374 ACANTHOPTERTGII. 



Lengtli of Head from 3| to 4, of caudal 4J to 4f , hfeigtt of body 2i to 2f in the total length. Hyes — 

 diameter 2f to 3 in length of head, 1/2 to 3/4 of a diameter from end of snont, and 1 apart. Preorbital and 

 lower edge of preopercle serrated. Maxilla reaches to below the fBont nostril. Profile very slightly concave 

 over orbits : snout obtuse. Fins — dorsal fin commences midway between end of snout and base of first ray, its 

 spines increasing in length to the last, which equals the postorbital length of the head, and is 2/3 as 

 high as the soft dorsal which is longest in its middle. Pectoral as long as the head. The ventral ray reaches 

 to the posterior extremity of the anal. Caudal slightly emarginate. Scales — ctenoid, about 19 rows between 

 first dorsal spine and the snout, they are but shghtly extended over the soft portion of the anal fins 

 and form a short sheath for the spines. Lateral-line — present. Golowrs — of a dull greenish, becoming 

 lighter along the abdomen : a dark, sometimes black, band from the eye along the side to the lower half of the 

 base of the caudal fin. A dark band in. the upper third of the dorsal fin, and another on the back 

 along the base of that fin : anal banded similarly to the dorsal, and likewise with a dark band along the bases 

 of its soft portion. Caudal sometimes with a black spot at its base, whilst its last third is rather dark, 

 occasionally with two or three transverse bands. 



Out of 20 specimens seven had 18, the remainder 17 dorsal spines : of the anal spines, five had 20 

 ten had 19, three had 18, and two had 17 ; those captured nearest the sea had, as a rule, the most spines. 



Habitat. — The Brahmapootra from Upper Assam at Debrooghur to the Hooghly at Calcutta. It is 

 termed " Ohwna hholisha at Goalpara," (H. B. MSS.). The TriehopodMS sota, H. B. Fishes of Ganges, p. 120, 

 appears to be a variety of this species, and is termed " BilJc songtak and kalak at Goalpara," (H. B. MSS.) Out 

 of 20 specimens the largest is 1"8 inches in length.

B. V, D. V, P. 10, V. 1, A. iz^s, C. 15, L. 1. 30, L. tr. 5-6/12. 



Length of head 4J, of caudal 4|, height of body 2| to 3J in the total length. Eyes — diameter 3^ in 

 length of head, 1 diameter from end of snout, and 1| apart. Preorbital denticulated. Preopercle very slightly 

 rounded at its angle, its lower limb rather strongly serrated: sub-opercle when serrated very ^lightly so. 

 Maxilla reaches to below the anterior nostril. Lips very thick and covered with papUlse (as in Labed). 

 TeeiA— present in the jaws. JYtos— dorsal spiaes increase in length to the last, which is 2/5 of that of the headj 

 soft dorsal pointed, its third to fifth rays being elongated, and from two to three times as long as the last spine! 

 Anal commences below the base of the pectoral, its soft portion elongated, but not to so great an extent as the 

 soft dorsal. Caudal wedge-shaped, the central rays being the longest. Scales — a few over the base 

 of the anterior anal spines, increasing in number posteriorly, whilst the soft portion of the fin is densely scaled : 

 fewer scales on soft dorsal. OoZowrs— greenish superiorly, becoming lighter beneath, from eight to ten 

 obliquely vertical dark bars on the sides. A light yellowish red band proceeds from the eye across the lower 

 jaw behmd the lip, whilst posteriorly it has a dark edge. Fins dark, outer edge of anal yellowish-red. 



Habitat.— Burma,, found in the Irrawaddi at Rangoon, and certainly as high as Mandalay. The specimen 

 figured (hfe-size) is from Rangoon.
