NOTES ON SOME AUSTRALIAN SHARKS. 
191 
First dorsal originating over posterior part of pectoral base. Pectorals 
rather short, and with rounded extremities, but they have evidently been 
damaged and the tips regenerated. In any case, they would not be nearly as 
long as the head and their length is about 1J times their width. Length of 
anterior margin of pectoral, from base to tip, less than distance between eye 
and last gill -opening ; the adpressed fin does not quite reach the vertical of 
posterior angle of dorsal base (Ogilby says it reaches to below anterior third 
of first dorsal, but this is incorrect). Ventrals below interdorsal space. Second 
dorsal and anal almost opposite, the anal origin being almost imperceptibly 
posterior ; the fins subequal. Upper caudal lobe notched. 
Coloration in formalin, dull plumbeous, darkest on dorsal surface and 
on fins. 
Described and figured from Ogilby ’s specimen of “ Carcharhinus 
avnblyrhynchos , 5 ’ the holotype of my new species, a female nearly two feet long. 
Locality . — Cape Bowling Green, Queensland. Qld. Mus. Regd. No. I. 2003. 
It differs notably from the descriptions of Bleeker’s type in having much 
shorter pectorals and in having the first dorsal base longer than the height 
of that fin, and in having the snout acutely pointed rather than almost semi- 
circular. The proportions and coloration are different and the new species 
has tricarinate dermal denticles. There are minor discrepancies as well which 
induce me to separate the present form as a new species. 
GALEOLAMNOIDES, gen. nov. 
Orthotype, Carcharias macrurus Ramsay and Ogilby = Galeolamnoides 
macrurus. 
Upper teeth triangular, very oblique laterally, and serrated on both 
edges ; their outer edges are more or less notched, the angle being very much 
greater in those on the sides than near the symphysis. Lower teeth narrow, 
erect, and more or less obscurely serrated. Snout rather long and rounded. 
Spiracles obsolete. 
Dorsal fin entirely behind vertical of pectoral base. A detailed 
description and figure of the typical form has been given by McCulloch (Proc. 
Linn. Soc. N. S. Wales, xlvi, 4, 1921, p. 457, pi. xxxvii, figs. 1-4).
