392 LIST OF LAND SHELLS FOUND ON THURSDAY ISLAND, 



The specimen before me dredged at Bourail, New Caledonia, 

 by Lieutenant Heurtel, French Navy, answers in every respect 

 to the description of Sowerby. The interior is far before those 

 known to Reeve and Sowerby, it is of a fine rich salmon colour, 

 bordered with dark mauve, having the anterior edge white ; 

 posterior end bordered with light mauve, forming a margin round 

 the lower edge. The rich colour may be compared to the salmon 

 mauve and rose pink Ttigonia Lamarchii, Gray.

During a short visit paid by Mr. C. E. Beddome, in 1877 to 

 Thursday Island, one of the Prince of Wales Group in Torres 

 Straits, he obtained six species of Land Shells ; he sent me at the 

 time a number of specimens I herewith give the list and describe 

 two new species.

Very fine specimens were obtained at Darnley Island, Torres 

 Straits, during the Chevert Expedition to New Guinea ; when 

 described by Dr. Cox, he only had one specimen. The Thursday 

 Island examples (6), are of a pale horny green not having the 

 fine rich gloss that is found ou the Darnley examples.
