Dana formed the opinion that Nebalia and Chirocephalus should be regarded as 

 representative genera of two families in a common tribe. Claus considered that Nebalia 

 could best be placed in a special group Leptostraca, between the Malacostraca and 

 the Entomostraca.

 by Kniyer, Claus, Metschnikoff, Packard, and others will be found in the Fauna 

 Norvegiae or the Challenger Phyllocarida. 



The specimens obtained by Dr Willey appear certainly to belong to this wide- 

 ranging species. One set were labelled " Crustacea, etc. that feed on dead fish, etc. 

 in the fish-traps. Lifu, Sandal Bay." Of these the largest scarcely exceeded a length 

 of 6 mm., and many were much smaller. Another set came from Blanche Bay, New 

 Britain, and were taken from (10 fathoms. Of these the largest reached a length of 

 7'5 mm. Baird gives a length of three-eighths of an inch for British specimens. Sars 

 speaks of the species reaching a length of 12 mm.
