296 ACANTHOPTERYGII. 



head, 3/4 of a diameter from end of snout, and 1/2 a diameter apart. Dorsal profile more convex than that of 

 the abdomen. Greatest width of head equals its length behind the middle of the eyes, whilst its height is 

 slightly more. Lower jaw the longer, cleft of mouth oblique, commencing opposite the upper third of the eye, 

 tlie maxilla reaches to below the middle of the orbit. Neither scales, rows of warts, or barbels on the head. 

 Teefh— in villiform rows, the outer of which is enlarged, and the last of the outer row in the lower jaw is 

 slightly recurved, but can scarcely be considered a canine.* Fins — dorsal spines flexible, having filamentous 

 terminations, the fin is as high as the body, and 1/3 higher than the second. Pectoral as long as the head. 

 Caudal rounded. Scales — strongly ctenoid. Colours — chestnut, with thi-ee rather wide transverse mterorbital 

 bands : between the eye and the dorsal fin are three more bands which cross the back, and four or five more 

 descend fi-om below the commencement of the second dorsal fin to 1/3 down the sides. Three bands descend 

 from the eye, another over the operclc and one in front of the pectoral fin. Both dorsal fins with brown spots. 



Eahitat. — Red Sea to the Andamans. I obtained two small specimens of this species at the Andamans, 

 the one figured is twice life-size.

Length of head 4^, of caudal 5^, height of body 6| in the total length. Eijes — diameter 3| in length 

 of head, 1/2 a diameter from end of snout, and 2/3 of a diameter apart. Greatest width of head equals half 

 its length : its height equals its length behind the eyes. Snout slightly depressed. Cleft of mouth rather 

 oblique, commencing opposite the lower edge of the eye, lower jaw the longer, the maxilla reaches to below the 

 liiud edge of the eye. Teeth — villiform, outer row enlarged, but without canines, two or three posterior canines 

 in the middle line above the symphysis of the lower jaw. Fins — dorsal spines with filamentous terminations, 

 and 2/3 as high as the body, an interspace of five scales between the bases of the two dorsal fins : last dorsal 

 rays two-thii-ds the height of the body, and reach half way to the base of the caudal. Pectoral as long as the 

 head behind the eyes. "Caudal wedge-shaped. Scales — ctenoid, extending forwards to opposite the hind edge 

 of the eyes, where there exists a large one (as in an Opldoceplialus') and 15 rows between it and the base of the 

 first dorsal fin, which are scarcely smaller than those on the body. Opercles scaled. Colours — light brown, 

 covered with fine black dots and spots on the scales. A dark band fi-om the eye across the opercles. A dark 

 spot on upper edge of base of pectoral. Dorsal and caudal spotted in rows. 



Habitat. — Madras, to If inches in length.

Length of head A}, of caudal 4f , height of body 4f in the total length. Eyes — diameter 3J in length 

 of head, 3/4 of a diameter from end of snout, and 1|- apart. Head broad and flattened superiorly, its greatest 

 width equalling its length behind the middle of the eyes, its height rather less. Cleft of mouth oblique, 

 commencing opposite the upper edge of the eye, the maxilla extends to below the middle of the eye. Teeth — 

 villiform, with the outer row enlarged, no canines. Fins — dorsal spines 2/3 the height of the body, a distance 

 equal to four scales between the bases of the two dorsal fins : last dorsal ray divided to its base, and nearly as 

 high as the body. Caudal rounded. Scales — ctenoid, 19 rows before the first dorsal fin, they suddenly become 

 larger below the second dorsal fin, where they are angular. Colours — dark brown, every scale on the body with 

 a dark purplish band down its centre. A dark spot above the axiUa. A black band across the base of the 

 pectoral. Caudal with eight angular bars of spots. 



Hahitat. — Madras, up to IJ inches in length.

Leng'th of head 4 J, of pectoral 4, of caudal 5 to 6, height of body 4i- to 5, of first dorsal up to 3, of second 

 dorsal and anal each 5' to 6 in the total length, i/^es— diameter from 1/3 to 2/7 of the length of head, 1/4 to 

 1/2 a diameter from the end of the snout, and li apart. Greatest width of head equals its length excluding 

 the snout, and its height is a little more. ]\louth almost horizontal, cleft commencing opposite the lower edge 

 of the eye : jaws of equal length. The maxilla reaches to below the middle or last third of the orbit. Teeth— 

 villiform, without canines, outer row in premaxillaries enlarged. Fins— tho second and third dorsal spines 

 elongated, filamentous: four rows of scales between the two dorsal fins, the bases of which are 1 diameter of 

 the orbit apart ; aljout 10 rows anterior to the base of the first dorsal fin. Caudal rounded. Scales — ctenoid, 

 eight rows between the origin of the second dorsal and anal fins : they exist on the opercles and are extended 

 on the head to between the eyes, on the cheeks they are rudimentary. Colours — olive, with very large deep 



* If this fish attains any size the probability is that a posterior lateral canine -n-ill be present in the lower jaw, judging from the 

 dentition in specimens of other species of the same size and what exists when they become large.
