultimus antice constrictus, pone et infra labrum scrobicu- 

 latus ; apertura ringens, longit. totius 5 aequans, dentibus albis 

 sex munita ; peristoma album, expansum et reflexum, marginibus 

 callo tenuissimo juuctis. 



Longit. 6 millim., diam. 2| ; apertura 2 longa et lata. 



Hah. Mamboia, at an altitude of 4000 to 5000 feet {Last). 



Five of the teeth within the aperture are about equal in 

 size. Two are on a columellar prominence, two opposite on 

 the outer lip, and the fifth at the lower part of the aperture. 

 The sixth parietal tooth is thin, lamellar, curved, and joins 

 the extremity of the labrum. E. larva, Morelet, is a smaller 

 species, with longer whorls and only a single tooth on the 

 columella. 



Ennea subjlavescens. (PI. VI. fig. 14.) 



Testa cylindracea, supeme obtusa, imperforata, nitida, subpellucida, 

 dilute flaveseens : anfraet. 7, convexiusculi, la^ves, superne quasi 

 anguste marginati, ultimus pone et infra labrum scrobiculatus ; 

 apertura parva, longit. totius | adaequans, valde ringens, dentibus 

 9-10 inaequalibus, albis munita ; labrum leviter expansum et 

 incrassatum. 



Longit. 6 millim., diam. 2 ; apertura 1| longa et lata. 



Hah. Same as E. suhhyalina. 



This species is remarkable for its cylindrical form and the 

 armature of the mouth. The columella is prominent, with 

 three teeth upon it ; two teeth are at the lower part of the 

 aperture, three, of which the middle one is largest, within the 

 right lip, and a very prominent, thin, squarish one on the 

 whorl and joining the termination of the labrum. Three 

 out of four specimens exhibit a tenth minute denticle at the 

 lower part of the mouth. 



Ennea amicta. (PI. VI. fig. 15.) 



Testa anguste perforata, pupiformis, albida, epidermide tenui, pallide 

 viridi-ilavescente induta, subnitida; anfractus 7, convexiusculi, 



• This species is figured (Joum. de Conch. 1877, pi. xii. fig. 5) under 

 the name P. Fischeriana.
