PRISTIOPHOEIDiE. 



" The rostral cartilage is produced into an 

 exceedingly long flat laminae, armed along each edge 

 with a series of teeth (saw)." 



PKISTIPHOETTS. 



Formed by Muller and Henle. 



PRISTIPHOBTJS CIBBATTJS. 



Pristis Cirratus, Latham, Trans. Lin. Soc, vol. ii., 1794, 



p. 281, pi. 26. 

 , Blocli, Scfai., pi. 70 (the head 



only). 



The saw, from its extremity to the anterior edge of the orbit, is 

 contained four and one-third times in the total length of the 

 fish ; the distance between the tentacles and nostrils equals that 

 between the nostrils and the fourth gill-opening ; the fins are 

 entirely covered with very minute scales, as is also the body. 



The colour is entirely grey. 



I have not seen this sort from Victoria, but I have received it 

 from Hobart Town, through the kindness of Mr. Lavington 

 Eoop. 



PBISTIPHOETTS NTTDIPEOTS. 



Pristiphorus Nudipinnis, Ounther, Catal., vol. viii., p. 42. 

 (Saw Fis1u~) 



This sort is very nearly allied to the precedent, but has been 

 most properly separated from it by Dr. Gunther. The saw is 

 not so long, being contained four and. three- quarter times in the 

 total length ; this saw is also broader at its base ; the distance 

 between the tentacle and nostril is considerably less than that 

 between the nostril and the first gill-opening. A portion of the 

 pectorals and of the dorsal is denudated of scales, but the extent 

 of this portion is subject to considerable variation. 



The colour is of a light grey, with the pectorals and ventrals 

 reddish. 



Common in Hobson's Bay.
