ICHTHYOLOGY 
longated ; the ventrals large, extending t to the end of the 
pectorals j the head, from the muzzle to the end of the 
opercale, is contained four and a quarter times in the total 
length ; the caudal three and one-fifth in the same length. 
The head is a little broader than the body, the breadth of the 
latter is contained six and a half times in the total length. The 
general colour (in the liquor) is of a greyish purple. On the 
head, traces of darker spots. The first dorsal has an ocellated 
white spot and several irregular ones ; these spots are bordered 
off with black lines, and they are covered with small brown lines ; 
the second dorsal has two series of transversal white spots 
extending on their membranous part, one towards the middle, 
and the other near the superior margin; they are also bordered 
with black and covered with narrow concentric brown lines ; 
between them there are other small rounded similar spots, and 
towards the base of the fin are seen some very indistinct lines ; 
the caudal is covered with little white irregular but longi- 
tudinal lines, and also with small black spots ; the anal is 
dark towards its margin and covered with narrow oblique 
white lines ; the ventrals have a yellow tinge and become 
darker towards their extremity ; the pectorals are of a lighter 
brown, and have some very faint brown spots on their 
superior part ; on the orbits of the t eyes, and on the sides of the 
body appear numerous transverse lines ; the lower part of the 
body is of a whitish colour ; the operculum terminates by a 
sort of long, flat, arched spine, bifurcated at its extremity. 
Cape Schanck— total length, four inches. 
I have also seen several specimens from Hobson's Bay • 
this species seems to be nearly allied to Cat. ocellatus, Pallas 
(Spic, vol. viii., pi. 51, and Encyclop. Method, p. 43, pi. 27, 
fig. 95.) 
Nota. — I have a specimen of Callyonimus from Hobson's 
Bay, in which the tins, and particularly the first dorsal, 
.are lower, and the ocellated spots of the latter are less 
marked ; it is only about three inches long. 1 think it is the 
female of this sort, and in that case none of the caudal 
rays would be produced in either sex.
