to be reconsidérée!. Gonsequently I examined the fine collection 

 of Euphausiacea in the Copenhagen Muséum, determined the 

 majority of the spécimens of the same order captured by the 

 Siboga, inspected some of the Schizopoda collected by the 

 Swedish Antarctic Expédition, and studied Dana's old work.The 

 resuit was that I resolved to write a second treatise. My chief 

 purpose in doing so is to put a stop to several errors introduced 

 by Sars in 1 885 and adopted by ail subséquent writers, but 

 seizing the opportunity I correct a few other points and describe 

 or mention some species not dealt with in my former paper. 

 Most of the forms dealt with in this second note are represented 

 in the Monaco collection, but some other species are embodied 

 for the sake of comparison. 



Before entering the discussion of the species some particu- 

 lars may be mentioned. It is not my intention to enumerate ail 

 the species received in March; the majority of them is identical 

 with those dealt with in the former paper, and though in most 

 cases the number of spécimens is strongly increased and a few 

 or many stations could be added, this addition to our knowledge 

 of their geographical distribution would yet be of slight value, 

 because nearly ail the stations new for each species are found 

 in the same triangle, the angles of which are the Banc de 

 Gorringe, the Azores and the Canary Islands. In the former 

 paper I enumerated 25 species of Schizopoda, and the existence 

 of one species more was indicated; in the new material I fmd 

 many spécimens of the last-named form and besides same other 

 species; the total amount of Schizopoda collected in 1904 is 32, 

 verily a very large number. (For various reasons two of the 

 new forms are omitted in this paper). 



I beg Dr. W. T. Caïman, Mr. E. W. L. Holt and Miss Mary 

 J. Rathbun to accept my sincère thanks for services kindly 

 rendered me and mentioned in the discussion of some of the 

 species.
