On the Literature. 



On this topic very little need to be said. During the years [899 101 ; .1 series ol verj important 

 papers have been published by G O. Sars, W. T. Caiman, T. R. R. Stebbing and C. Zimmer. In his book 

 mi the Cumacea in "Das Tierreich", 39 Lief., [913, Stebbing has compiled and quoted the whole- literature 

 until 1912, and for this reason I have referred to his most useful hook in the synonymical list at every spe< ies 

 Zoologists wishing to get further knowledge on synonymy than the generally rather tew references in the 



sent paper can easily find them in "Has Tierreich". Zimmer's original contribution to the knowledge 



of the northern fauna is of slight importance, but his paper on the Cumacea in "Deutsche Siidpolar-Expedi- 



tion 1901—1903 Bd. XIV. Zool., VI, p. 438 491 (published in r.913) contains a very interesting chapter; 



"Zirkumpolaritat und Bipolaritat" (p. 183 488), in which an outline <>t the classification of families and 



'..\ followed by me is given, together with the number of species of each genus in the five climatic /ones

Results and Questions. 



A The Material. 



A comparison ol the Cumacea from the "Ingolf" area with the world's fauna of the same order may 



me interest. In 101 ; Stebbing states to have enumerated 509 accepted and 23 doubtful species; of 



the latti reat majority will certainly disappear as unrecognizable for ever or synonyms, and 



only ■ established since [91 ;. It we therefore put the total number of valid species 



Hit 1 . blished to [15, we must be near the truth. Compared with that number 66 species from the "In- 



rhaps somewhat more than might be expected. 



rrangement of families and then genera ol the world's fauna is that published by Zimmer 

 in i 'ln-r little from that adopted by Caiman, and Caiman's arrangement differs somewhat 



Zimmer accepted onlj 7 families, and it is very interesting that 6 ol these 



il the seventh family, the Ceratocumidae, only a single species 



idded that the large familj Bodotriidse, which has very few species in the cold areas 



is poorly represented in the 'Ingoli area, while the some-
