3. Descriptions of fourteen new Species of Land and Marine 

 Shells. By Henry Adams, F.L.S. 



[Received November 27, 1871.] 



(Plate III.) 



Leptoconus (Phasmocontjs) dtj saveli, sp. nov. (Plate III. 

 fig. 17.) 



L. testa convexo-conica, polita, solidiuscula, antice distanter puncto- 

 lirala, roseo-lutea, fasciis tribus ex striis longitudinalibus et ma- 

 culis rufis formatis ornata, seriebus numerosis macularum candi- 

 darum purpureo-lividarum alternantium cincta ; spira acuminata, 

 conica, apice mucronato ; sutura distincta, sursum subcanaliculata, 

 longitudinaliter rufo-striata ; anfr. 10|, superne angulatis, ad 

 apicem nodulosis, anfractu ultimo paulum ventricoso ; apertura 

 mediocri, antice subdilatata ; labro acuto, postice sinuato. 

 Long. 50, lat. 20 mill. 

 Hab. Mauritius {coll. Du Savel). 



This beautiful species, at present unique, is stated to have been 

 obtained from the stomach of a fish, but is in a good state of pre- 

 servation. It appears to belong to the group Phasmoconus, Morch, 

 as regards the surface, texture, and style of painting, but has, never- 

 theless, somewhat the aspect of the genus Nubecula. 



Stylodonta (Erepta) bewsheri, sp. nov. (Plate III. fig. 18) 



S. testa imper/orata, depresso-conica, solidula, plicis acutis, obliquis, 

 undulatis munita, pallide rufo-fulva ; spira breviter elevata, apice 

 obtuso, sutura marginata, valde impressa ; anfr. 6, convexis, lente 

 accrescentibus, ultimo non descendente, ad peripheriam acute ca- 

 rinato, carina compressa, serrata, subtus convexo, medio excavato ; 

 apertura obliqua, angulato-lunari ; perist. simplici, marginibus 

 remotis, dextro sinuato, obtuso, basali arcuato, calloso. 

 Diam. maj. 14, min. 13, alt. 18 mill. 



Hab. Basin du Diable, near St. Denis, Isle of Bourbon (coll. 

 Caldwell) . 



I have named this species after Mr. E. C. Bewsher of Port Louis, 

 Mauritius, who discovered it in the locality above mentioned, which 

 is elevated 1000 feet above the level of the sea. It is closely allied 

 to S. semicerina, Morel., but differs in being imperforate, in the pli- 

 cation of the surface being stronger and more acute (thus causing 

 the keel, which is very compressed, to be serrated), by the whorls 

 being more convex, and by its uniform light reddish-brown colour.
