Meuavawr Dock, off the Scillies, in 38 fathoms. This is nearest a 

 dwarf form of jE. interiiiedia, from which it differs in being much more 

 solid, the base more produced, the periphery obtusely angulated, the 

 mouth smaller, the whorls convex instead of compressed, the suture 

 more deeply defined, and the whole shell forming a slight curve. My 

 largest are i'5 lines by 075, and the smallest i line by 0*5. I have 

 dwarfs of E. intermedia equally small, from the same district and 

 elsewhere, but they differ in all the above characters. 



I have received this from foreign correspondents as E. brevis Req., 

 and under the same name I have also receivjed, from the same sources, 

 dAvarfs of E. polita and E. interinedia. There is considerable doubt 

 as to the identity of E. brevis^ and as to whether it is a valid species ; 

 but all I can say, from the specimens before me, is that E. petitiana 

 Brus. is identical with the Scillonian shell, and that it bears the 

 same relation to E. intermedia as E. brevis does to E. polita. 



E. anceps Marshall n.sp. — -Shell cylindro-conical, solid, trans- 

 parent, and glossy ; sculpture none ; colour glassy-white (a dead 

 specimen is ivory-white) ; spire long and tapering ; the upper half has 

 a slight curve and is nearly cylindrical, while the lower half more 

 rapidly increases, thus making the profile lines slightly concave in the 

 centre ; the first whorl is semi-globular and blunt, like E. stenostoma, 

 the second and third are convex, the following ones compressed, and 

 the last is comparatively large, convex, and obtusely keeled round the 

 periphery ; suture very slight and oblique, but well defined by the 

 septum of the preceding whorls ; mouth pear-shaped, small (about 

 one-third the length of the shell) ; outer lip thickened, deeply sinu- 

 ated where joined to the pillar, convex and projecting in the centre, 

 and expanded at the base ; inner lip also thickened, especially below 

 the pillar, to which it is attached with very little callosity. L. o"2 in., 

 b. 0-05. 



Off Ar ran, in 31 fathoms, with ^. ephamilla ; three specimens. I 

 have also two examples from the Adventure Bank, dredged by the 

 "Porcupine," and I detected another among some specimens of^. 

 intermedia received from the Marquis di Monterosato, who writes me 

 that he has dredged the same species at Palermo. 



This differs from other British species in the broad blunted apex ; 

 if found without the top whorls, it would probably be assigned 

 to E. intermedia, from which it further differs in the attenuated spire; 

 it is nearest in outline to the var. rubrotincta, but E. anceps has the 

 last whorl larger and convex, with the mouth projecting. It has some 

 resemblance to E. solida Jefifr., but that species is more cylindrical 

 throughout, has a still larger bulbous apex, and an angular base. It 

 also has some of the features of ^. acerrima Wats., but the latter has 

 more whorls (12), a pointed apex, and a different mouth. An unde-
