THE 



VOYAGE OF H.M.S. CHALLENGEE. 



ZOOLOGY. 



REPORT on the Schizopoda collected by H.M.S. Challenger during the Years 

 1873-76. By Professor G. 0. Sars of the University of Christiania. 



INTRODUCTION. 



Of the very extensive collections of Crustacea made during the Challenger Expedition, 

 the two interesting groups, the Schizopoda and the Cumacea, have been placed in 

 my hands, by Mi\ John Murray, for examination and description. 



In the present Report only the first of these groups, the Schizopoda, is treated of. 

 The Cumacea will subsequently be described and figured in a separate Report, which will 

 be issued as soon as possible, and to which will be appended a short Report on the 

 Challenger Phyllocarida. 



The collection of Schizopoda procured during the long voj^age of H.M.S. Challenger 

 has turned out extremely rich and of very special interest, containing, as it does, several 

 most remarkable new types, the examination of which has led to a much fuller compre- 

 hension of the morjihology of the Schizopoda and their relation to other Crustacea than 

 we previously possessed. The various collections having been made in widely distant 

 tracts of the ocean, an important contribution to the geographical distribution of species 

 has likewise been acquired. 



Very special regard had already Ijcen paid to this interesting group of Crustacea by 

 the late Dr. R. v. Willemoes-Suhm, whose untimely death, during the Expedition, was 

 so deeply deplored by his friends and the scientific world. 



In a very interesting treatise on the Atlantic Crustacea from the Challenger 

 Expedition, that appeared in the Transactions of the Linnean Society of London,' 



' Trans. Linn. Soc. Land. (Zool.), ser. 2, vol. i. p. 2:$, 1875.
