EULIMELLA. 315 



dinal increase, rather short than otherwise, and plano- 

 convex. The suture, though simple, is very distinct, and 

 a little slanting ; above it the surface is usually more con- 

 vex, below it generally more planulate. The basal de- 

 clination is rounded and gradual. The axis of the shell is 

 distinctly jjerforated. The aperture, which is devoid of 

 sculpture, occupies one-third of the entire length ; it is of 

 a subpyriform oval shape, being rounded, though not 

 broadly so below, and rather abruptly contracted above. 

 The acute and simple outer lip neither expands nor pro- 

 jects, it is decidedly straight at first, but becomes a little 

 curved anteriorly where it joins the columella without 

 angulation. The pillar lip is straight and thin above, a 

 little reflected and curved below ; it forms a very obtuse 

 angle with the convex and moderately slanting base of 

 the preceding turn. None of our specimens are more 

 than the tenth of an inch long, and scarcely measure half a 

 line across ; we suspect, however, that these will by no means 

 prove the limits of its growth when the species becomes 

 better known. 



At present the very few examples that have been 

 taken were dredged within a few yards of the shore (at 

 low water) near Brixham in Torbay, by Dr. Batters- 

 by and Mr. Hanley, from a bottom at some six or seven 

 fathoms depth. Although taken alive, the animals were 

 unfortunately dried up before the shells were observed and 

 selected from the mass of dredged matter ; hence we can 

 at present give no account of the mollusk from our own 

 observation. Professor Loven, however, has described and 

 figured the animal of his clavula as having broad short ten- 

 tacula which are united at their bases, somewhat swollen 

 out at their lower parts, and having the eyes rather dis- 

 tantly placed near their inner bases. The mentum is
