TAPHON, STREPTOSIPHON. 143 



F, CANALICULATUS, Linn. PL 57, figs. 394, 395; PI. 58, fig. 401. 

 Fulvous ash-color, covered, when fresh, by a light yellowish 

 brown pilose epidermis. Length, 5-7 inches. 



Cape Cod, Mass, to Florida. Fossil, miocene to postpliocene. 



The tubercles become obsolete on the body-whorl of the adult 

 shell. Animal with white mantle, edged with a narrow, bright 

 yellow granulous cord ; proboscis long, black-tipped, reddish 

 near the body. A string of the ovicapsules from Atlantic City, 

 N. J., contains ninety-eight embryos in each capsule, making 

 about five thousand for the entire string. 



F. PYRUM, Dillw. PL 58, figs. 402, 403. 



Whitish, conspicuously longitudinally flamed with light chest- 

 nut or orange ; aperture whitish or yellowish within. 



Length, 4-5 inches. 



Florida. 



Whorls carinated, but scarcely tuberculated at the angle of the 

 shoulder. Mr. Conrad maintained that his F. plagosus is a dis- 

 tinct species, but I am not able to separate it. 



Submenus Taphou, H. and A. Adams. 



Dr. Gill eliminates this from Fulgur, with which he says it 

 evidently. has no affinity. I have not seen the shell, but judging 

 from description and figure I would suppose it to be either 

 related to Ficus or to Fulgur, and probably much closer to 

 Ficux. * 



F. STRIATUS, Gray. PL 58. fig. 404. 



Whitish, streaked longitudinally with orange-brown ; interior 



of aperture white. Length, 1*6 inches. 



China. 



Genus STREPTOSIPHON, Gill. 



S. PORPHYROSTOMA, Adams and Reeve. PL 58, tigs. 405, 406. 



Whitish, with a yellow-brown epidermis, marked obsoletely 

 with spiral brown lines ; aperture white or light purple. 



Length, 38 mill. 



Eastern Seas, Senegal. 



S. recurva, A. Adams (fig. 406) is evidently the same species.
