an olive-colored, ciliated epidermis; the canal is shorter and more 
curved and twisted; the suture is slightly channeled, and the aperture 
is broader than in either of these species. The sculpture consists of 
regular, narrow, spiral grooves. The aperture is white.

This species was dredged in the summer of 1879, by the “Speedwell”, 
off Cape Cod, in 90 fathoms. It was dredged by us in 1877, off Cape 
Sable, Nova Scotia, in 80 to 90 fathoms, compact sand, and off Halifax, 
in 100 fathoms, and has often been browght in from the banks off Nova 
Scotia by the Gloucester fishermen, but it was not previously actually 
known from the New England coast. 
Nassa nigrolabra Verrill, sp. nov. 
Shell minute, long-ovate, nearly smooth, pale olive, with the edges of 
the lips blackish. Whorls five, slightly rounded, with shallow sutures ; 
Spire elevated, not very acute. Surface covered with close, regular, 
microscopic lines of growth, and with less distinct revolving lines; canal 
with a few minute, distinct, spiral grooves. Aperture short-ovate; canal 
wide and very short; outer lip rounded, with edge flaring, thickened 
and revolute, with a row of minute nodules on the inside; inner lip con- 
sisting of a bread, smooth, glossy, brownish-black deposit of enamel on 
the body-whorl and columella; columella nearly straight ; no umbilicus. 
Length, 2.85""; breadth, 1.40"; length of aperture, 1.207". 
Station 870, in 155 fathoms; one specimen. It is referred to Nassa- 
only provisionally. » the animal is not known.

In addition to the localities off Cape Cod and on Le Have Bank, pre- 
viously cited by me, this species has been taken at other localities on 
our coast. It was taken by Prof. 8S. I. Smith and myself at Eastport, 
in 1864; by Prof. H. E. Webster at Seal Cove, Grand Menan, in 1872; 
by Mr. J. F. Whiteaves in the Gulf of Saint Lawrence; and by our party 
in 1880, twenty miles south of Block Island, in 28 fathoms. 
Lunatia tevicula Verrill, sp. nov. 
Shell light, thin, and rather delicate, broad-ovate; spire moderately 
elevated, subacute. Whorls five, evenly rounded; suture distinct. 
Aperture ovate, well rounded below. Outer lip short, sinuous along 
the edge, the upper portion considerably advancing where it joins the 
body-whorl. Inner lip partially reflexed over a rather small, deep 
umbilicus, but not thickened, and forming a mere film on the body-whorl, 
above the umbilicus. Surface covered with distinct and rather coarse, 
sinuous lines of growth, parallel with the edge of the lip, and, like it, 
advancing as they approach the suture. Color (of a dead but fresh
