[Plates I.-IX.] 



IHIS paper deals with a part of a rich collection of Cumacea belonging to the 

 Zoological Museum of Copenhagen, and entrusted to me for examination by the 

 kindness of Dr. F. Meinert and Dr. H. J. Hansen. It also includes a description of 

 some specimens sent to me from New Zealand by Mr. G. M. Thomson, which throw 

 light on species represented in the Copenhagen Collection. 



Altogether 30 species are dealt with, and of these 25 are regarded as new. The 

 majority of the species are derived from collections made in New Zealand and the 

 Gulf of Siam by Mr. H. Suter and Dr. Th. Mortensen respectively. There is no 

 ground for supposing that these localities are unusually prolific in Cumacea, and the 

 rich collections obtained there simply help to indicate how much remains to be done 

 by competent collectors in investigating the micro-crustacean fauna of shallow water 

 in tropical and southern seas. 



Among the more interesting of the forms described below attention may be called 

 to the remarkable new species for which I have established the genus Zygosiphon ; to 

 the very aberrant forms of Leuconidae comprised in the new genera Heteroleucon,
