254 A, E. Verrill—Mollusca of the New England Coast. 
usually light chestnut-brown, more or less lustrous, somewhat trans- 
lucent, but it is sometimes tinged with greenish or grayish brown, 
in color conforming to the sea-weeds on which it lives. 
Length of the largest specimens, about 3™"; breadth, 2™™; length 
of body-whorl, about 2™™; of aperture, about 1™™. 
Newport, R. I, at high water mark, among decayed sea-weed, 
1880; Huntington, L. L, between tides, (coll. Telkampff); near 
Brooklyn (Lea.) 
This species, when found by me in 1880, was identified with A. 
Grayana, but the specimens obtained at that time were immature. 
An examination of larger and more mature specimens, from Hunting- 
ton, L. L, and a direct comparison with a series of specimens of 
AE Grayana, sent to me by the Rev. A. M. Norman, has convinced 
me that, though closely related, they must be considered distinct 
species, unless A. Grayana be more variable than is indicated by 
European writers. Our species, when with the same number of 
whorls, is less than half the size of A. Grayana, and it has, propor- 
tionally, a much more slender form, with a more acute spire and 
more minute nucleus. The aperture is much smaller and narrower 
and the whole shell is much more delicate in form and texture. The 
color is a clearer chestnut-brown than any of the European specimens 
which I have seen, though this is, perhaps, a character of no great 
importance. In habits and in the situations in which it is found, it 
agrees precisely with the European species, with which it also agrees 
in the structure of the soft parts, as shown by the figure formerly 
published by me. 
Eulima stenostoma Jeffreys. 
Verrill, these Transactions, vol. v, p. 536. 
This species, not previously known on our coast south of the 
Gulf of St. Lawrence, was taken in 1883 by the Albatross at stations 
2043, 2076, 2084, 2096, 2103, in 906 to 1467 fathoms, and at station 
2115 off Cape Hatteras, in 843 fathoms.

Specimens of this species were taken by the Albatross considerably 
exceeding in size those originally described by me. By Jeffreys 
(Proc. Zool. Soc. London for 1883, p. 98) this species has been iden- 
tified as Zrochus Ottoi Philippi,* which he also considers identical 
* Trochus Ottoi Philippi, Moll. Sic., vol. ii, p. 227, pl. 28, fig. 9.
