140 A, EF. Verrill— Mollusca of the New England Coast. 
The original assorting and preservation of the deep-sea specimens 
taken by the Albatross was largely done by Mr. Sanderson Smith, 
who went on all the cruises of the Albatross, except a few of the 
earliest. He was assisted by several other members of the party, 
and especially by Ensign W. E. Safford, U.S. N. 
My work has also been particularly facilitated by the care and 
skill with which the final assorting, cataloguing, and labeling of the 
large collections have been done by my assistant, Miss K. J. Bush, who 
has, also, made many identifications of the described species, and 
given aid in other ways. 
When the various lots were first examined and assorted, at Wood’s 
Holl, last summer, during the dredging season, many of the new 
species, especially the largest and most striking 
5) 
forms not before observed on our coast, both by Mr. Sanderson Smith, 
were recognized as 
who had special charge of the shells, and myself. For such species, 
in this article, “ Verrill and Smith” are usually given as authorities, 
but the writer is alone responsible for the descriptions of all the 
species, as in his previous papers on the same subject. 
Some of the previously known species, first discovered on our 
coast last summer, were first identified by Mr. Smith, and others by 
Miss Bush, but the writer has independently examined and confirmed 
all such species, given in this paper. 
CEPHALOPODA. 
Leptoteuthis Verrill, gen. nov. 
Body elongated and slender, pointed behind, with a well developed 
terminal fin. Head relatively large, much elongated. Eyes not ex- 
sert, with simple thin lids. Mantle free dorsally, with a special dor- 
sal and two lateral connective cartilayes; the lateral ones simple, 
tubercle-like, corresponding to a roundish cartilage-pit on each side 
of the siphon. Arms slender, the ventral ones much the largest and 
longest. Suckers depressed, in two rows. Tentacular arms rather 
long, slender, with a somewhat expanded terminal club, bearing sim- 
ple suckers, and with a row of small sessile suckers and rounded warts 
along the whole length of the inner surface of the slender portion. 
Gills and viscera anteriorly situated. Stomach short, with a saccular 
appendage. 
This genus has, hitherto, not been distinguished from Leachia and 
Loligopsis. From the typical forms of these groups it differs greatly 
in anatomical characters, as well as in external appearance. From
