692 THE LAND MOLLUSCAN FAUNA OF BRITISH NEW GUINEA, 



E. A. Smith, of the British Museum, to compare my Papuan 

 specimens with Pfeiffer's types, I received from that gentleman 

 the following courteous reply : — " The two specimens of Succinea 

 from Mita, Milne Bay, are a trifle shorter than the types (3 speci- 

 mens) of S. simplex, Pfr., and are more amber in colour, but they 

 agree in the latter respect, and also in form, exactly with another 

 series of specimens from Treasury and Shortland Islands, Solomon 

 Group, which I identify as a form of simplex" Since the expe- 

 riences of Mr. Brazier, Dr. Guppy, and myself agree in finding this 

 mollusc in the taro gardens, it may perhaps be introduced with 

 this vegetable from island to island. 



I am also indebted to Mr. Smith for the information that my 

 species Helicina insularum (ante, p. 113) is identical with H. 

 suprafasciata, Sowerby (Conch. Icon, xix., Helicina, pi. xxx., 

 sp. 300), with whose types in the British Museum he has kindly 

 compared my specimens. Sowerby's types were not collected, as 

 stated, during the cruise of the " OuraQoa," but were received 

 from an island trader by Mr. Brazier, who after the return of the 

 " Curacoa " forwarded them to Mr. Julius Brenchley, by whom 

 they were presented to the national collection. That Sowerby 

 assigned the species to "Australia" (!) I offer as a sufficient 

 excuse for having overlooked his figure and description. 



An inspection of specimens in the Australian Museum labelled 

 Cyclotus Levis, Pfeiffer, collected at Mam Sound, Guadalcanar, 

 Solomon Archipelago, by Mr. Brazier, suggests that this name is 

 synonymous with, and takes priority over, G. tristis, Tapparone- 

 Canefri. This species (determined as levis) is described by Mr. 

 Brazier as being everywhere abundant, and unlike any other 

 shell known from the island. There can therefore scarcely be a 

 doubt that the shells collected by MacGillivray during the cruise 

 of the "Herald" in 1854, upon which Pfeiffer founded the species 

 (P.Z.S., 1855, p. 118), are similar to those quoted as "Guadalcanar 

 (MacGillivray in Brit. Mus.) " by Smith in the P.Z.S., 1885, p. 

 596. These he identifies with others collected in 1882 during the 

 cruise of the " Lark " by Dr. Guppy at Faro, Shortland and Santa 

 Anna Islands, and at Choiseul Bay in Bougainville Straits, Solomon
