STNTSTRALTA. 



Not figured, and no dimensions given. The coloration pre- 

 cludes its being a Fusus I suppose, but the description does not 

 indicate its true generic position. 



F. USTULATUS, Reeve. PI. 39, fig. 170. 



Rusty brown; whitish within. Length, 2*75 inches, 



Hab. unknown. 



In the partial separation of an inner lip from the columellar 

 margin of the canal, and in the canal being wide and open this 

 species possesses characters which remove it from the typical 

 Pusi and connect it with two shouldered species, F. proboscidi- 

 ferus and F. ventricosus. It is possible that these may form a 

 new generic group. 



F. PYRULATUS, Reeve. PI. 39, figs. 171, 172. 



Yellowish brown. Length, 2*75 inches. 



Van Diemari's Land. 



Appears to be somewhat immature. I have not seen the 

 species. 



Subgenus Sinistralia, H. <fc A. Act. 



F. MAROCCENSIS, Gmel. PL 40, figs. 173, 174. 



Yellowish white to light brown. Length, *75 to 1 inch. 



Isl. of Guadeloupe, W. Indies? 



The ribs are not continuous to the sutures, below which a 

 smooth space intervenes ; in the smaller specimens this space is 

 very narrow and thus may escape observation, but in better 

 grown individuals it becomes wider and more marked. In the 

 latter state Mr. Reeve has called the species F. elegans (fig. 174 ) : 

 a name which cannot stand even as a variety. The locality given 

 is exceedingly doubtful. 



Doubtful and Spurious Fusidas. 



F, LINCOLNENSIS, Crosse. PL 40, fig. 175. 



Whitish, with a wide central brown band. Length, 19 mill. 



York Peninsula, Australia. 



The coloration and very short canal remove this species from 

 Fusus; yet I do not know where to locate it. Resembles a 

 Muricidea.
