DESCRIPTION OF A NEW SPECIES OF OLIVA. 

 By F. Gr. Ekidgman. 



Read lOth November, 1905. 

 Oliva Smithi, n.sp. 

 Shell ovately cylindrical, with a short acuminate spire; whitish, 

 with a reticulation of zigzag lines, some being light brown, others 

 very dark rich brown, interrupted here and there by longitudinal 

 greyish-blue streaks, especially towards the labrnm ; whorls 7-8, the 

 3 to 4 apical ones constituting the prutoconch, corneous, and somewhat 

 convex, the rest flatly sloping or even faintly concave, more or less 

 blotched with dark brown above, and divided by a deeply channelled 

 suture ; the last whorl with curved outlines and with the basal 

 fasciole more or less lineated or blotched with brown; aperture 

 somewhat narrow, dark purplish within, but white at the labrum ; 

 columellar side with about fifteen to eighteen transverse plicae or lirae 



upon a defined white callus, which at the anterior end is reflexed over 

 the whorl as in other species of the genus. Length 22, diam. 10 mm. 



Hab. — Unknown. 



Here and there the reticulate markings are interrupted by longi- 

 tudinal greyish streaks as if indicating pei'iods of arrested growth. 

 The above are the dimensions of the largest specimen seen._ Another 

 example equally adult is 18'5 mm. in length and 8-5 mm. wide. 



The two specimens which are now in the British Museum, and 

 which may be considered typical, have been in my possession some 

 months, and were thought by me to be Oliva ' steUeta,'' Duclos, until 

 four more specimens were sent me by Mr. Tomlin, of Chester. I then 

 showed them to Mr. Smith, who after carefully comparing them with 

 the figure and description of 0. stelleta given by Duclos in Chenu's 

 work, came to the conclusion, with which I quite agree, that this 

 shell is not Duclos' 0. stelleta, but a new species. 



As I am indebted to Mr. Smith for first detei'mining and then for 

 very greatly assisting me in describing it, I have given it the most 

 appropriate name of Smithi.
