London series of duplicates, containing about 225 species each : Prof. 

 George S. Brady, Sunderland, England ; Bev. A. M. Norman, Durham, 

 England ; Oxford University, Oxford, England ; Cambridge University, 

 Cambridge, England ; Boyal Academy, Stockholm, Sweden. 



In return for the London sets sent out, the following collections have 

 been promised, and, in one or two instances, have already been shipped 

 to us : From Professor Brady, a complete series, so far as practicable, of the 

 British free-swimming Copepods, a low Order of Crustaceans, forming 

 the chief food supply of many of our common surface-feeding fishes, 

 such as the mackerel, menhaden, &c. ; from the Eev. Mr. Norman, a 

 nearly complete collection of all the known British crabs, shrimps, and 

 parasitic Copepods, with other species of marine invertebrates ; from 

 the Boyal Academy of Sweden, portions of the Vega collections, made 

 by the Baron Nordenskiold, in the Arctic regions ; and from the Uni- 

 versities of Oxford and Cambridge, carefully-made preparations of 

 marine invertebrates for Museum display and the use of students. 



Negotiations for four of the remaining sets are now in progress with 

 the British Museum, the Imperial Museum of Austria, the Boyal In- 

 stitute of Natural History of Florence, Italy, and Prof. A. H. Malm, of 

 Gotlienborg, Sweden. The exchanges to be received for the London 

 series of duplicates will form valuable accessions to the Museum, and 

 amply repay the time and labor spent in preparing them. 



A fourth series of duplicates of Fish Commission specimens, called 

 Series IV, or Educational Series No. 2, is now in course of preparation, 

 and will consist of 200 sets, each containing about 120 species. This 

 series will be ready for distribution about March or April, 1884.
