SERRATE-SPINBD CAT-FIgH. 



This fish resembles the preceding, but the head is less 

 mailed, and the spines of the dorsal and pectoral fins 

 are serrated on both sides. The cirri and fin-formula are 

 the same, but the upper cirri are not united by a mem- 

 brane to the head. The Burmese call both by the same 

 name.

LONG DORSAL-FINNED CAT-FISH. 



Another common cat-fish belongs to the section of 

 pimelodus, which has the adipose or second dorsal fin "of 

 such considerable length as almost to fill up the interval 

 between the first dorsal and the caudal, while it is very 

 low at both extremities." The first soft ray of the dorsal 

 fin is prolonged much beyond the others. The muzzle 

 is narrow, rounded, and has four short cirri on the lower 

 jaw and two on the upper, equalling the length of the 

 whole body.

FRESH-WATER CAT-FISH. 



A fresh-water cat-fish, a foot and a half long, of which 

 I have only brief notes, belongs to the 

 PimelodincB.

TOPSY-TURVEY FISH. 



This is an odious looking, small, fresh-water hsh, with 

 the general form of the river bull-head or miller's thumb, 

 but it appears to be a cat-fish of the tribe with a second 

 adipose dorsal fin. The ventral fins are placed far back 

 under the second dorsal, the head is mailed, with four 

 cirri on each jaw ; the two on the upper one are very 

 long, and two are very short. Its abdomen is enormous, 

 as large as that of a sea-porcupine, and the natives say it 

 always swims on its back, and hence they call it " the 

 back-going fish."
