" The Blue Pointer" of the Sydney fishermen. 



Snout ending in a point, not long, its length from the front of 

 the upper jaw being about equal to the length of the cleft of 

 the mouth. The eyes are situated over the middle of the length 

 of the mouth, and the nostrils are in front of the lower margin 

 of the orbit, and nearer to the orbit than to the point of the 

 snout. The teeth in front of both jaws are long, rather 

 cylindrical, pointed, curved a little backwards and two rooted, 

 those on the sides are shorter, and of more compressed form. 

 Gill-openings very large, about equal. The first dorsal fin is 

 about midway between the vertical from the pectoral and ventral 

 fins ; it is triangular, nearly as high as long, and terminating 

 behind its lower extremity in a small pointed lobe. The pectoral 

 fins are rather small, and but slightly falciform, the posterior 

 margin being only slightly emarginate. The second dorsal fin 

 is extremely small, with a pointed lobe behind ; in size and form 

 the anal fin is exactly similar, but its commencement is opposite 

 the posterior point of the second dorsal. The caudal fin is 

 rather small, the lower lobe more than half the size and veiy 

 much of the form of the upper. On each side of the tail, 

 beginning opposite the termination of the anal fin, there is a 

 very prominent sharp edged cutaneous keel, and terminating at 

 the commencement of the caudal fin, its width at its middle 

 being near the one-fourth of its length. The skin is very finely 

 shagreened, almost smooth. The colour of the upper half of 

 the body is blue, of the lower white, the line of demarkation 

 between the two colours being distinctly marked and exactly in 

 the middle of the sides, the keel on the tail being exactly on 

 the line. 



Coasts of New South Wales. Length twelve feet. 



Genus Carciiaiiodon', Muller & Henle. 

 The first dorsal fin opposite to the space between the pectoral 

 and ventral, without spine, the second and the anal very small.
