2 Melvill and Standen, Report on Arctic Mollusca. 



H. J. Posselt* — the arrangement of whose nomenclature 

 we are now following — malacologists are well supplied 

 with literature of Arctic mollusca, and we feel there is but 

 little to be said with regard to Mr. Bruce's specimens 

 besides giving a mere catalogue, with exact localities. 



Mr. Walter Wellman has lately returned home (in 

 August, 1899), having completed the survey of the more 

 northerly parts of Franz-Josef Land, and giving the finish- 

 ing touches to the work of the Jackson- Harmsworth 

 Expedition, but we have yet to learn if any mollusca were 

 collected. 



A large proportion of the specimens are preserved in 

 formalin, a medium of which we are sorry to be obliged 

 to speak unfavourably as regards the calcareous covering, 

 — however valuable for the preservation of anatomical 

 parts — the shells being so frequently rendered fragile, and 

 much deterioration occurring owing to its corrosive action 

 on the carbonate of lime. 



Our best thanks are due to Dr. Hermann Friele, of 

 Bergen, and to Mr. Edgar Smith, of the British Museum 

 (Natural History), who have both aided us with advice 

 and examination of specimens. 



We may add that a few Nudibrmichiata were in the 

 collection, and also two or three Ptcropoda and Heteropoda, 

 but these are not dealt with in the present paper.
