been broken off squarely. Length, 12™; diameter of larger end, 2.5°"; 
of small end, .5™". 
Another specimen of similar character, 10°" long and 2.5"" broad, was 
dredged in the Gulf of Maine, 107 fathoms (station 9 B), 1873. With 
the last-named specimen there was, however, a perfect living specimen, 
7" long and 2"" broad, having the posterior end perfect and provided 
with the characteristic digitations around the opening.

42, figs. 20 a-b. 
A specimen smaller and more slender than the preceding species, 
and which I refer to S. affinis, was dredged by us, in 1877, in Bedford 
Basin, near Halifax, Nova Scotia, 35 fathoms, soft mud. It is 6" in 
length, 1™" in breadth, slightly curved, round, smooth, glossy, and trans- 
lucent. The posterior opening is small and appears to be perfect; it 
shows only a faint indication of a notch on the convex side. 
Siphonentalis Lofotensis (M. Sars). 
G. O. Sars, Moll. Reg. Arct. Norv., p. 104, pl. 20, figs. 11 a, b; pl. i, fig. 3. 
A few specimens that agree well with the figures and description of 
this species were taken at station 891, in 500 fathoms. 
It is longer and more tapered than the last, and much less translucent. 
Cadulus propinquus G. O. Sars. 
Moll. Reg. Arct. Norv., p. 106, pl. 20, figs. 15 a,b; pl. i, fig. 5 (dentition). 
This shell occurred in considerable numbers, living, at station 871, in 
115 fathoms. It is a small, polished species, rather stouter and more 
swollen than the next. 
Cadulus Jeffreysii Monterosato. 
Cadulus subfusiformis? Jeffreys, British Conch., v, p. 196, pl. 101, fig. 3 (non 
Sars, teste Monter.). 
Several specimens of a small Cadulus, somewhat swollen in the middle 
and rather strongly bent, I refer to the above species. The posterior 
aperture is simple in most of them, but slightly notched in others. 
Station 871. 
Cadulus Pandionis Verrill & Smith. 
Amer. Journ. Sci., xx, p. 397, Nov., 1880. 
A very much larger, highly polished species occurred at many of the 
stations, but most abundantly at 569 to 871 and 873 to 877, in 85 to 192 
fathoms. It is swollen on the convex side, in the middle, and slightly 
angulated or gibbous at about the anterior third. It is transversely 
elliptical in section; the anterior end decreases to the aperture, which 
is oblique, the lip being prolonged on the concave side. Posterior aper- 
ture small, with a semicircular notch above and below. Length, 10""; 
breadth, 2.25"; of mouth, 1.75""; of posterior aperture, 40",
