of that species. C. allporti varies greatly with age both in the 

 depth of the body and height of the vertical fins, so that 

 Waite's figure represents the half-grown fish about 200 mm. 

 long, while that in the British Museum Catalogue is the figure 

 of an adult specimen. 



Though closely approaching the figure of C. platei in its 

 younger stages, C. aUporti nevertheless appears to be dis- 

 tinguished by its larger eye and higher vertical fins. The 

 other characters used by Ogilby to differentiate the variety 

 australis are dealt with below. 



My series includes specimens from less than five inches to 

 others over eleven inches long, and they show that the body 

 is much more slender in young individuals than in adults. 

 The greatest depth in the smallest specimen is 3 "21 in the 

 length from the snout to the hypural, and it regularly increases 

 with age until in the largest it is 2 '66 in the same. 



The height of the vertical fins also varies with age, as well 

 as individually. In the smallest specimen the longest anal 

 rays are 7*3 in the above length, while a large example has 

 them 5*04 in the same. In none are they so short as in the 

 figure of ('. pJatei w-hich shows them to be about 8*3 in that 

 length. 



The length of the head varies from 3'88 (young) to 4'6i 

 (adult) in the length from the snout to the hypural. In his 

 comparison of C. platei with C. p. australis, Ogilby's figures 

 show the head to be much smaller in the first-named. My 

 specimens, however, and a comparison of Steindachner's and 

 Waite's illustrations show tfiat this difference is not so great 

 as Is indicated. 



The eye of the young is larger than that of the adult, being 

 ^■7 as against 3 in the length of the head. The eye of C. 

 platei is proportionately smaller. The maxillary generally 

 extends to below the anterior margin of the pupil, but in one 

 specimen reaches almost to the middle of the eye. Ogilby's 

 counting of the fins and scales agrees with mine. 



Ogilbv has erected the genus Ajiogranjnut for ('. aUporti 

 regarding the strength of the vomerine teeth to be of generic 

 importance. I have large specimens agreeing in every other 

 way with the figure of C. aUporti in A\hich these are either 

 small or absent, while others of the australis form have them 

 well developed. AiU)o;i-a)U)}ia is therefore unnecessary. 



The "Endeavour" collection includes forty-three specimens, 

 most of which come from off Flinders Island, Bass Strait. 

 Six were preserved from elexen miles east of Parrenjoey 

 Head, New South Wales, 40 fathoms.
