Remarks. — Judging by its relative abtmdance in tdie 

 collection of the Australian Museum, and of the Zoological 

 Department of the University of Sydney, this must be 

 the most common pyonogonid found in Poi-t Jackson. 



Affinif'iPs. — I find on consulting my notes that Loman 

 (1908, p. 38) suggests that this species isi closely allied to 

 N. giraffa from the Strait of Macassar and possibly also 

 to the insutticiently described N. longiceps (Grube, 1869) 

 from the China Sea.

Specimens. — Australian Museum Collection, G5199, 

 marked "type, PoTt Stephens" ; Australian Museum Col- 

 lection, G5200, marked "Type 9, Port Stephens." These 

 are two microscope slides. The former of the specimens 

 is a male, the latter, in spite of its being marked female, 

 is also a male. 



Description. — Body is fairly robust with all segments 

 distinctly separated. The crurigers are separated from 

 one another by less than their own diameter. 



Ceplialon is expanded with a prominent anterior mar- 

 gin projecting over the proboscis. Above the base of each 

 chelophore on the cephalon is a prominent tubercle with 

 two spines. The neck is well developed and short but 

 fairly wide. 



Ocular tubercle is situated just behind the neck, im- 

 mediately anterior to tlie level of the first pair of crurigers. 

 There are four well developed eyes. Tlie shape of the 

 oculai" tubercle is not determinable with accuracy, but it 

 appears to be low and rounded. 



Abdomen is short and rounded. 



Proboscis is short and cylindrical directed obliquely 

 downwards. It is somewhat constricted in the middle, 

 obtusely conical in front with a wreath of very delicate 

 bristles round the mouth. The proboscis is inserted into
