STUDIES IX AUSTRALIAN SHARKS — WAITE. 229

Parascyllium collare, Ramsay and Ogilby, Proc. Linn. Soc. N. S. 

 Wales, (2), iii., 1888, p. 1310; 'Waite, Mem. Austr. Mus., 

 iv., pi. ii., fig. 2. 



The Collared Cat Shark reaches larger dimensions than the 

 fore named species, attaining the length of 825 mm. The egg- 

 case, which I believe to be of this species, is of considerable 

 capacity, measuring 73 mm. in length and 38 mm. in breadth, and 

 is light horn-colour in tint. The illustration shows its shape very 

 well, and rejaresents an example trawled on the " Thetis " Expedi- 

 tion in 1898, and obtained at a depth of 63-75 fathoms off Port 

 Kembla. Another living egg was trawled off Botany Bay in 79- 

 80 fathoms. The former specimen is attached to a Gorgonia 

 (Plu^nareJla peniia, Lamarck), and contained an embryo measuring 

 43 mm. in length. 



I take this opportunity of correcting an error in the explanation 

 of the plate, published in the Memoirs of this Museum and quoted 

 above. " Fig. 2. Male, three-fourths natural size," should read 

 "less than one-fourth natural size."
