and anal yellowish white, minutely dotted with black, their marginal 

 part blackish ; ventrals white ; upper half of pectorals brownish, lower 

 yellowish white. Iris silvery, upper part bluish black.

Habit. — Sea of Pinang, Malayan Peninsula, Singapore, 

 Malabar. 



Total length : 6f inch. 



The teeth of the external series of the upper jaw are distant, but little 

 longer than those of the internal. Under the symphysis of the lower 

 jaw appear five pores. The anterior part of the air-vessel is dilated, 

 forming a rounded lateral process on each side of the vertebral 

 column. Immediately behind them the body of the vessel is con- 

 stricted, and the rest presents a broad lanceolate form, tapering 

 backwards into a sharp point. From each side proceed ten processes of 

 which the eight are branched, but the two posterior pairs, the longest, 

 are either simple or bipartite. The length of the air-vessel is about % 

 of the total. 



At Pinang single individuals occur at all seasons. The isinglass is 

 reputed good, but as the fish is of small size and not numerous, but 

 little is procurable.

Colours similar to those of J. dussumieri, but the body and fins so 

 closely dotted with black and brown as to impart a general pale brown- 

 ish appearance ; the marginal half of the caudal, anal and ventral fins 

 blackish. Iris silvery, upper half bluish black.

Total length : 6f inch. 



The teeth of the external series of the upper jaw are less distant, and 

 rather longer than in J. dussumieri. There are five pores under the 

 symphysis of the lower jaw. The form and length of the air-vessel is 

 that of J. dussumieri ; each side has ten branching processes, shorter, 

 however, and apparently placed at a greater distance from each other 

 than in the former species. The three posterior pairs are much longer
