1881.] Recent Mollusca during the year 188o. 713 
by the lamented Pourtalés many years ago on the Florida reefs. 
The species referred to in this article are, in part if not wholly, 
members of the deep sea fauna, strictly speaking. A number of 
the species mentioned in the article, are described as of “ Verrill 
and Smith,” in recognition of the labors of Mr. Sanderson Smith 
of the Fish Commission, upon the part of the collection embrac- 
ing the Mollusca. 
In the same journal (1. c., p. 284, April, 1880), Verrill gives a 
“ Synopsis of the Cephalopoda of the north-east coast of Amer- 
ica,” with five plates. This is composed chiefly of notes or addi- 
tions to knowledge in regard to species heretofore described. 
In the Proc. U. S. National Museum (Vol. 11, pp. 356-499), 
Professor Verrill publishes a ‘ Notice of recent additions to the 
marine Invertebrata of the north-eastern coast of America, with 
descriptions of new genera and species, and critical remarks on 
others.” * This consists of two parts, the first (1) relating to the 
mollusks, with notes on annelids, etc., collected by the U. S. Fish 
Commission, and the second (111) comprising a catalogue of Mol- 
lusca recently added to the fauna of Southern New England. 
Although the latter part (pp. 401-409) did not appear until Jan. 
10, 1881, the publication, which has also appeared separately, will 
here be considered as a whole, for the sake of convenience. Part 
of the new species had previously been published in the Am. 
Fournal of Science and Arts for November, as already mentioned. 
In this article one hundred and fifteen species of Mollusca are 
described as recent additions to the fauna of New England, 
which, almost without exception, have been obtained by the par- 
ties employed by the U. S. Fish Commission, directed by Profes- 
sor S, F. Baird, and under the immediate supervision of Professor 
Verrill, who has been aided in the wérk’ by Mr. Sanderson Smith, 
Dr. A. S. Packard, Jr., Messrs. Richard Rathbun, H. E. Webster 
and several other well-known naturalists. Particularly rich 
results have been obtained in depths from sixty-five to five hun- 
dred fathoms, south from Narragansett bay extending to the mar- 
gin of the so-called “ coast shelf” of the continent in this vicinity, 
about ninety miles from the coast. It may be questioned whether 
all the forms obtained can be with entire accuracy denoted as be- 
longing to the “ New England” fauna, since some of them are, 
without doubt, members of the trne deep sea fauna, and may be 
found hereafter to extend widely throughout the Atlantic sea-bed
