NOTES ON SOME AUSTRALIAN SHARKS. 
J 85 
This problem has also been discassed by Fowler (Proe. Acad. Nat. Sci. 
Philad., 1908, p. 62), who has access to Blainville’s paper, but was unaware of 
Bose’s genotype designation. Fowler notes that Carcharhinus commersonii cannot 
be the type of Carcharhinus Blainville as it is a nomen nudum. The next of 
Blainville’s names, C. lamia (Baf.) is a synonym of Squalus carcharias Linne, and 
this, Fowler considered, would be the type “ which would upset Carcharodon of 
Smith, in which case I shall consider the Squalus vulpes Gmelin the type of 
Carcharhinus Blainville.” 
This would make Carcharhinus a synonym of Alopecias , the Thresher 
Shark. However, Bose’s selection of a genotype antedates Fowler’s, and the 
interpretation of Carcharhinus I have given above appears to be the correct 
one. 
Family Galeid^. 
The genera of Grey Sharks have been listed in Jordan’s “ Classification 
of Fishes,” 1923, p. 100, and only a few additions are to be noted, as follows : — 
Galeolamna Owen, Descr. Cat. Osteol. R. Coll. Surg. i, 1853, p. 96, no. 427. Haplotype, 
G. greyi, Owen, from South Australia. Id. Whitley, Rec. Austr. Mus. xviii, 
1932, p. 324. At present indeterminable. 
Hemitriakis Herre, Philippine Journ. Sci. xxiii, 1, 1923, p. 71. Orthotypo, H. leucoperip'era 
Herre, from Dumaguete, Philippines. 
Rhizoprionodon Whitley, Austr. Zool. v, 1929, p. 354. Orthotype, Carcharias ( Scoliodon ) 
crenidens Klunzinger. Substitute for Rhizoprion Ogilby, preocc. 
Negogaleus Whitley, Austr. Zool. vi, 1931, p. 334. Orthotype Hemigaleus microstoma , 
Bleeker. Substitute for Hemigaleus Bleeker, preocc. 
Notogaleus Whitley, Austr. Zool. vi, 1931, p. 310. Orthotype, Galeus australis Macleay. 
The genera of Galeidse may be conveniently divided into subfamilies, 
although Scylliogaleus deserves family rank. I would restrict Galeus and its 
allies to the Galeinse and separate other subfamilies as Galeocerdinse and 
Loxodontinse. Then the genera allied to the Carcharhinus of authors (not 
of Blainville, s. str.) would enter the subfamily Scoliodontinse, and it is to this 
group that the Queensland Grey Sharks belong. The identification of the 
genera is assisted by the keys given by Gill (Ann. Lyceum Nat. Hist. N. York 
vii, 1862, p. 399-400) and Ogilby (Mem. Qld. Mus. v, 1916, pp. 90-95). 
The “ Carcharhinus ” of Ogilby is no longer valid and requires 
subdivision, wherefore I propose Mapolamia, gen. nov. for C. melanopterus 
Quoy and Gaimard, and Gillisqualus gen. nov. for the Queensland Shark 
identified by Ogilby as Carcharhinus amblyrhynchos Bleeker. I have considered 
our Whaler Sharks as perhaps belonging to the genus Galeolamna of Owen, 
but more detailed research has convinced me that the status of Owen’s name 
is at present indeterminable, so I provide Galeolamnoides gen. nov. for 
Carcharias macrurus Bamsay and Ogilby, the Whaler Shark of New South 
Wales.
