Remarks. — This species has only been recorded from 

 Port Jackson (depth not stated). Although Thompson 

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

 genus Eurycyde, nevertheless the slender bodv, the large 

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

 undoubtedly in the genus Aacorliyndius.

This g-enus was lirst defined by Haswell. His descrip 

 tion is as follows : — • 



" Fiist pair, of appendages ivell developed, chelifortn, 

 ^^ second ^^air 'aeJL developjed, palpij'orm willb nine joints. 

 " Third jjair tviih seven joirits, nou,e of them provided with 

 "compound spines." 



In 1887 Schimkewitsch obtained another species {N . 

 korotnewi) referable to this g-enus, and by comparing the 

 characters of his own species with Haswell's description of 

 N. armatus, came to' the conclusion thati HasAvell's speci- 

 men was immature. Schimkewitsch therefore re-defined 

 the genua; a,s follows : — 



" Ce (jeni-e prvsente les vtaiidUndes (I.) triarticalees, jjas 

 " cheliformes, les extremifrs II. 10 articuh'es, les extremites 

 '^ III. 10 articulces, privfes dii. crocJiet et des epines plumi- 

 " formes, V article tarsale (8) des ex-iremitds IV. - VII. est 

 "muni d' epines hasales et de crochets secondaires font d Juit 

 " rudimentairts (au moins chez noire espcce)" 



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

 substance is- as follows : — 



" Body segments quite coalescent, lateral processes separate 

 "Proboscis large, thick, and moveable; cJielifori delicate, shaft 

 " tivo jointed, pincers delicate, occasionalhy rudimentary in 

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

 " longest, the remainder short. Ovigers of male slender, fourth 

 " joiid very long also the second and fifth, distal joints small, 

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