594 MR. E. A. SMITB ON SHELLS [JunC 2, 



both H. sebaeea and H. cerealis under examination, I have no hesi- 

 tation in pronouncing thein identical, 



16. Helix (Videna) saxct^ ann.e. (Plate XXXVI. figs. 7. 

 7 b.) 



Shell depressed-conoid, deeply umbilicated, very acutely keeled 

 at the periphery, light brown, sometimes with a few radiatin* pale 

 streaks on the upper surface, sculptured witli oblique lines of growth. 

 Whorls 5, rather slowly increasing, slightly convex, depressed and 

 margined above the suture, last not descending, compressed above 

 and below the keel, a little convex towards the umbilicus, which is 

 moderately large. Aperture transverse, flesh-tinted within. Peri- 

 stome simple, a little thickened along the basal margin, with the ex- 

 tremities united by a thin callus. Height 7 miliim. ; greatest 

 diameter 17, smallest 15. 



Hah. Santa Anna. " Living generally on the trunks of cocoa- 

 nut palms" (Guppy). 



This species is very like H. latimarginata. Smith, from the Fiji 

 Islands and Contrarietes Island, Solomon group ; but is a trifle 

 larger, more widely umbilicated, has a less convex spire, and a 

 broader body-whorl. The pale streaks on the upper surface are 

 like those in H. merziana, Pfr., but they do not occur in all ex- 

 amples. 



17. Helix (Rhytida) villandrei, Gassies. 



Hal. Ugi Island {Guppy); San Christoval {Maegillivray, Angas, 

 and Brazier). 



18. Helix (Cam^na) hombroni, PfeiflFer. 



Hab. Shortland and Faro Islands {Guppy) ; Ysabel Island 

 {Brenchley in Brit. Miis.) ; Solomon Islands {Hombron and Jac- 

 quinot). 



"Admiralty Islands," the locality originally assigned to this species, 

 is evidently incorrect. 



19. Helix (Chlorttis) evstotwa, Pfeiffer. 



Hab. Ugi and Faro Islands {Guppy) ; New Georgia {Macgil- 

 livray). 



With this species should be united H. erinaceus of PfeiS'er, for 

 having carefully compared the types of both forms, I do not find 

 any difl'erence, and therefore conclude that H. eustoma is another 

 instance of a species wrongly assigned to the Admiralty Islands. 



20. BuLiMus (Placostylus) cleryi, Petit. 



Hab. " The Koofeh district on the north coast of San Christoval" 

 {Guppy). 



This remarkable species varies considerably in form, some speci- 

 m.ens being much constricted round the middle of the body-whorl 

 and much more slender than others, which show no trace of irregu- 

 larity of outline. The type figured by Petit has a length of 100
