76 FASCIOLARIA. 



blush or yellowish, with close, raised, red revolving lines, each 

 pair of which terminates in a marginal denticle. 



Length, 4-6 inches. 



Red Sea ; Ceylon ; Philippine Is. ; Australia ; Central Polynesia. 



F. ferruginea, Lam. (fig. 12), is only a slim form of this 

 species, in which the nodules are scarcely apparent. Occasion- 

 ally there are no nodules, the shell being scarcely shouldered : 

 this state has been described by Jonas as F. inermis (fig. 13). 



F. FUSIFORMIS, Valenciennes. PI. 61, figs. 18, 19. 



Upper whorls rudely, plicately ribbed, lower whorls with re- 

 volving striae or ridges only. Epidermis brown, under which 

 the shell is light brown. Length, 3-4 inches. 



So. Australia ; in grass wrack, 2 to 5 fathoms. 



I doubt whether this is more than an extreme form of the pre- 

 ceding species. 



F. ATJRANTIACA, Lam, PI, 61, figs. 20, 21 ; PI. 63, fig. 33. 



Rugose, tubercnlate on the shoulder, with occasional swollen 

 tubercles elsewhere on the body -whorl ; spirally grooved, the 

 grooves generally in pairs. Mottled reddish-orange and white, 

 under an olive or purple epidermis ; white within. 



Length, 3-5 inches. 



Coast of Brazil ? Cape of Good Hope ? 



Both localities are somewhat uncertain. The species is wider, 

 but closely allied to F. filamentosa, a few specimens of which 

 have a tendency to tuberculation below tKe shoulder, in the same 

 manner as in F. aurantiaca. F. purpurea, Jonas (fig. 27), is 

 founded apparently, on a specimen with epidermis. F. Persica, 

 Reeve, = clava, Jonas (fig. 33), is founded on the very ponder- 

 ous, adult form. 



F. CROCATA, Phil. PI. 61, figs. 22, 23. 



Shell yellowish, the revolving, elevated lines lighter in color. 



Length, 3-4 inches. 



Yucatan; Guiana. 



The original figure and description (fig. 22) are from a young 

 shell ; that of Kiister (fig. 23) represents a more mature speci- 

 men. The nearest species appears to be F. Jilamentosa which 

 is from an entirely different habitat. This species does not
