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



Shell white, covered sometimes by a very light brown 

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



compressed nodules. Length, 7*5 to 9 inches. 



Ceylon. 



F. candidus, Gmel., appears 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 was adopted by 

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

 under that name. 

 F. UNDATUS, Gmel. PI. 32. figs. 121, 126. 



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

 and fewer than in F. longissimus, being 7 or 8 to the whorl ; 

 revolving striae not so prominent. Length, 6 to 7 inches. 



Central Polynesia. 



This species resembles the preceding, but the characters given 

 above will serve to distinguish it. It is a very ponderous shell, 

 and has an obsolete angle on the periphery below the shoulder 

 line, making the body-whorl somewhat biangulate. 



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

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

 nodules in the specimen described. 



F. POLYGONOIDES, Lam. PL 35, figs. 127, 128. 



Light brown, spotted and strigate with chestnut-brown ; body- 

 whorl distinctly biangulate; both angles nodulous, those of tho 

 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 very sliin variety, yet I am inclined to consider it distinct. 



F. LEPTORHYNCHUS, Tapparone-Canefri. PI. 35, fig. 129. 

 Whitish, more or less strigated with reddish brown. 



Length, 3 inches. 



Red tfe<t. 

 See remarks under F. polygonoides, above. 



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



White, sharply angulate at the shoulder ; longitudinal ribs 

 prominent, chestnut-brown. Length, 2 inches.
