370 RISSOINA. 



R. CONIFERA, Schwartz. PL 55, fig. 30. 



Somewhat solid, subpellucid, shining, white, with 12-1 4 rounded, 

 subdistant, straight longitudinal ribs, the interstices closely spirally 

 striated below ; whorls 6-7, turrited, suture crenulated ; lip varicose. 



Length, 5*4 mill. 



Mauritius. 



Described by Schwartz and referred to R. conifera. Montagu, a 

 lost species which is more likely to have been a R. Bruguieri. 

 Weinkauff erroneously quotes it as R. coniformis and gives it the 

 new name R. Montagui. 



R. FASCIATA, A. Ad. PI. 55, figs. 17, 18. 



Solid, chestnut color, with a central pale band, distantly obliquely, 

 subflexuously plicate, closely spirally striate; whorls 8, somewhat 

 convex, with impressed, crenulated suture. Length, 6'8 mill. 



Sydney, Australia. 



R. Smithii, An gas, (fig. 18) is a synonym. 



R. BRUGUIERI, Payr. PI. 55, figs. 19, 22. 



Solid, w r hite or yellowish white, with about 16 flexuous, longitu- 

 dinal plicae, crossed by strong spiral striae; whorls 7-8, a little 

 convex, suture plane, somewhat undulated; varix ridged. 



Length, 7'6 mill. 



Mediterranean Sea. 



R. Poliana and R. reticulata, Risso, and R. decussata, Menke are 

 synonyms ; and R. striolata, Risso (fig. 22) may probably be added. 



R. HANLEYI, Schwartz. PL 55, fig. 21. 



Strong, shining, milk white, with two orange-brown bands, with 

 22-24, close, subsinuous, low, longitudinal plications, and close, 

 numerous spiral striae, the sculpture evanescent on lower part of 

 body whorl; whorls 7, slightly convex, with impressed suture; lip thick- 

 ened, scarcely varicose. Length, 7'3 mill. 



Philippines', Sydney, Australia. 



R. VAIMKCJATA, Angas. PL 56, figs. 43-46. 



Varies greatly in coloring as well as in the development of its 

 sculpture. I think that the figures which I have copied from the 

 Conch. Icon, are from worn specimens, us they do not exhibit the 

 .sculpture to the same extent as Annas' originals, the description of 

 this species is not unlike that of //. Jhin/i'i/I, and it will probably 

 prove identical with it.
