218 A. JS. Verrill — MuUusca of the New Eiujland Coast. 



Length of the largest example, 6""" ; diameter of the oral end, 

 •8'""' ; posterior end, -S""". 



Station 2037, in 1731 fathoms; and station 2038, in 2033 fathoms. 

 (No. 35,142). 



These specimens are probably young, but difler from all of our 

 recognized s^iecies in the peculiar sculpture, in the form of regular, 

 microscopic, longitudinal striie. They may, however, prove to be 

 the young of D. capillosum J., which we have not yet recognized 

 among the specimens dredged on our coast. There is, also, a slender 

 shallow-water species, from off Cape Hatteras, which has, when 

 young, simihir tine striations, but the lines are not so numerous and 

 the shell is straighter. 



Dentalium, sp. h. 



Shell small, slender, nearly straight, or very gently curved. The 

 sculpture consists of fifteen to twenty narrow, elevated, angular i-ibs, 

 which diminish in size posteriorly and become nearly obsolete near 

 the tip ; auteriorh^ they are separated by much broader, clearly 

 defined, concave grooves, the scul2:)ture showing in reverse on the 

 interior surface. Oral aperture circular, somewhat oblique. Poste- 

 rior opening small, circular, squarely truncated. 



Length, 15"""; diameter at the oral end, 1-5"""; at the posterior 

 end, -8'"'". 



Station 2038, in 2033 fathoms, three specimens (No. 35,165). One 

 specimen, difl:ering from those described in being more slender and 

 having more numerous and finer longitudinal ribs, was taken at sta- 

 tion 2115, in 843 fathoms. 



These specimens are probably the young of one of the larger spe- 

 cies. They resemble the young of some of the varieties of I), occi- 

 dentale^ except that they are more slender and straighter. It is not 

 improbable, however* that they may prove to be forms of that vari- 

 able species. 



Siphodentalium teres Jeftreys. 



Jeffreys, Troc. Zool. Soc. London, for 1882, p. GGl, pi. 49, fig. 5. 



Station 2072, in 858 fathoms (No. 38,088) ; station 2084, in 1290 

 fathoms (No. 38,084) ; and station 2115, ott' Cape Hatteras, in 843 

 fathoms (No. 35,025). 



It was taken ott" the coast ol' Eui'ope by the Porcupine Expedition,
