60 ME. THOMAS SCOTT ON THE 



E-eport on the Marine and Freshwater Crustacea from Franz- 

 Josef Land, collected by Mr. William S. Bruce, of the 

 Jackson-Harmsworth Expedition. By Thomas Scott, 

 F.L.S., Naturalist to the Fishery Board for Scotland. 



[Eead 15th December, 1898.] 



(Plates 3-9.) 



Theough the kindness of Mr. W. S. Bruce I have had the 

 privilege of examining the Crustacea which he collected in Franz- 

 Josef Land during his sojourn there in 1896 and 1897. 



It was with some hesitation that I undertook the examination 

 of this interesting collection. Fortunately, however, a large 

 number of the organisms contained in it were already more 

 or less familiar to me, either as recent or fossil species, and. 

 therefore the examination, though arduous, was less so than it 

 would otherwise have been. Prof. Gr. S. Brady and the Eev. T. 

 K. R. Stebbing have kindly assisted me with the identification of 

 certain doubtful species ; while my son, Mr. Andrew Scott, gave 

 me valuable help with the examination of the Copepoda, and 

 by the preparation of a number of drawings necessary for the 

 elucidation of some apparently new forms, and for the confirma- 

 tion of others which, though already described, have not before 

 been recorded from the Arctic seas. 



It was necessary, in describing the results of my examination, 

 to adopt some recognized method in classifying them, and the 

 general arrangement which I have followed is that proposed by 

 the Eev. T. E. E. Stebbing in his ' History of Crustacea,' * and 

 exhibited in the synoptical table at page 49. In this table the 

 Crustacea are divided into four Subclasses, viz. : the Malaco- 

 STEACA, Entomosteaca, Gigantosteaca, and Thtbosteaca (or 

 Cirripedia). The collection of Crustacea made by Mr. Bruce 

 has been found to contain representatives of the first, second, 

 and last of these Subclasses; and I now proceed to indicate 

 briefly the number of the species that belong to each of these 

 three subdivisions. 



(1) The Malacosteaca. 



The Malacostraca, which comprise what are otherwise called 

 the higher Crustacea, are still further subdivided into the two
