SI STRUM. 191 



R. FUNICULATA, Reeve. PL 59, fig. 272. 



Bluish-white, ridges and tubercles black ; violaceous within. 



Length, '7 inch. 



Hab. unknown. 



R. PARVA, Reeve. PL 59, fig. 274. 



Whitish ; nodules orange-color and black in alternate rows. 

 Length, -3-* 6 inch. 



Philippine*. 



It is doubtful whether this species belongs here or in Peri 

 sternia. I have not seen authentic or undoubted specimens. 



R, SCABRA, Koch. 



Ovate fusiform, nodulous by decussating ribs and striae; with 

 three brown-black zones ; aperture as long as the spire, coarctate 

 with six equal teeth within the outer lip. 



Hab. unknown. 



I do not know this species ; it has not been identified or 

 figured by subsequent authors. 



R. LIVIDA, Reeve. PL 59, fig. 281. 



Chocolate-brown, variegated with darker color. 

 Length, 1 inch. 



Isle of Negros, Philippines. 



Ver}^ like Reeve's Buc. bimucronatum (which is a syn. of 

 R. ochrostoma), the principal difference being, that in this 

 species, the rib forming the shoulder forms a single angle, instead 

 of being double as in the latter. It is possibly a mere variety, 



R. CHRYSOSTOMA, Desh. PL 59, figs. 283, 279, 280. 



Light brown or yellowish ; orange or violet within the aper- 

 ture. Length, '75 inch. 



Ceylon, Seychelles, Mauritius, Polynesia. 



Reeve has figured a different species (= R. biconica) under 

 this name. I think that R. ozenneana, Crosse (fig. 279), 

 and Murex Crossei, Lienard (fig. 280), are merely varieties of 

 the same specific form, but I am unable to include (as Messrs. 

 G. and H. Nevill have done) Latirus gibbus. Pease ; the latter ap- 

 pears to be a true Turbinelloid species.
