CHECK-LIST OF CEPHALOCHOBDATES, ^-c.—OGILBY. 83 



Figures : — Maclay & Macleay, ibid., pi. 25 ; Waite, Mem. Austr. Mus., iv, pi. 1 



{dentition). 



Dimensions : — To fully 110 cm. 



Range : — Coast of South Queensland. Tweed Heads {Ogilby). This is a more 

 northern species than the preceding and I was not, therefore, much astonished at 

 learning of the capture of a specimen north of the Tweed, and the less so that the 

 " Endeavour" trawled a fine example off Byron Bay. Further proof of its more 

 northern range, as compared with H. 'phillipi, may be found in Waite's report that 

 while the "Thetis" trawled that species at 14 stations between Shoalhaven Bight and 

 Cape Hawke, not a single specimen of G. galeatus was taken.^'

^* Tf Houttuyn's "Nat. Hist., 1764" be binomial, as is his 1782 work, these should respec- 

 tively be Torpedinoidei and Torpedinidce. 



^* The name is derived from the Greek TrpiaTi?, gen. Trpto-Tcw?, "a large kind of fish," 

 and the family name should, therefore, by the laws of nomenclature be as above ; see
