Turbonilla interrupta Adams, (p. 418.) 



H. and A. Adams, Genera, vol. i, p. 231, 1858 ; Gould, Invert., ed. ii, p. 231, fig. 

 001 (bad figure). TurritcUa interrupta Totten, Amer. Jour. Science, ser. i, vol- 

 xxviii, p. 352, fig. 7, 1835 ; Gould, Invert., ed. i, p. 268, fig. 173 (incorrect). 



Cape Cod to South Carolina. Quite common in Vineyard Sound and 

 Buzzard's Bay, in 3 to 10 fathoms ; Long Island Sound, off Thimble 

 Islands and New Haven, 3 to 5 fathoms, rather rare. Huntington 

 and Greenport (S. Smith). Dartmouth, Massachusetts (Adams). New- 

 port, Bhode Island (Totten). Fort Macon, North Carolina (Coues). 



I have received from Prof. E. S. Morse specimens of this shell ob- 

 tained from mud in the harbor of Portland, Maine, but they are dead 

 and bleached. I am not aware that it has been found living so far 

 north on our coast. Fossil in the Post-Pliocene of South Carolina. j 



Lov6n records this species as from the coast of Norway, but possibly 

 his shell is a different species, or else a variety of T. rufa of Southern 

 Europe, which is certainly very closely related to our species, and is con- 

 sidered the same by Jeffreys. If so, the name given by Totten has prece- 

 dence of rufa (Philippi, 1836). Farther and more extensive compari- 

 sons must be made before the identity of the two forms can be estab- 

 lished. 



The figure given in the first edition of Gould's Invertebrata, and copied 

 in the second edition, does not correctly represent this shell, and was, 

 perhaps, drawn from some other specieg, for it does not agree with 

 Gould's description, which is accurate. The spire, as represented, is too 

 acute and too rapidly tapered ; the last or body whorl is too large ; the 

 aperture has not the right form ; and the peculiar sculpture is not 

 brought out at all. Totten's figure, though somewhat coarse, is char- 

 acteristic. 



Turbonilla elegans Verrill. Plate XXIV, fig. 155. (p. 418.) 



American Journal of Science, ser. iii, vol. iii, pp. 210, 282, Plate 6, fig. 4, 1872. 



Shell light yellowish, elongated, moderately slender, acute. Whorls 

 ten or more, well rounded, not distinctly flattened ; suture rather 

 deeply impressed; surface somewhat lustrous, with numerous rounded 

 vertical costre, narrower than the concave interspaces, fading out 

 below the middle of the last whorl; and with numerous fine revolv.-
