Rfjuarka. — This species has only been recorded fx-oni 

 Port Jackson (depth not stated). Although Thompson 

 (1909, page 533) suggests that this specimen belongs to the 

 genus Eurycyfh, nevertheless the slender bodv, the large 

 proboscis, and the simple scape of the chelophores, put it 

 undoubtedly in the genus Aworhynchus.

This genus was first defined by Haswell. IIis descrip 

 tion is as follows: — 



" Fimt pair of appindayes ivfll developed, chidiforvi, 

 " secmid pair tirlL devflopfd, palpiform n'iih nine joint x. 

 '' Third pair icith seven jointii, none oj Uitm provided with 

 " CO II, pott nil spiufs." 



In 1887 Schimkewitsch obtained another species (N. 

 korotntwi) referable to this genus, and by comparing the 

 charactei-3 of his own species with Ifaswell's description of 

 N. armatus, came to the conclusion that Haswell s speci- 

 men was immature. Schimkewitsch therefore re-defined 

 the genus as follows : — 



" Ce yeurt' pn scnfe les niandibitles (I.) iriariicufcet!, pas 

 *' chcliftnmeH, les extremifes II. 10 articulieii, les exirenii/.es 

 " 111. 10 articuli'es, privees du crochet el des epines pliiini- 

 ^^ formes, V article tar sale (8) des exlremites IF. - VII. est 

 "7ntini dipini'is basulfs et de crochets secondaires lout H Jait 

 " radimeuiairts (an mains chez notre ecpcce)." 



Loman's (1908) definition goes much further, and in 

 substajice is as follows: — 



" Body segments qnite coalescent, lateral processes separate 

 " Proboscis hirye, thick, arid moveable ; chelifori delicate, shaft 

 " ttco jointed, jiincers delirate, occasionally rudimentary in 

 " older animals. Palps nine jointed, second and fourth joints 

 " I'luyest, the remainder short. Ovigers of male slender, Jourth 

 ^^ joint very long also the second and fifth, distal joints tmall, 

 '' terminal joint long. No toothed spines, only hmrs or plates.
