definite markings. The subparallel carinse of the scales 

 place this species in the subgenus Paramacrurus, but 

 in other characters it seems to resemble the species of 

 Oxymacrurus. 



All six specimens were taken together, but they are 

 unfortunately without data. It is nearly certain, how- 

 ever, that they were obtained eastward of Bass Strait.

An excellent series of seventeen specimens 

 225 (+) - 385 (+) mm. long, exhibits but little variation. 

 Five examples 260 ( + ) 385 (+) mm. long have the 

 following characters : 



D.ii/10-11; P.16-19; V.8. The head (43-74 mm.) is 

 5-0-6-3 in the total length, but the tips of the tails are 

 missing in all. Depth (36-63) 1-1-1-2 in the head. Orbit 

 (14-26) 2-8-3-0 in the head, and 1-1-1-2 in its postorbital 

 portion (17-30). Bony interorbital width (12-24) 1-0-1-1 

 in the orbit. 



Identity. The characters relied upon to distinguish 

 the four known species of Malacoceplialus are largely 

 proportional measurements of a few individuals of each. 

 They are far from satisfactory, and I find nothing to 

 distinguish the Australian specimens from M. Ice-vis as 

 described and figured by Holt and Calderwood (loc. cit.}. 



Range. Though originally described from Madeira, 

 M. hrvis has since been taken in the North Sea, north 

 and south Atlantic Ocean, and the Indian Ocean. It is 

 therefore not surprising to find it in southern Australian 

 waters, because several other deep-sea fishes with a 

 similar range have been obtained by the "Endeavour" 

 in the Great Australian Bight. 



Locality. Great Australian Bight, south from Eucla, 

 350450 fathoms; 14th May, 1913.
