436 ANACANTHINI. 



ventral attached to the anal. Lateral-lines — two on the coloured side, separated at their greatest distance by 

 13 or 14 rows of scales: a single lateral-line on the blind side. jS'caZes— ctenoid on both sides. Cohurs — 

 stone colour, marbled with darker. 



Habitat. — Hooghly at Calcutta. 



In the Sittonng river in Burma is a very similar fish, D. lO.'i, V. 4, A. G8, C. l-l, L. 1. 100. Length 

 of head and height of body, each 5 in the total length. Eijes — small, contiguous, snout 2j in the length of head, 

 angle of mouth nearer snout than gill-opening. Height of head equals its length. Rostral hook reaches to 

 below the middle of the front eye. Fins — ventral not attached to anal. Lateral-lines — 2 on coloured side 

 divided by 14 rows of scales, 1 on blind side. Scales — ctenoid on both sides. Colours — brown, vertical fins 

 spotted with black and black edged.

B. vi, D. 101, V. 4, A. 76, C. 10, L. 1. 105. 



Length of head4j, height of body 4j jn the total length. Eyes — close together and small, 15 diameters in 

 the length of head, the upper slightly in advance of the lower. Head slightly longer than high, snout 3^ in length 

 of head. Rostral hook does not cover the symphysis. The angle of the mouth is 1 diameter behind the lower 

 eye, and much nearer the snout than the gill-opening. Two nostrils, one between the eyes, and a second tubular 

 one before the lower eye. Fins — longest dorsal rays 1/3 of height of body. Scales — ctenoid on both sides. 

 Lateral-lines — two on the coloured side divided by 15 or 16 rows of scales : a single lateral-luie on the blind 

 side. Colours — brown, with some vertical irregular bands of a darker colour and also blotches, fins dark with 

 light edges, each scale with a dark line along its centre. 



This species is closely allied to C. hrachyrliynclius, which however has rather a shorter head, higher body, 

 whilst the proportions of the head differ, and there are 17 or 18 rows of scales between the lateral-lines on the 

 coloured side. 



Ham. Buchanan's fish of which he has left a figure, " Acheirus kuhtr jjhjia" appears to be this species. It is 

 said to have no appreciable nostrils, but Buchanan observes, " I have not been able to observe any nostril, unless 

 it be concealed in a small membrane proceeding from the upper jaw, and below the under eye" (? the tubular 

 nostril) : Cantor and Giinther likewise observe, no conspicuous nostril, but the specimens of the former author 

 which are now in the British Museum, are dried skins, painted and smothered with varnish. As far as I can 

 judge it is this species which is not uncommon at Calcutta. 



Habitat — Hooghly at Calcutta, seas and estuaries of India. It attains about 6 inches iu length. The 

 specimen figured was from Calcutta.

Length of head 5, height of body 4 to 4f in the total length. Eyes — diameter about 13 in length of 

 head, 4^ diameters from end of snout and nearly 1 apart, the upper eye one half in advance of the lower. Head 

 1/6 longer than high. Angle of mouth below the hind edge of the lower orbit and midway between snout and 

 gill-opening. Rostral hook just covers symphysis of lower jaw. Two nostrils, a patent one between the eyes 

 and a tubular one before the lower eye. Fins — highest dorsal ray equals one-third of the height of the body. 

 Ventral not united to anal. Scales — ctenoid on both sides. Lateral-lines — two on the coloured side separated at 

 their greatest distance by 13 rows of scales. A single latei-al-line on the blind side. Colours — brownish, a 

 dark mark on operele. 



Habitat. — Burma to the Malay Archipelago.

 advance of the lower, 8 diameters in the length of head, and il from end of snout. Head 1/4 longer than high : 

 snout 3| times in the length of the head. The rostral hook covers the symphysis of the lower jaw, and 

 extends to below the front edge of the upper eye. Angle of the mouth 1 diameter behind the posterior edge of 

 the lower eye and slightly nearer the snout than the gill-opening. Two nostrils, one between the eyes, a 

 tubular one in front of the lower orbit. Fins — highest dorsal rays about 1/5 of the height of the body : a 

 single ventral attached to the anal. Scales — ctenoid on both sides. Lateral-lines — two on the coloured side,
