end of this fin. Head contained four times in the length (with- 

 out caudal) ; eye twice and three-fourths in the head. The snout 

 is considerably shorter than the diameter of the eye ; the lower 

 jaw much longer than the other ; the maxillary extends to below 

 the first-third of the eye ; the cheeks and the two opercles are 

 finely striated ; the lower profile is rather more convex than the 

 upper one ; scales regularly arranged, rather firm ; they are 

 strongly striated with the margin finely crenulated ; dorsal of 

 nineteen rays, the end of this fin is at an equal distance from the 

 snout and the end of the tail. The caudal is deeply forked, of 

 sixteen long rays, with several shorter ones on each side, anal of 

 28 or 29 rays ; the ventrals are small ; the pectorals are nearly 

 twice as long, of sixteen rays. The general colour is bright and 

 silvery, with the back of a light purple ; the anterior part of the 

 head and fins are yellow; the operculum gilt. Length three inches." 



The species conies from Port Darwin. The most distinctive 

 character seems to be the number of the anal rays, I know no 

 Clupea with such a number. Nothing seems to be known of its 

 history.

The following is Dr. Grunther's description of the species : — 

 " <B. 6. D. 11. A. 9. S. lat. 35.' The height of the body is 

 one-sixth, or rather more than one sixth of the total length 

 (without caudal) the length of the head one-fourth. Snout rather 

 pointed, longer than the orbit, with the lower jaw slightly 

 projecting beyond the upper. Maxillary rather broad and 

 extending to the vertical from the front margins of the orbit. 

 Origin of the dorsal fin nearer to the end of the snout than to the 

 root of the caudal, ventrals inserted below the posterior third of 

 the dorsal fin. Back dark-coloured, sides and belly silvery, the 

 two colours sharply defined."
