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. sulcatwm Verrill (Trans, Conn. Acad., VI. p. 217, 
1884) resembles, as “already stated by Professor Verrill, the descriptions and 
figure of D. candidum.

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.

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 perteny, with authentic 
specimens of this species from the north.
