PART III.— CATALOGUE OF RECENTLY ADDED TO THE FAUNA OF SOUTHERN NE"W ENGLAND. By A. E. VERRILL.

The following lists include 130 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 13 and October 2, on the outer bank or slope, 70 to 115 miles south from Martha's -Vineyard and Newport, K. 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 ISTew England or to the northeastern coast of America are indicated by an asterisk previously' species asterisks ; ; undescribed by two those known previously from our northern coasts have N prefixed ; those from the middle i^arts of the coast have m, and are neither specially southern nor northern ; those oceanic species belonging to the surface fauua 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; I, unusually large; j, young.

DESCRIPTION OF A NEW i^PEt'IES OF NEMICHTHVS (NEMICHTHYS AVOCETTA), FieOlTl PUGET SOUND.

By I>AVID S. JORDA]\ and CHARLES H. 01I.BERT.

Nemichthys avocetta, sj). 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, sharj), 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 liere 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, 1870.
