but little longer than the upper, is f of the length of the head. The 

 two anterior dorsal rays are undivided. M. Valenciennes counts 17 

 rays in this fin, but his figure gives 16. Single young individuals occur 

 at Pinang at all seasons. 



Hemiramphus tridentifer, Cantor. 



Toda pendek of the Malays. 



Head above, back and upper part of the sides light bluish green, 

 minutely dotted with black, particularly towards the margin of the 

 scales ; along each side a shining silvery band, widening between the 

 dorsal and anal; narrower in front of the caudal; the band edged 

 above by a deep blue line, and longitudinally divided by the lateral 

 line ; rest of the sides and abdomen pale silvery white ; cheeks and 

 opercles shining silvery, the latter and the root of the lower jaw with 

 strong steel-blue reflections ; point of lower jaw greenish blue minutely 

 dotted with black, with a black marginal membrane, apex red sealing- 

 wax colour ; dorsal hyaline, margins of the rays minutely dotted with 

 black ; anterior half of caudal pale greenish buff, posterior half, upper

Total length : 7 inch. 



The length of the head from the apex of the intermaxillaries is 5^ 

 in the distance to the point of the lower caudal lobe. The length of 

 the lower jaw from the apex to where the teeth of both sides meet 

 varies from 6| to 6§ in the total length. Measured to the angle of 

 the mouth, the lower jaw is from 5£ to 5f in the total length. The 

 horizontal diameter of the eye is \ of the length of the head ; the 

 distance across the flattened forehead equals the diameter. The depth 

 at occiput equals \ of the length of the head. The teeth of both jaws 

 are placed on narrow bands ; in the centre of the lower jaw there is a 

 very minute interval between the teeth of both branches. The teeth 

 themselves are very minute, the internal series a little longer than the 

 rest. Examined through a lens the apex of each tooth appears com- 

 pressed, terminating in three minute points of which the central one is 

 a little longer than the two lateral. The intermaxillary forms a nearly
