176 "ENDEAVOUR" SCIENTIFIC RESULTS. 



Colour. Whitish, with a bluish-black area encompas- 

 sing the throat, pectoral, and anterior abdominal region 

 and a similar area around the vent. The tip of the first 

 dorsal and a narrow margin of the second is black. 



Described and figured from the holotype, 255 mm. 

 long. Twenty-seven others, 118-253 mm. long, are 

 preserved. 



Localities. Great Australian Bight, south-east from 

 Eucla, 250-300 fathoms; 6th May, 1913. 



Great Australian Bight, south from Eucla, 350-450 

 fathoms; 14th May, 1913. 



Great Australian Bight, south-west from Eucla, 190-

The masterly papers quoted above, by Professor 

 Gilbert and Dr. Hubbs, include a complete list of known 

 Macruroid fishes and a comprehensive key to the species 

 of Ccelorhynchus and its subgenera. The following key 

 to the Australian and New Zealand species of the sub- 

 genus Paramacrurus is based upon an examination of 

 many specimens of four species, and one of 

 asperoceph alus. 



A. Teeth of both jaws in villiform bands. Subopercle produced 

 into an acute angle posteriorly; snout of variable length; 

 ridges of head usually distinct and armed with specialised 

 scales. Spinules on scales forming subparallel rows of equal 

 strength. subg. PAKAMACKUBUS. 



B. Snout, meas.ured obliquely, as long as or shorter than the 



eye. 

 C. Lower surface of head covered with asperities; scales 



on upper surface close-set. 



D. 4J scales between the lateral line and the tip of 

 the adpressed dorsal ; carinae of scales widely 

 spaced; head covered with rugose scales, some 

 of which are specialised and form strong ridges, 

 and are distinct on the opercles. australis. 



DD. !> scales between the lateral line and the tip of 

 the adpressed dorsal; carinae of scales close-set; 

 head covered with fine asperities, none of which 

 are markedly specialised and they do not form 

 strong ridges, while they are scarcely distinct 

 as scales on the opercles. asperocephalus.
