MAEINE MOLLUSCA OP MADEIRA. 259 



with a very small tip, an attenuated base, and a small narrow 

 oval mouth. Sculpture none, the surface being glassy. Colour 

 hyaline white. Spire exceedingly high and narrow ; the contour- 

 line on the right is quite straight, that on the left slightly curved, 

 but both are perfectly uninterrupted by any swell of the whorls 

 or contraction of the suture. Apex minute and symmetrically 

 rounded. Whorls 11, of very slow and regular increase, the 

 last is both short and narrow but not contracted. Mouth 

 small, narrow, oval, pointed above. Outer lip thin, straight, its 

 edge hardly retreats above or advances at the periphery. Inner 

 lip has a slightly thickened edge and curves very regularly 

 across the body and down the pillar, with hardly the slightest 

 furrow behind it ; it has no truncation at the base. — H. 0-11. 

 B. 003. 



One specimen I got from deep water in Funchal Bay. 



This is a very much slimmer form with a finer apex and 

 narrower spire than any of the other Madeiran species, none of 

 which in their youngest state approach it in these respects ; even 

 the small form of E. Philippii, Weiuk., of the same length is 

 much broader, has fewer wliorls, a much larger base, rounder 

 mouth, and more projecting outer lip. U. psila, Wats., from the 

 "W. Indies, resembles it most, but is a larger shell with a coarser 

 apex. 



28. EULIMA TEFNCA, n. sp. 



Shell conic-oblong, ivory-white, strong, straight in all its lines, 

 with a broad short base and sharp tip. Sculpture none, the 

 whole surface being brilliantly glossy ; but a feeble flattened 

 varix appears on each whorl and runs interruptedly up the 

 spire. Colour ivory-white, but very slightly pellucid. Spire 

 high and conical, with very straight contour-lines, the whorls 

 being just barely rounded in outline. Apex very small and 

 sharp, but very slightly impressed. Whorls 9, of very slow and 

 regular increase, the upper ones just barely, the lower not at all 

 rounded in outline, the last is short with a truncated well- 

 rounded base. Suture hardly oblique, slightly abruptly but 

 distinctly impressed. Mouth fairly oval, but with its curve on 

 the left-hand side a little constricted, shortly pointed above. 

 Outer lip thick, with a rounded edge which has a feeble and 

 wide sinus above and a slight forward curve about the periphery 

 of the shell. Inner lip a good deal thickened and well defined
