4 W. M. TATTERSALL. 



the British Museum material, and provided me with valuable notes as a result, which 

 I have freely used in this report. The Rev. T. R. R. Stebbing, F.R.S., placed two of 

 the type specimens of Euphausia vallentini at my disposal, with full permission to 

 dissect them if found to be necessary, while Prof. D'Arcy W. Thompson, C.B., 

 allowed me to examine and retain for some time a small collection of Antarctic 

 Schizopoda from the collections of the Museum at University College, Dundee. I am 

 specially indebted to Dr. Hansen, of Copenhagen, for the most generous and valuable 

 assistance. Not only did he kindly confirm or modify my determinations of the 

 more subtle species of Euphausia, but he placed at my disposal his notes and drawings 

 of the male copulatory apparatus of the species of this genus, of which he has made 

 a special study. Without his help I should have failed to recognise that the two 

 specimens of Antarctomysis belonged to two distinct species, while I should have 

 recorded as E. lucens the new Antarctic species which Dr. Hansen will himself describe. 

 For all this assistance I wish to express my best thanks.
