 and in exchange an equivalent in ethnological material has been sent. 

 A series of the bones of Rhytina was sent to Mr. J. W. Clark, of the

 land, in part exchange for some valuable skeletons received at the close 

 of the London Fisheries Exhibition in 1883. An exchange of mammal 

 skins has been made with Prof. Tycho Tullberg, of Upsala, Sweden. 



In addition to these exchanges correspondence has been carried on 

 with several museums with a view to arranging exchanges. Prof. S. 

 Hertzenstein, of the Imperial Zoological Museum in St. Petersburg, 

 Russia, has offered to send fishes and shells in exchange for American 

 fishes. Dr. A. Strauch, director of that museum, has been invited to 

 exchange Russian and Central Asiatic mammals for mammals from 

 North, Central, and South America. An exchange of fishes is being 

 arranged with Prof. T. Jeffery Parker, of the Otago University Museum, 

 at Dunedin, New Zealand. Dr. Serrurier, director of the National Ethno- 

 logical Museum of the Netherlands, in Leyden, has offered African eth- 

 nological material in exchange. 



The arrival of specimens of tin-bearing material, together with 

 systematic series representing the mode of occurrence and extraction, 

 and of mammals, from L. Wray, esq., curator of the Perak Museum in 

 the Straits Settlements, in exchange for mineralogical specimens, is 

 awaited with much interest. Professor Bernardin, of the Commercial 

 and Industrial Museum in the College of Melle, near Ghent, has been 

 asked to send samples of commercial products. D. Morris, esq., as- 

 sistant director of the Royal Gardens at Kew, in England, has made 

 application for specimens of American woods. These will be put aside 

 for that establishment as opportunity offers. Dr. Ernest Bayet, of 

 Brussels, has requested an exchange of fossils, desiring quaternary 

 ^ and pliocene material. In behalf of the department of Mollusks this 

 Museum has written to the director of the Cape Town Museum for a 

 series of land, fresh-water, and marine shells of that region, offering 

 in exchange any desired material. For the same department applica- 

 tion for a series of Storms shells has been made to the director of the 

 Brussels Museum. A letter has been addressed to Hon. St. John Lar- 

 nack, minister of marine Wellington, New Zealand, asking for speci- 

 mens in any department of zoology, an offer having been voluntarily 

 made to send us any desiderata which could be supplied, in return for 

 whitefish ova transmitted by the IT. S. Fish Commission. M. Milne- 

 Edwards, of the Museum of Natural History in Paris, has offered du- 

 plicate material from the dredgings of the Travailleur.
