PART III.—CATALOGUE OF MOLLUSCA RECENTLY ADDED TO THE 
FAUNA OF SOUTHERN NEW ENGLAND. 


By A. E. VERRILL. 


The following lists include 130 species of Mollusca that have recently 
been added to the fauna of Southern New England, mainly through the 
researches of the dredging party of the United States Fish Commission 
on the steamer ‘‘ Fish Hawk”. The greater portion of these, with several 
others undetermined or not yet described, were taken on September 4 
and 15 and October 2, on the outer bank or slope, 70 to 115 miles south 
from Martha’s Vineyard and Newport, R. I., in 65 to 500 fathoms. For 
a list of these localities see p. —. 

In these lists those species which were unrecorded from or entirely 
new to New England or to the northeastern coast of America are indicated 
by an asterisk; previously undescribed species by two asterisks; those 
known previously from our northern coasts have N prefixed; those from 
the middle parts of the coast have M, and are neither specially southern 
nor northern; those oceanic species belonging to the surface fauna have 
O prefixed; southern forms are designated by s; those that are also 
known from Europe are designated by E; those peculiar to America 
by A. ; 

In the tables, living specimens are indicated by an asterisk; dead ones 
by a dagger; m signifies many; sv, several; r, rare; /, unusually large; 
Jj, young.

DESCRIPTION OF A NEW SPECIES OF NEMICHTHYS (NEMICHTHYS 
AVOCETTA), FROM PUGET SOUND. 


By DAVID Ss. JORDAN and CHARLES H. GILBERT. 


Nemichthys avocetta, sp. nov. 

Color translucent white, the lower half of the body covered with 
small, round, black spots, sharply defined; among these some smaller — 
spots. Belly near the median line black. Upper half of body plain, 
colorless. Pectorals and dorsal plain. Anal speckled. 

Body band-shaped, but not strongly compressed; deepest in the 
middle, tapering behind to the long and very slender filament-like tail, 
and anteriorly to a very long and slender neck, which contracts imme- 
diately behind the head. Skin smooth. No lateral line. 

Head proper small, short and rather broad; concave between the 
eyes, with two median ridges; full and broad behind the eyes, with 
three longitudinal ridges. Lower part of head narrow, sharp, so that 
the head would be triangular in a vertical section. Eye very large, 
vertically placed, its length one-third that of the head without snout. 
Nostrils each simple (two on each side), rather large, close in front of 
eye, without tube or flap. Maxillary extending to close behind the eye, 
the mandible somewhat farther. Jaws prolonged, becoming very slen- 
der, long, acuminate, needle-like at tip, somewhat recurved. Upper jaw 
the longer, and nearly four times the length of the rest of the head, 
being 7-8 times its greatest depth. Both jaws with small, very numer- 


* Some of the species here included were discovered in 1875 and 1876, and have been 
recorded in the American Journal of Science. Those with an asterisk prefixed were 
first discovered on our coast this season, or else have not been previously recorded. 
For additional species, not included in my Report on Invertebrates of Vineyard Sound, 
&c., 1873, see American Journal of Science, x, pp. 40, 41, July, 1876.

ous, retrorse, close-set, sharp teeth. Jaws bony, their lateral surfaces 
with retrorse roughnesses. Head naked, covered with skin. 

Gill-openings rather large, oblique, running downward and forward, 
separated by a rather narrow isthmus. Pectorals well developed, half 
longer than eye. No ventrals. Vent under middle of the length of the 
pectorals (when depressed); the anal fin beginning close behind it and 
extending to the tail; its rays soft and rather slender; the membrane 
delicate; its height greatest near the middle and anteriorly, where it is 
somewhat less than height of body, becoming obsolete on the long cau- 
dal filament. Dorsal similar to anal, but lower, beginning close behind 
the oeeiput and running to the tail.

The specimen which is the type of the present description was taken 
in May, 1880, in the harbor of Port Gamble, and was placed by its cap- 
tor in the museum of the University of Washington Territory, at Seattle. 
The president of the university, Prof. A. J. Anderson, presented it to 
the United States National Museum. Its movements in the water are 
said to be extremely active. 

Fishes of this type offer comparatively few specific characters, and we 
are able to separate this species from Nemichthys scolopaceus Rich. of the 
Atlantic by differences in proportion only. According to the detailed 
description and figure of the latter species given by Lowe and Brandt 
(Leptorhynchus or Belonopsis leuchtenbergi, Mém. Acad. St. Pétersb. Sav. 
Etrang., 1854, vii, 171-174), Nemichthys avocetta is distinguished by the 
much slenderer ‘head, longer beak, and higher anal fin, the greatest 
height of the latter being nearly equal to the length of the pectoral 
and more than the depth of the head. So far as known to us, this is 
the first species of the genus thus far taken in the Pacific. A recent 
newspaper account of the capture of a sea-serpent at Victoria, British 
Columbia, perhaps refers to a second example of the same species. 

SEATTLE, WASH., June 10, 1880.
