96 NOTES ON GALEOCERDO RAYNERI, 



above the mouth, shorter and wider below, extending round the 

 angle of the mouth ; a deep pit at the root of the tail above and 

 below, a narrow erect ridge between the dorsals. 



The color is, above bluish-grey, below silvery- white. Teeth 

 in eleven rows — the central ones above and below very small — 

 oblique, with a large and strongly serrated, lateral, external lobe 

 pointing outwards ; the base broad, in form somewhat triangular. 

 The spiracle is conspicuous, it is a narrow, curved slit, three- 

 quarters of an inch long, situated a little below and behind the 

 eye. The claspers are long, round, comparatively short for the 

 size of the fish, with an oblique, curved, linear groove. The 

 snout is as broad as long, the nostrils situated near the mouth. 



Port Jackson and the waters of the adjacent Coast abound in 

 Sharks of a large size and of great beauty. 



It may be interesting to note some of the species with which 

 we are blessed, I therefore give the following list of those 

 recently obtained in Port Jackson alone, with the lengths of some 

 of the largest : 



Carcharias macklotii . . . . Length 3ft. 

 ,, gangeticus 

 ,, Irachyurus

Galeocerdo rayneri 



Zygmna leuwinii * . . 



Lamna glauca

* W. H. Haswell, M.A., the accomplished Curator of the Brisbane Museum 

 informs me that he has recently secured a specimen of this species 10 

 feet in length. 



t Baron N. de M.-Maclay makes of this a new species under the name of 0. 

 cinerea.
