58 ? = 33-259 **3 
Length equal to three and three-quarter times that of the head, which is 
equal to the height of the body. The first dorsal commences above the 
posterior margin of the orbit, and is nearly twice as high as the second. The 
lateral line ceases before the end of the pectoral fins. A simple tentacle above 
the eye, and a pair of bifurcated ones over the snout. Colour (in spirits) 
uniform reddish. 
Bay of Islands and Cape Campbell.

In a letter to Dr. Hector, Dr. Giinther says that this fish does not belong 
to the genus Stichariwm, but should be referred to Clinus. I kept both it and 
Sticharium flavescens out of Clinus, on account of the small number of soft 
rays in the dorsal, but as Dr. Giinther says that they cannot be placed in the 
genus Sticharium, they will have to be called Clinus rubrus and C. flavescens, 
and will form a small group by themselves.

T. altivelis, Günther, HI., 303. 
A. 0 
Length about seven times the greatest height of the body, which is at the 
base of the ventral fins ; caudal nearly as long as the head, pointing obliquely 
upwards ; upper profile deeply concave, descending rapidly from the eye ; 
muzzle truncated ; cleft of the mouth vertical. Total length 20 inches. 
The above description is taken from a very bad specimen preserved in the 
Auckland Museum. 
57. Mugil perusii, Val. (Cat., p. 36.) Pl IX. 
In a letter to Dr. Hector, Dr. Giinther says that he thinks that our mullet 
is identical with M. cephalotus, C. & V. Tt appears to me to differ slightly 
from this species in having the head broader, in the length of the anterior 
dorsal spine being less than half the length of the head, and in its being ped 
rather nearer the snout than the root of the caudal. 
Judging from descriptions only, I should be inclined to think that our fish 
comes nearer to JM. ramelsbergii, but besides the head being broader, the 
posterior nostril is placed as in M. cephalotus. The second dorsal is also 
placed further back than in either of these species; the angle formed by the
