interocular space, when in ferox this diameter is two-thirds of 

 the same space. These two gigantic sorts have also numerous 

 other distinctive characters. B. gavialoides inhabits the West Coast 

 of Australia and ferox the North-Eastern one. I have seen a 

 fine specimen of the last in the Brisbane Museum, and I possess a 

 head of a specimen, also from Queensland. 



Hemirhamphus breviceps. 



Total length of the head contained three times and one-third 

 in the length of the fish without the caudal ; the beak is equal 

 to the distance between the anterior end of the mandible and 

 the posterior edge of the orbit ; the portion of the beak extend- 

 ing in front of the upper jaw is contained twelve times in the 

 length of the fish without the caudal ; the height of the body is 

 six times and two-thirds in the same measurement ; the back is 

 short, straight, and pointed at its extremity ; the diameter of the 

 eye is less than the interorbital space ; the caudal is forked, the 

 lower lobe rather longer than the other ; the dorsal is inserted 

 rather behind the anal ; ventrals inserted nearer to the anal than 

 to the end of the operculum ; pectorals rather longer than the 

 inferior jaw, and rather longer than half the total length of the 

 head ; body with a silvery lateral band surmounted by a blue- 

 black streak ; the baok brown ; dorsal 15, anal 15, pectorals 12, 

 lateral line 48 ; the end of beak is red. 



The specimens are about five inches long. They are from the 

 mouth of the Brisbane River, in salt water. This fish is called 

 Snub-gar at Brisbane ; it is generally found in great quantities 

 with H. rnelanochir, the latter bearing more particularly the name 

 of Gar-fish.

„ ocme, Richards, Ereb. Terr., p. 61, pi. 38. 



A specimen, absolutely similar to the one figured by Richardson, 

 has been sent to me by Mr. Staiger, as coming from the mouth 

 of the Brisbane River, and as being known in the Brisbane 

 market under the name of Sardine.
