Eulimella (or Menestho) lissa Verrill, sp. nov. 
PLATE XXXII, FIGURE 6. 
Shell small, white, polished and somewhat lustrous, slender, some- 
what obelisk-shaped, composed of about eight flattened whorls, 
without any sculpture. Apical whorl very small, abruptly up- 
turned, its diameter only about half that of the next whorl. 
The succeeding whorls increase rapidly at first, but the later ones 
less rapidly, so that the shell has a somewhat Pupa-like form. The 
whorls are only slightly convex in the middle, but the suture is dis- 
tinctly impressed. The aperture is irregular ovate, acutely angled 
posteriorly, broadly rounded anteriorly, with the inner margin sinuous 
and pretty strongly emarginate at the base of the columella. The 
outer lip is thin and sharp, only moderately convex in the middle, and 
projecting only slightly or not at all, there being no distinct sutural 
notch; anterior margin evenly rounded, only very slightly effuse, 
sometimes slightly flaring, at other times not at all so; columella- 
margin regularly excurved, passing into the anterior margin with- 
out forming an angle, its outer edge usually everted ; the inner lip, 
at the junction of the columella-margin with the body-whorl, some- 
times has a perceptible emargination, but in other examples a 
strongly excurved outline. The base of the shell is only moderately 
produced, without any sculpture, nor any trace of an umbilicus. 
Length, 6™ ; breadth, 1-8"; length of body-whorl, 2:8"; length 
of aperture, .1-2™™. 
Station 2109, off Cape Hatteras, in 142 fathoms (No. 35,433), nu- 
merous specimens, living and dead. Steamer Albatross, 1883. 
This species has the general appearance of certain species of Odos- 
tomia, but there is no trace of a tooth on the inner margin. It is 
remarkable for the small size of the apical, as compared with the 
succeeding whorls, and also for its pupiform or obelisk-shaped out- 
line. In these characters it differs from the species of Arlimella 
herein described, and from those previously discovered on our coast. 
The aperture, also, is smaller than in most of the related species, and 
the outer lip projects less distinctly forward. It resembles in form 
species of Menestho, but has no spiral grooves. It seems to have 
been very abundant at the locality where these specimens were 
taken.
