26 TRANSACTIONS OF THE WAGNER FREE 



channel close to and in front of the suture; transversely the sculpture is only of 

 lines of growth, which cover the whole shell, but are not prominent ; aper- 

 ture narrow, especially behind, posterior angle hardly notched, pillar straight, 

 simple. Max. Ion. of shell 27.5 ; of aperture 23.0 ; max. lat. of shell 13.3 mm. 



White Tertiary (Pliocene ?) limestones of the Island of Santa Cruz, West 

 Indies. 



This shell, now pure white, retains traces of yellow flammules on the spire, 

 radiating from the apex, and irregular yellowish blotches on the sides. 



This species is of entirely different form from C. plmiilirattis Sowerby, C. 

 gracilissimus Guppy, C. aratus Gabb and other Antillean sulcate cones. C. 

 Bonacsyi Gabb has also a widely different form, with the spire unstriated. I 

 judge of Gabb's species, of course, by his types at Philadelphia, as the fossils 

 have never been figured. I have had this species for a long time, and take 

 this opportunity of figuring it.

Miocene of North Carolina (Conrad) ; of Maryland (Meek) ; Pliocene of 

 South Carolina (Tuomey & Holmes) ; Caloosahatchie beds (Heilprin, Will- 

 cox, Dall, Burns and others). 



A larger series than was available to Prof Heilprin when he renamed this 

 species, has enabled me to conclude that C. Tryoni is merely the full-grown 

 and mcst perfect form of C. adversarius. The shell is remarkably variable in 

 form and in its sculpture, which, never very strong, may be almost absent ; 

 the spire may be faintly coronated with tubercles on the carina or plain, the 

 carina may be sharp or gently rounded. Conrad's original figure is defective 

 in making the spire revolve in a nearly horizontal plane as in a dextral shell, 

 whereas it is always more oblique. 



Conus proteus Hwass. 



Conus proletis Hwass, Encycl. Meth., vers. i. part 2, p. 682, 17C9. Tryon, Man., vi. p. 12, pi. 



2, figs. 30-35, 1884. 

 Conus Berghausii? Gabb, Am. Phil. Trans, xv., 1873, p. 232 (not of Hoernes, Foss. 



Wiener beck., pi. i. fig. 3). 

 Conus Mercati? Heilprin, Trans. Wagn. Inst. I. p. 83, 1887 (not of Hoernes, Brocchi, etc.). 



Specimens collected by me on the Caloosahatchie retain the colors suffi- 

 ciently to leave no doubt as to their affinities with the recent cones of the 

 Florida coast and Antilles, with which they absolutely agree otherwise. I 

 have not seen Gabb's shells, but have no doubt they should also be referred 

 to Conus proteus, which for that matter has many other synonyms, and is 

 generally supposed to be Gmelin's doubtful Coitus spurius.
