 xviii., 1903, p. 25. 



A single specimen, 130 mm. long, is preserved which is 

 figured. It cliff ers in a iew details from the original descrip- 

 tion, but I have compared it with a second example received 

 from Mr. Ogilby with which it is in every way identical. 



Loc. — Great Sandy Strait, Queensland, 9-11 fathoms. 



Two specimens are in the Australian Museum, one from 

 Port Curtis, and the other from Moreton Bay.

Proportions of two specimens 152 and 167 mm. long. 

 Head, from the premaxillary symphysis to the end of the 

 opercular lobe, 2.7-2.8 in the length to the hypural joint. 

 Height of body 1.1-1.2 in the head. Greatest length of orbit 

 '5.2-5.6 in the head, 1.2-1.4 in the interorbital width, and 

 2.4-2.8 in the snout. Narrowest interorbital Avidth, between 

 the orbital crests, 3.7-4.4 in the head, and 1.7-2.2 in the 

 snout. Snout, from the orbital rim to the premaxillary 

 symphysis, much longer than the post-orbital portion of the 

 head, and 1.8-2.1 in the head. Second dorsal spine 1.6-1.7, 

 ninth dorsal spine 1.3 in the head. Second dorsal ray shghtly 

 longer than the second spine, 1.5-1.6 in the head. Lower free 

 pectoral ray shghtly longer thon the one above it, 1.4 in the 

 head. 



D. iii, xiii-xiv/8-9 ; A. iill-12 ; P. 10+2 ; V. i/5 ; C. 12-14. 



Five specimens, 150-212 mm. long, exhibit some little 

 variation in the width of the interorbital space, it being 

 narrower in the smaller examples : the transverse interorbital 

 crest also varies somewhat, and is rather straighter than that 

 of P. didacfyluni, Pallas. In large specimens the cirrhose 

 appendages on the head and back, and on the dorsal and
