4 THE VOYAGE OF H.M.S. CHALLENGER. 



During the "Transit of Venns " Expedition to Kergnelen in 1875, two species of 

 Serolis were obtained, which were figured and described by Miers, one of these — Serolis 

 septemcarinata — being new. 



About the same time the German ship " Gazelle " collected a number of species of 

 Serolis both at Kerguelen and on the shores of South America, which were described by 

 Studer' in 1879. This paper contains, besides the description of a new species (Serolis' 

 corimta), a few notes upon the habits of these animals and upon some points in their 

 anatomy. 



A few notes upon certain of the species of Serolis that are described in the present 

 Report are to be found in v. Willemoes Suhm's Preliminary Report ujjon the Crustacea 

 collected during the voyage of the Challenger.^ 



Finally, a recently published part of Bronn's Thierreichs (Bd. v. Abth. 2, Heft i.-x.) 

 contains a general account of the Isopoda by Prof. A. Gerstaecker, where some description 

 of the genus Serolis, especially of the geographical distribution, is given ; there are als(j 

 in this work a number of figures copied from the Memoirs of Grube and Studer ; and a 

 comparative view of the various schemes of classification of the order Isopoda ; for this 

 reason I have not in the present Report entered into any account of the systematic 

 positions which have been assigned to the genus Sei-olis by previous writers.
