Chesapeake Bay. in 56 to 300 fathoms: at station 898. in 300 fathoms. 
165 specimens were taken, 115 of them living- Off Delaware Bay. 
in 156 m l 435 fathoms, in 1881. 
This shell is closely allied to S. propinquus (Alder) of Europe, to 
which I formerly referred it, with doubt. It agrees very well with 
that species in form and sculpture ; in the canaliculate suture ; and in 
the character of the epidermis, except that our shell -eems to he con- 
stantly and more decidedly hairy. Our species is, however, a larger 
and more robust shell, and its nuclear whorls are totally different, for 
according to Jeffrey’s description and figure, >. proq ■> always 
has a regularly spiral nucleus, with ti e first whorl minute and not 
turned up ; this is, also, the case with an authentic specimen, in my 
possession, received from the Rev. A. M. Xorman. 
>. tur-jU b.ts Jeff. Friele is also closely related to our si eeies, in 
form, sculpture, epidermis, and in having a similar nucleus i as figured 
by Frieleh but it has a shorter canal, and the f- »rm of the operculum 
and character of the dentition are very different.

I refer to this species, with some doubt, a small species of Sipho t 
of which I have only two j _ - eeunc s, take - 
off the coast of Maine, by Dr. A. S. Packard and party, on the 
rt Bache,~ while dredging there for the U. S. Fish Com., in 1873. 
This shell is evidently distinct from all the other species found on 
our coast, but the absence of the operculum and soft parts, as well as 
the immature -late of the shell, makes the identification somewhat 
uncertain, but it agrees well with Gray’s original description, so far 
as that goes.* It also corresponds nearly with the figures given by 
Leche. except that it is younger than the shell figured by him. 
The whorls are well-rounded; suture somewhat impressed; numer- 
ous (about 12 on the fourth whorl), fine, raised cinguli cover all the 
surface; the- e are n-paratcil only by narrow inc-i-o 1 lin s<m the early 
whorls, but on the fifth the intervals are wider than the cinguli ; the
