Srconp CaTAaLoGuE oF MOLLUSCA RECENTLY ADDED TO THE 
Fauna oF THE NEw ENGLAND COAST AND THE ADJACENT PARTS 
OF THE ATLANTIC, CONSISTING MOSTLY OF DrEP-SEA SPECIES, WITH 
NOTES ON OTHERS PREVIOUSLY RECORDED. By A. KE. VERRILL.

Tue following paper was originally intended to form merely a brief 
supplement to the Catalogue published by me, in 1882, in Vol. V. of 
these transactions, to include such corrections and additions as had 
been noticed up to date. But the discovery of a very large number 
of interesting additional species, many of them new, during the deep- 
sea dredging cruises of the Fish Commission Steamer, Albatross, in 
1883, made it desirable to extend the paper so as to include many of 
the more important of these discoveries. This has caused delay in 
the printing of the paper and much increased its length, and, as I 
hope, its value. Many of the additions made in 1883 are from much 
deeper water than we had previously explored (1,000 to 2,900 fath- 
oms), and consequently from a greater distance at sea; so that these 
cannot-properly be regarded as pertaining particularly to the “ New 
England fauna.” They belong rather to the general deep-sea fauna 
of the western Atlantic. Others are from the deep waters of the con- 
tinental slope, beneath the Gulf Stream, in 100 to 600 fathoms. As 
these deep-sea forms are likely to extend all along our coast, at simi- 
lar depths, and even to foreign waters, I have not thought it desir- 
able to exclude from this paper any deep water species because of 
its having been taken even as far south as off Cape Hatteras, which was 
nearly the southern limit of the dredgings of the Albatross in 1883. 
But I have excluded the strictly southern shallow water forms, dredged 
at moderate depths off the coasts of North Carolina and Virginia, 
though many of them are new additions to the fauna of our coast. 
There are, doubtless, to be added to our list many species of small 
and difficult shells, belonging to certain groups that have not yet been 
fully examined, or of which we have taken only imperfect examples. 
These will chiefly belong to the Budlide, Turbonilla, Odostomia, 
Cryptodon, and Yoldia. 
I am greatly indebted to the skill of Mr. J. H. Emerton for the 
unusually accurate illustrations, and to the U. 8. Fish Commission for 
the privilege of using them in this place.
