The apex of this species is very peculiar, being large, smooth, and 

 somewhat uncoiled.

The brownish markings are irregular in shape and direction, and 

 give most of the specimens the ap]>earance of being mottled with 

 brown and white. Some examples, however, which have only a 

 brownish zone round the middle of the body-whorl, bear consider- 

 able resemblance to Barleeia rubra, Montagu. That species has 

 not the same spiral striation on the upper volutions. 



RissoA EPHAMiLLA. (Plate XXI. fig. 22.) 



Testa ovato-pgramidalis, laevigata, albida, infra suturam opaco- 

 albo et rufo-fusco onaculata ; anfract. 6, vix convexi, ultimus 

 ad basim lineis radiantibus fuscis ornatus ; apertura rotun- 

 data, longit. totius j subcequans; columella fiisco-purpureo

 Longit. 4 millim., diam. 2. 



This species must not be confused with li. cala. It is a little 

 larger, somewhat more solid, has rather less convex whorls, and is 

 not coloured in the same way. Both have the columella stained 

 witli a brown or purplish-brown colour, and united to the outer li]) 

 above by a thin callus.

 interdum piaulo excavati, in medio aut obtuse vel subacute

In some specimens the walls are much more angular than in 

 others, and the longitudinal plicae vary also very much in 

 development.
