Eulimella (or Menestho) lissa Verriii, sp. nov. 

 Plate XXXII, figure 6. 



Shell small, white, polished and somewhat lustrous, slender, some- 

 what obelisk-shaped, composed of about eight flattened wliorls, 

 witliout any sculpture. Apical whorl very small, abruptly u})- 

 turned, its diameter only about half that of the next whorl. 



The succeeding whorls increase ra})idly at first, but the later ones 

 loss 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 shar]», only moderately convex in the middle, and 

 projecting only slightly or not at all, there being no distinct sutnral 

 notch ; anterior margin evenly rounded, only very slightly etfuse, 

 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, ofi' 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- 

 toviia, 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 oi Eulimella 

 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.
