Mr. A. Goldie, a trader and collector, travelled extensively 

 in south-eastern New Guinea, and collected land and marine 

 shells j that went mainly to the British Museum, and were 

 described by the late E. A. Smith in the Annals and Magazine 

 of Natural History. Professor A. C. Haddon, during his 

 expedition to Torres Strait, on 17th August, 1888, dredged 

 in the channel between Saibai and New Guinea. His molluscan 

 gatherings were submitted to Messrs. MelvHl and Standen, who 

 published their results in the Journal of the Linnean Society, 

 London, vol. xxxvii, 1899, pp. 150-206, with two plates. 



A collection made by Sir William Macgregor in the 

 Louisiades in 1889 was also sent to the conchologist of the 

 British Museum for naming and describing. In 1890 Mr. Charles 

 Hedley of the Sydney Museum was in New Guinea for three 

 months, the guest of Sir William Macgregor. He was given 

 opportunities to visit Milne Bay, Samarai, Port Moresby^ 

 and St. Joseph's River, mainly in search of land shells. His 

 gathermgs are described in the Proceedings of the Linnean
