P.Z.S., 1876, pp. 488 — 490 and plate xlvii. 



Helix malantensis (figs, i, 2, 3). Malanta Islands, Solomon 

 Archipelago. 



A trochiform species, differing from H. Guadalcanarensis, 

 Cox, in being more conical, the aperture smaller, with the outer 

 lip much less flattened and expanded, as well as by the absence 

 of the black margin at the angle of the reflexion, behind the 

 outer lip, and the purple spot on the columella, and in hav- 

 ing the base broadly stained and zoned with chesrtut. 



Helix Comriei (figs. 4, 5). Shores of Huon Gulf, South-east New 

 Guinea. 



This is allied to H. Brumeriensis, Forbes, but is smaller, 

 without the black lip of the latter. Dr. Comrie also obtained 

 several specimens of H. Brumeriensis at the same place, only 

 known hitherto by the single specimen in the British Museum, 

 collected by the late Mr. J. Mc.Gillivray at Brumer Island, 

 during the voyage of H.M.S, Rattlesnake in 1849. 



Helix robillardi {^g%. 6, 7). South-west Madagascar. 



Helix feneriffensis (figs. 8, 9). Feneriffa Islands, north-west 

 Madagascar. 



Helix eyrei (figs. 10-12). Shores of Lake Eyre, Central Australia. 



This species belongs to the group of discoidal Helices from 



the arid regions of South Australia to which, Arthur Adams 



gave the name of Anga sella, and to which H. cyrtopleura, Pfr., 



and H. Phillipsiana, Angas, also belong.
