MARINE MOLLUSCA OF MADEIllA. 257 



nizable under the microscope, but tlie surface is not very glossy. 

 Colour a rich deep chestnut, with a pale yellowish narrow band 

 round the base of each whorl and occupying the outer lip and 

 estreme base of the shell. Spire narrow, with straight outlines, 

 the whorls being barely rounded. Apex small, but very bluntly 

 rounded, and its two sides are scarcely unequal. Whorls 6; of 

 regular and slow increase, barely rounded. Suture slightly 

 oblique and a little impressed. Mouth rather short and somewhat 

 broad. Outer lip has the edge slightly sinused near the body 

 and convex to the base — in direction it runs straight; on the 

 broadish base it is fairly patulous and in its curve regular. 

 Inner lip a longish but very little convex curve across the body 

 to the point of the short pillar ; it is a little thickened, but not 

 in the least expanded.— H. 0-067. B. 0-027. 



In deep water at the east end of the island — not rare. 



This species is very like JE. Jeffrey sia7ia, Brus., but is smaller 

 and narrower, with fewer, less rounded whorls, a much blunter 

 spire, a shorter base, and a much shorter and rounder mouth ; 

 its colour also is a much deeper richer chestnut. 



It is absent in all the other collections I have seen. 



25. EULIMA SOEDIDA, n. sp. 



Shell shining, very small, straight, with a very narrow spire, 

 very blunt tip, barely convex whorls, very blunt base, and oval 

 mouth. Sculpture very doubtful, if any. Colour a sordid 

 yellow. Spire narrow and straight. Apex very small, but blunt 

 and round ; its two sides are very equal. Whorls 7, of very 

 regular and slow increase, almost perfectly flat on the sides. 

 Suture scarcely impressed, but visible from the transparency of 

 the shell — hardly oblique. Mouth very small, oval, but narrow 

 pointed at the top. Outer lip : its edge advances a little from 

 where it leaves the body, but the whole curve of the mouth is 

 very regular. Inner lip is very slightly patulous on the pillar 

 with a minute chink behind it, and it is very feebly angulated 

 where it joins the body.— H. 0066. B. 0*024. 



Punta de Sao Lourengo — rare. Found only by myself. 



This species is very much less like IS. Jeffreysiana, Brus., than is 

 E.fulva. From the latter it differs in being smaller with nearly 

 a whole whorl more, it is narrower, the mouth is smaller and 

 rounder, the base more truncate, the whorls are less rounded, 

 the suture less impressed, the apex is smaller and rounder, and
