 84. — S. coiuavus Desh. Cat. des Moll, de I'lle de la Reunion, 1863, 

 P- 34, pl. 5- figs- I, 2. 

 Hab. : Reunion Island. 

 Described from two lower or right valves only. 



85. — S. fauroti Jousseaume. Mem. Soc. Zool. Fr., 1888, i., p. 221. 



Hah. : Red Sea. 



Described from two odd valves; no figure is given or any com- 

 parison made with other species. 



86. — S. lo7igitudinalis Lamk. Anim. Sans Vert., vi., 181 9, p. 19.1. 



It is doubtful whether this species can be identified ; the type 

 specimen was in the Dufresne Collection, which has probably been 

 distributed and the types lost sight of. Lamarck referi-ed with doubt 

 to the figures in Chemnitz, Conch. Cab., vii., pl. 45, figs. 466, 467, 

 which probably represent ^V. gaderopus. 



The figure given by Chenu, Illust. Conch , pl. 9, fig. i, is quite 

 different from those figured by Sowerby, Thes. Conch., figs. 23, 25, 

 and 56, and Reeve, Conch. Icon., fig. 46, all of which are to me varie- 

 ties of ustulatns Reeve. I have received a photograph of the shell 

 figured by Chenu, which is now in the Geneva Museum; the authori- 

 ties there cannot say with any certainty that it is the actual type 

 specimen. 



87. — S. plicatiis Linne. Systema Naturae, 1767, p. 1136, no. 153 

 (not S. plicatus Munster, apud Goldfuss Petr. (fossil) pl. 106, 

 figs. 7A, B, 1826-1864). 

 Hab. : Java. 



All the figures referred to by Linne represent very worn specimens 

 resembling coccineus and ideriats.
