224 BULLETIN OF THE 
Mr. Dall’s statement, that, judging from the figure, one would not anticipate 
the two species being identical, leads me to think that there may possibly have 
been some confusion in the labelling of the specimens, or there may be two 
species under the same name. 
Dentalium occidentale, var. sulcatum Verrill (Trans. Conn. Acad., VI. p. 217, 
1884) resembles, as already stated by Professor Verrill, the descriptions and 
figure of D. candidum. 
Dentalium striolatum Srımr. 
One living specimen, Station 329, off Cape Lookout, N. C., in 603 fathoms. 
A very abundant species found by the U. S. F. C. from Flemish Cap to off 
Cape Hatteras, N. C., in 6 to 1,255 fathoms; not living in less than 35 fathoms. 
Dentalium occidentale Srimp. 
VERRILL, Trans. Conn. Acad., V. pl. 42, figs. 16-18, 1882. 
Nine living and seven dead specimens, Station 329, off Cape Lookout, N. C., 
in 603 fathoms. Four living, Station 336, off Delaware Bay, in 197 fathoms. 
An abundant species found by the U. S. F. C. from east of Banquereau to 
off Cape Hatteras, N. C., in 26 to 1,356 fathoms; not living in less than 51 
fathoms. Recorded by Mr. J. F. Whiteaves from the Gulf of St. Lawrence. 
Siphodentalium vitreum M. Sans? 
VxRRILL, Trans. Conn. Acad., V. p. 557, pl. 42, fig. 19, 1882. 
One dead specimen, Station 325, off Cape Fear, N. C., in 647 fathoms, 
A very rare species found by the U.S. F. C. from south of Martha's Vine- 
yard to Chesapeake Bay, in 368 to 811 fathoms ; not living below 368 fathoms. 
Also recorded by Mr. J. F. Whiteaves from the Gulf of St. Lawrence. 
The above specimen has been broken and evidently repaired by the animal, 
so that it is somewhat distorted, and does not agree perfectly with authentic 
specimens of this species from the north. 
PTEROPODA, 
Cavolina tridentata (Forskät). 
VxnniLL, Trans. Conn. Acad., V. p. 554, figs. 6, 7, 1882.

dead, Station 308, east of George’s Bank, in 1,242 fathoms. A fragment, Station 
321, off Charleston, S. C., in 233 fathoms. Four dead specimens, Station 325, 
off Cape Fear, N. C., in 647 fathoms. One dead, Station 336, off Cape Fear,
