"Descriptions of 4 New species of Helix; with some 

 notes on Helix Angasiana of PfeifFer." — By George French 

 Angas, F.L.S., C.M.Z.S., F.R.G.S., &c. 



P. Z. S., Feb 15th. 1876, pp. 264 — 268. 



Helix beatrix (pi. XX. figs. 1 — 5.). Solomon Archipelago. This 

 shell, like Helix meta, Pfr. is very variable in color, five varieties 

 being enumerated, ranging from pellucid white to dark purplish 

 chocolate or rich orange. It may be readily separated from 

 Helix meta by its smaller size, more convex whorls, and rounder 

 aperture, in which the subflexuous outer lip and diagonal form 

 of Helix meta are wanting. The outer lip is also much less 

 expanded and reflected, the texture less glossy and shining. 



Helix Ramsdeni (pi. XX, figs. 6, 7.). Solomon Archipelago. Some- 

 what allied to Helix Boivini, Petit, ( H. subrepta, Quoy,) but 

 the whorls are more rounded, the last whorl smaller, and the 

 shell generally more conical. The peculiar white spots on the 

 central black band remind one of similar markings in H. ambrosia, 

 Angas. The scarlet outer lip so constant m.H. boivini is entire- 

 ly absent in the present species, and the shell is of a bluish white 

 color. 



Helix Moresby i (pi. XX, figs. 8, 9.). Port Denison, Northern Queens- 

 land. Approaches most nearly Helix Yulei, Forbes, but is 

 larger, much more conical, with the base of the whorl peculi- 

 arly flattened. 



Helix rhoda(\A. XX, figs. 10 — 12). San Christoval, Solomon Archipel- 

 ago. This species belongs the Trochomorpha group, its nearest 

 ally being Helix merziana, Pfr. 



Helix Angasiana, Pfr. (not Newcomb). Originally described in 1862 

 by Dr. Pfeiffer in the "Journal de Conchyliologie" from a dead 

 and bleached specimen sent to him by Mr. Angas, from the 

 neighborhood of Lake Torrens, South Australia. On obtain- 

 ing living and unbleached specimens, the amended description 

 was publishedinthesamejournalbyMrAngasinT863. Dr. Cox 

 of Sydney, however, still regards Pfeiffer's original description 

 "Solid, white andporcellanous" as the normal state of H Angasia- 

 //# and gives H. Angasiana not Pfeiffer, referring to the amended
