XL CRUSTACEA. 



By T. V. HODGSON. 



(Plates XXIX-XL.) 



Foe the opportunity of examining the collection of Crustacea 

 brought home by the 'Southern Cross' Expedition, I am indebted to 

 Professor F. J. Bell, and I am much more indebted to him for his 

 kind assistance and advice during the progress of the examination. 

 The collection came to me in about sixty bottles, for the most part 

 of two-ounce capacity. The state of preservation of the specimens is 

 a matter which calls for some comment; as a rule, far too many 

 specimens were crammed into one bottle, the result being that they 

 arrived at the Museum in a more or less macerated condition ; some 

 were very bad. 



A summary of the results may be expressed as follows : — 



Decapoda .... 6 genera, 6 species, including 1 new species 

 Schizopoda .... 1 „ 2 „ „ 2 „ „ 



Isopoda 7 „ 10 „ „ 10 „ „ 



Pycnogonida .... 1 „ 1 „ „ 1 „ ,, 



Cumacea 1 „ 1 „ 



Copepoda , . . . 2 ,, 2 ,, 



With regard to the Amphipoda, I sincerely regret that my duties 

 have prevented me from seriously dealing with this group. 



A preliminary examination has been made, and the species 

 roughly sorted out; from this I should assume that there are 

 upwards of thirty-five species in the collection, and that at least 

 twenty-five will prove to be new. This group then, as might have 

 been expected, is the most important of the Arthropod phyhim.^ 



The Cumacea was represented by a single mutilated specimen 

 from Cape Adare, and I am unable to assign even its generic rank. 

 Two genera of Copepoda were found in a bottle containing an 

 assortment of specimens, but they were so macerated as to be useless 

 for identification. They represented two genera of Calanids. It is 



' I am glad to say that Mr. A. C). Walker has Idudly undeitaken to examine 

 it.— F. J. B.
