FUSING. 57 



M. Tapparone-Canefri thinks that this species approaches 

 rather too closely to a variety of F. polygonoides, Lam.; he thinks 

 F. pauper culus, Desh., may be the young of it. 



F. GRADATUS, Reeve. PL 35, figs. 123-125. 



Light yellowish or orange, the nodulous sculpture white. 

 Shell distinctly shouldered, covered by coarse rounded longi- 

 tudinal ribs, which are cut into compressed nodules by coarse 



revolving riblets. Length, 2 to 2*5 inches. 



West Indies. 



The species was described without locality, but the figure 

 corresponds exactly with specimens of F. Hartwigi, Shuttl. (fig. 

 124), which were collected at the island of St. Thomas, W. I. 

 F. Paeteli, Dunker (fig. 125), also described without locality, 

 appears to be the same. The latter species is compared by 

 Dunker with F. strigatus, Phil., with which, notwithstanding the 

 differences he has pointed out, it is entirely too closely allied. 



F. SCHRAMMI, Crosse. PL 35, fig. 130. 



Subtranslucent, finely striated with revolving lirae ; longitu- 

 dinaly, tuberculately costate ; with a median sharp angle or 

 carina, appearing on the spiral whorls also. Yellowish, with an 

 interrupted, pallid brown band. Length, 69 mill. 



Ghiadeloupe, W. I. 



This may possibly be the .young of an extreme variety of the 

 following species. 



F. DISTANS, Lam. PL 36, fig. 131. 



Whorls convex, carinate in the middle, and encircled by a row 

 of compressed tubercles. Light yellowish brown, the raised 

 revolving lirre darker, as are also the interstices of the tubercles. 

 Shell stout but rather light in texture. Length, 5 to 6 inches. 



Philippine Islands. 



Murex ansatus and versicolor, Gmelin, are probably the same 

 species, but I am unable to identify them positively. The fol- 

 lowing, however, can onty be separated by locality, and by its 

 usually more elate form although some are exactly like distans. 

 It may be advisable to treat it, for the present, as a variety.
