RISSOINA. 383 



R. Jickelii, Weinkauff (fig. 4), R. Blanfordiana, Nevill (fig. 3), 

 R. Hungerfordiana, Nevill (fig. 2), R. Seguenziana, Issel (figs. 97, 

 98) and R. strigillata, Gould (figs. 100, 1), as figured by Wein- 

 kauff, are synonyms ; whether the latter really represents Gould's 

 species is extremely doubtful. 



R. BELLULA, A. Ad. PL 57, figs. 93, 85. 



Semipellucid, white, with strong, distant spiral ribs, nodose at the 

 intersection of usually closer and smaller, longitudinal lirse ; whorls 



8, slightly convex ; lip produced below, externally crenulately 

 varicose. Length, 5 mill. 



Philippines. 



R. nitida, A. Ad. is apparently identical, but the figure of it 

 given in Reeve's Iconica (fig. 85), looks very like the next species. 



R. NODICINCTA, A. Ad. PI. 57, fig. 94 ; PI. 58, fig. 7. 



White, with long spiral riblets, generally two on the spire 

 whorls, three or four on the body whorl, the upper ones strongest, 

 nodulous at the crossing of distant longitudinal riblets ; whorls 9- 

 10, biangular, with deep suture; lip flexuous, varicose. 



Length, 10'6 mill. 



Philippines, New Caledonia. 



The latter locality is that of R. hystrix, Souverb. (fig. 7). 



R. GRANULOSA, Pease. PI. 58, figs. 12, 5. 



Solid, white, shining, with three spiral rows of tuberculated ribs 

 on each whorl, and two additional, smaller rows on the lower part 

 of the body whorl, crossed ,by distant longitudinal riblets ; whorls 



9, slightly convex, closely striate in the interstices, suture deeply 

 impressed, base with a funicular rib ; peristome thick, somewhat 

 dilated. Length, 8'5 mill. 



Sandwich and Viti Is. 



Pease's single specimen was a juvenile, with four whorls. The 

 above description is taken from that of -R. sculptiUs, Garrett (fig. 5). 

 The species may prove to be a variation of R. nodicincta. 



R. HORRIDA, Garrett. PL 58, figs. 8, 11 ; PL 68, fig. 11. 



Thick, white, with distant clathrate ridges, the intersections 

 nodulous, the interspaces deep, in spiral scries there are two or 

 three ridges on the upper whorls, and four on the body whorl, be- 

 sides the basal luniculum ; lip varicose, rather widely channeled in 

 front. Length,? 7 mill. 



Viti /*., Port Curtis, Australia.
