This species differs from E. Hanningtoni in being a little 

 stouter, in having some strong strise behind the labrum, and 

 in the armature of the mouth. Of the five teeth, one of the 

 largest is on the middle of the outer lip, a small one is at the 

 base of the aperture, a similar one on the middle of the colu- 

 mella, a very minute one close to the upper extremity of the 

 outer lip, and the fifth, which is about the same size as that 

 on the labrum, is close to the very small one, thin and lamel- 

 lar. E. quadridentataj Martens, is very like this species. 



Ennea fortidentata. (PL VI. fig. 6.) 



Testa pupiformis, pseudorimata, alba, nitida, ad suturam minute 

 denticulata ; anfract. 8, parum convexi, oblique striatuli, lente 

 crescentes, ultimus pone et infra labrum, etiam in regione umbili- 

 cali valde scrobiculatus ; apertura ringens, dentibus sex insequa- 

 libus munita, lorigit. totius i paulo superans ; perist. late expan- 

 sum, reflexum, album. 



Longit. 9 millim., diam. 4| ; apertura 2^ longa et lata.

The teeth in this species, with the exception of a very 

 minute one on the body-wall just above the columella, are 

 large and strong. Two are on the outer lip, a bifurcate one 

 on the columella, one at the base of the aperture, and the 

 fifth, which is lamelliform, near the junction of the outer lip 

 with the whorl. The deep pit behind the columella produces 

 a somewhat umbilicated appearance. Quite distinct from E. 

 natalensis, to which it is allied. 



Ennea consanguinea. (PI. VI. fig. 7.) 



Testa E. fortidentatce similis, sed paulo minor, fortius striata, aper- 

 tura dentibus quiuque diversis mimita. 

 Longit. 7^ miUim., diam. 4 ; apertura 2| longa, 2 lata.

This species is very like E . fortidentata in form, but differs 

 in being rather more strongly striated and in the armature of 

 the mouth. There are two teeth, of which the upper is the 

 smaller, on the outer lip, a strong bifurcate tooth on the 

 columella, a large lamellar tooth, also bifurcate at the end 

 nearest the columella, joining the upper end of the labrum, 

 and a fifth, somewhat squarish denticle is situated at the lower 

 part of the aperture, but further in than the other teeth.
