60 ACANTHOPTERTGII. 



horizontal limbs of the preopercle rather strongly serrated, its intramarginal crest entire. Teeth — villiform in 

 jaws, vomer, and palate. Fins — dorsal spines of moderate strength, the first very short, the second scarcely above 

 one-third of the len"-th of the third, which is about the same height as the fourth and fifth, being equal to half 

 the height of the body and two-tliirds of the raj's : soft portion of the fin with its upper edge cut square or slightly 

 emarginate. Pectoral as long as the head behind the middle of the eye : the ventral reaches the anal. Second 

 anal spine '2/.5 of the height of the body : caudal emarginate. Lateral-line — tubes well developed with a basal 

 enlargement which in some appears to be slightly arborescent. Colours — a broad brown band passes from the 

 snout throuD-h the eye and is continued to the end of the caudal fin : another from the upper edge of the eye to 

 above the fi-ee portion of the tail and continued to the base of the caudal fin. No median band from the eye 

 to the base of the dorsal fin. A badly developed basal band along the soft dorsal and another on the anal fin : 

 no black spot at the base of the caudal. 



Habitat. — Seas of India, to the Malay Archipelago and beyond.

Length of head 3|, of caudal 1/5, height of body 3^ to 3J in the total length. Eijes — diameter 1/3 of lengtli 

 of head, 3/4 of a diameter from end of snout , and the same apart. The width of the head equals two-thirds of its 

 length : jaws of about equal length. The maxilla reaches to below the hind edge of the orbit. Outer edge of 

 preopercle serrated along both limbs, its intramarginal crest entire. Edges of orbit smooth or sometimes a little 

 rouo-hened : shoulder serrated. Teeth — villitbrm in jaws, vomer, and palate. Fins — dorsal spines i-ather stout, 

 the first short, the second about half as high as the third which is the longest and equal to two-thirds of the height 

 of the body, and nearly as high as the rays : soft portion of the fin with its upper edge oblique. Pectoral as long 

 as the head behind the middle of the eye : the ventral docs not reach the anal: caudal emarginate. Lateral- 

 line — tubes distinct, with arborescent lateral projections. Colours — reddish-brown with four lateral longi- 

 tudinal bands, the third of which commencing at the snout passes through the eye to the centre of the base of 

 the caudal fin, along which it is sometimes continued to its termination, this band is usually edged below by a 

 narrow white one commencing at the pupil of the eye. The second and fourth bands may either end at the 

 upper and lower edges of the base of the caudal fin, or be continned along it m a converging direction forming 

 an arch near the end of the fin. A dark band runs along the first dorsal fin, and is continued as a black band 

 alone the middle or base of the second dorsal : the anal hq,s also a basal band. 



Habitat. — Seas of India to the Malay Archipelago and beyond.

Length of head 3j, of caudal 1/5, height of body 3-^- to 3i in the total length. Eijcs — diameter 2/5 of 

 length of head, 1/3 of a diameter from end of snout, and 1/2 a diameter apart. The head is very slightly longer 

 than hio-h : lower jaw rather the longer. The rise from the snont to the dorsal fin is not considerable. The maxilla 

 reaches to below the last fourth of the orbit. Vertical and horizontal limbs of preopercle serrated in their outer 

 edo-es. Shoulder bone crenulated or entire : edges of orbit smooth. Teeth — in viUiform bands in jaws, vomer, 

 and palate. Fins — dorsal spines weak, the first very short, the second short, and the third not so high as the 

 fourth, which equals the length ai the post-orbital portion of the head and nearly half the height of the body 

 below it. The pectoral reaches the anal, as does also the ventral : caudal slightly notched. Lateral-line — tubes 

 well developed but rather short and having a slight lateral enlargement, it forms a moderate curve becoming 

 straight below the end of the second dorsal. Colours — olive, with four or five naiTOW dark vertical bands from 

 the first dorsal and fii'st half of the second dorsal descending to the abdomen : a dark band, tliree scales wide, 

 over the free portion of the tail and only reaching to half a scale below the lateral-line. A black streak from 

 the lower edge of the eye to the angle of tlie preopercle ; numerous small brown spots on the head and also on 

 the body, more especially above the lateral-line. Fins grey, the anterior half of the first dorsal black : caudal 

 with a dark edge externally margined with white. 



Habitat. — Coast of Africa, seas of India and beyond, attaining to at least 3 inches in length.
