F. LONGissiMUS, Gmel. PI. 34, fig. 120. 



Shell white, covered sometimes by a A^ery light brown 

 epidermis ; angle of each whorl bearing about ten rather large, 



compressed nodules. Length, 1*5 to 9 inches. 



Gciilon. 



F. crindidus, Gmel., ajipears to be the same species and has a 

 prior position in the " Systema," although published on the same 

 page ; I use longissimus preferably because it Avas adopted b}- 

 Lamarck, and the species is, consequently, much better known 

 under that name. 

 F. UNDATXTS, Gmel. PI. 32. figs. 121, 12(). 



Shell heavy, white; nodules more prominent, not compressed, 

 and fewer than in F. Jongi.'if'imuii, being 1 or 8 to the whorl ; 

 revolving stria' not so [)rominent. Length, to 7 inches. 



Central Polynesia. 



This species resembles the preceding, but the characters given 

 above M'ill serve to distinguish it. It is a ver}' ponderous shell, 

 and has an obsolete angle on the periphery below the shoulder 

 line, making the bod^^-whorl somewhat biangulate. 



F. similis, Baird (fig. 126), from Xew Caledonia appears to be 

 the same species, only differing in having "about 10 or 11 " 

 nodules in the specimen described. 



F. POLYGONOiDES, Laui. PI. 35, figs. 127, 128. 



Light brown, spotted and strigate with chestnut-brown ; bod}^- 

 whorl distinctly biangulate; both angles nodulous, those of the 

 shoulder the most prominent. Length 2*5 to 3-5 inches. 



East Indies. 



I figure two examples of this species, the proportions varying 

 considerably. It is possible that the succeeding species may be 

 only a ver}'^ slim variety, yet I am inclined to consider it distinct. 



F. LKPTORHYNonus, Ta])parone-Canefri. PL 35, fig. 129. 



Whitish, more or less strigated with reddish Itrown. 



Length, 3 inches. 



Red Sea. 

 See remarks under /''. pohjgonoides^ above. 



F. STRiGATUS, Phil. PI. 35, fig. 122. 



White, sharply angulate at the shoulder ; longitudinal ribs 

 prominent, chestnut-brown. Length, 2 inches. 



Red Sea? Australia ?
