Length of head 4, of caudal fin 4i, height of body 3i in the total length. Eyes — 

 diameter one-third of the length of the head, 2/3 of a diameter from the end of the snout, 

 and the same distance apart. Lower jaw the longer. Cleft of mouth very oblique : the 

 maxilla reaches to beneath the front edge of the orbit. Preorbital with seven strong 

 teeth along its lower edge : a spine at the posterior-superior angle of the orbit. Vertical 

 limb of preopercle entire : its horizontal double edge serrated the lower most coarsely so. 

 Sub- and inter-opercles entire. Teeth — villiform in jaws, vomer, and palate, a small central 

 baud at the root of the tongue. Fins — second spine of the dorsal longest and equal to 4^ 

 in the total length, and 2/3 the height of the body below it. Ventrals reach the vent: 

 pectoral reaches to above the third anal spine, which latter is longer and weaker than the 

 second, but half shorter than the third dorsal spine. Scales — two to three rows along the 

 cheeks. Lateral-line — curves to near the middle of the soft dorsal, when it becomes straight, 

 it is uninterrupted. Colours — silvery, with a burnished lateral band. Interspinous 

 membrane between the second and third dorsal spines spotted with black. 



Habitat. — Sea at ISIadras, from which Mr. Thurston has sent me one specimen 4 inches 

 long, to the Malay Archipelago and Cook's Islands.

Length of head 3^, of caudal fin 5^, height of body 2* in the total length. Eyes — 

 diameter 3|- in the length of the head, f of a diameter from the end of the snout, and 1 

 apart. A very slight rise from the snout to the base of the dorsal fin. Snout a little 

 elevated : xipper jaw slightly the longer, and extending posteriorly to below the last third 

 of the orbit. Both limbs of the preopercle serrated, the vertical one finely and evenly, the 

 angle rather coarsely and the lower limb more irregularly: shoulder scale serrated. Teeth 

 — villiform ones in jaws, also present on vomer and palate. Fins — Dorsal spines strong, 

 the two first short, the third slightly the longest, and equal in length to the head behind 

 the middle of the eyes, and nearly half the height of the body below it : the rays of the 

 second dorsal as long as the longest dorsal spine and one-fourth longer than those of the 

 anal fin. Pectoral reaches to above the anal spines, and the ventral nearly as far. Caudal 

 somewhat square at its extremity. Lateral-line very slightly curved, becoming straight 

 on the free portion of the tail : its tubes simple with a basal expansion on each side. 

 Colours— greyish, darkest along the back and a dark band behind the base of the second 

 dorsal fin : an oval black spot nearly as large as the orbit and surrounded by a narrow 

 yellow ring exists below the lateral line and under the first dorsal fin. Vertical fins black, 

 caudal yellowish. 



Habitat.— lladrsLS, from which Museum I have been lent by Mr. Thurston, a specimen 

 3 inches long.

Apogon maximus, Boulenger, P. Z. S. 1887, p. 655. 



Some very fine examples, in which the black spots are unusually large, were received 

 from the Persian Gulf and thus named. The third and fourth dorsal spines are only half 

 the length of the head, the eye is naturally smaller than in recorded specimens, and the 

 maxilla extends to below the middle of the eye. These fish reach to about 10 inches 

 in length.
