FAMILY, I— PERCID^. 65 



Length of head 1/3 to 3j, of caudal 1/5, height of body 1/3 of the total length. Eyes — diameter 2/7 to 

 3f in length of head, 3/4 of a diameter from end of snout, and 1 apart. Snout rather elevated. Lower jaw slightly 

 the longer : the maxilla reaches to below the hind edge of the orbit. Both limbs of preopercle serrated along 

 theu- outer edges, most slightly so on the vertical one : the other bones of the head and shoulder entire. Teeth — • 

 fine Ln jaws, vomer, and palate. Fins — dorsal spines of moderate strength, the second and thii'd of about the 

 same length, and equal to 2| in the height of the body, but not so high as the soft dorsal. Pectoral rather 

 longer than the ventral, which latter reaches two-thu-ds of the distance to the base of the anal fin : soft anal as 

 high as the soft dorsal : caudal lobed. Lateral-live — tubes distinct, some having a slightly arborescent base. 

 Colours — olive, with a darkish blotch on the side at the base of the caudal fin : blackish between the second and 

 third dorsal spine ; fins gi'ey. 



Habitat. — Seas of India and Malay Archipelago, attaining at least sis inches in length.

Length of head 2/7, of caudal 1/4, height of body 2/5 of the total length. Eyes — diameter 2 J to 2f in the 

 length of head, 1/2 to 2/3 of a diameter from the end of snout, and 3/4 of a diameter apart. Lower jaw the 

 longer : the maxilla reaches to below the middle of the orbit. The outer edges of both limbs of the preopercle 

 serrated, as is also the shoulder-bone, the other bones of the head entire. Teeth — villiform in the jaws, vomer, 

 and palate. Fins — second and third dorsal spines slightly higher than the foui-th, two-thirds the height of the 

 body and in length about equal to the raj's in the second dorsal fin. Pectoral as long as the head excluding the 

 snout. Ventrals reach the anal fin, the second spine of which last is two-fifths the height of the body, whilst 

 the rays are similar to those of the soft dorsal. Caudal forked, its three outer rays on either side rather spinate 

 and projecting. Lateral-line — tubes well-developed. Free poi-tion of the tail slightly longer than high at 

 its commencement. Colours — olive-brown, a dark zone round the body from in front of the first dorsal fin, and 

 passing to behind the ventral. Head spotted with black. A cloudy band below the second dorsal fin : free 

 portion of the tail with some black spots and blotches. First dorsal with some dark spots : ventral nearly black. 



Habitat. — Andamans, Malay Archipelago and beyond. The specimen figured (life-size) is from the 

 Andamans.

Length of head 2>\, of caudal 1/5, height of body Sj in the total length. Eyes — 3j diameters in length 

 of head, 3/4 of a diameter from end of snout, and 2/3 of a diameter apart. Dorsal profile rather concave over 

 the eyes. Upper jaw slightly the longer : the maxilla reaches to below the last third of the orbit. Both limbs 

 of the preopercle serrated along their outer edges, the other bones of the head and shoulder entire. Teeth — 

 villiform Fins — third dorsal spine is slightly the highest, and as long as the head behind the middle of the 

 eye. The ventral does not reach the anal. Caudal notched. Lateral-line — tubes well developed, having lateral 

 basal enlargements. Colours — greenish-brown with some dark spots on the head : a narrow blackish-brown 

 band passes from the head to the root of the caudal fin, where it end-s in a round black blotch : in its anterior 

 half it is margined on either side by a bluish-white streak, which gradually decreases in width : there is a 

 brownish blotch on the shoulder. The interspinous membrane between the second and third dorsal spines is 

 black. 



Habitat. — Nicobars, fi-om whence Dr. Stoliczka brought the specimen which is figured : it is found in 

 the Malay Ai-chipelago.*

Eyes — diameter 2/5 of the vertical height of the head. Form compressed : mouth small. Fins — pectoral reaching beyond 

 the second lateral band : the posterior dorsal and anal fins projecting similarly a.s far as the base of the tail fin. Colours — four vertical 

 black bands, a fifth at the base of tall, and the occipital region also of this colour. 



Habitat. — Andamans, about 1 inch in length. Unless some typographical error has occurred, this fish having three anal spines, 

 &c., cannot be referred to Ajiogon.
