the scales liavLng minute black dots, forming horizontal lines, wliicli are most distinct along the back : the 

 scales in the second and third rows having a pearly white spot at the base of each. Upper half of the first 

 dorsal black : second dorsal and caudal with black edges. A moderately wide band along the middle of the 

 second dorsal, which appears to be sometimes spotted with blue. 



Habitat.— Madi'SiS to 3| inches in length, as far as the Malay Arcliipelago.

Length of head 1/3, of caudal 2/9, height of body 2/7 to 1/4 of the total length. jBi^es— diameter 1/3 to 2/7 

 of the leno-th of head, 1'2 to 1/3 of a diameter from end of snout, and also apart. Jaws of about equal length : 

 the maxilla reaches to slightly behind the posterior edge of the orbit. Edges of preopercle, also of the other 

 bones of the head and shoulder entire. Teeth — villiform in the jaws, vomer, and palate. Fins — first dorsal spine 

 very short, the third and fourth the highest, equal to the length of the postorbital portion of the head, and 

 three-fourths as high as the rayed fin. Pectoral as long as the postorbital portion of the head. Ventral 

 reaches two-thirds of the way to the anal, the second spine of which last tin is equal to two-fifths of the height 

 of the body. Caudal rounded or cut rather square. Lateral-line — either ceases under the middle of the soft 

 dorsal fin, or reappears lower down going direct to the centre of the base of the caudal fin : tubes distinct, 

 generally with a basal swelling. Colours — body and head spotted and marbled all over with brown. A circular 

 black spot on the opercle enclosed by a narrow white ring, which is present even in the fry. 



Bleeker observes that he formerly considered tliis species as identical with A. punctulatus, Riippell^ 

 A. auritus, C. V. the interrupted lateral line and the distribution of colours being much the same. He now 

 divides them, as Riippell's fish appears to have a higher body, 4 longitudinal yellow bands over the preopercle, and 

 only 20 rows of scales. 



Having examined specimens taken in the Red Sea and elsewhere, I have not found less than 23 scales 

 along the lateral-line, and in two specimens from Zanzibar the lateral-line is continuous.

The foregoing measurements lead me to doubt the specific difference between A. auritus from the Red 

 Sea, and my species from the Andamans which=yl. polystigma, Bleeker. 



Habitat. — Red Sea, East coast of Africa, seas of India to the Malay Archipelago and beyond.

Length of head 3j, of caudal 2/11, height of body 2/7 in the total length. .Byes— diameter 2/7 of lengtli 

 of head, 1/2 a diameter from end of snout, and 1 apart. Lower jaw very slightly the longer : the maxilla reaches 

 to below the posterior edge of the orbit.* Vertical limb of preopercle entire, or very finely serrated on its lower 

 half and outer edge, more distinctly i-ound its angle and on the outer edge of its horizontal limb, there may also 

 be a few serrations likewise along its inner angle : lower edge of orbit roughened : shoulder entire. Teeth — tine 

 in jaws, vomer, and palate. Fins — spinous much lower than the soft dorsal, its third, fourth and fifth spines the 

 hio-hest, and equal to two-fifths of that of the body : the second dorsal three-foui-ths as high as the body, its 

 upper edge and also that of the anal being rounded. Pectoral as long as the ventral, wliich does not reach the 

 anal : caudal rounded. Pseudobranchice — present. Free portion of tail rather longer than high at its base. 

 Lateral-line — at tirst arborescent, but posteriorly with a lateral plate-like prolongation on either side of the base 

 of each tube. Colours — golden, upper surface of head and jaws, also upper portion of oi^ercle with black spots : 



* In examining some immature specimens of this fish in the Britisb Museum, I found th.at .at l^'g inches in length, the 

 diameter of the eye was 2/5 of the length of tlie head, and the maxilla reached to nc.irly below its centre. At :i inches in length, the 

 diameter of the eye was l/:5 of the length of the head, and the maxilla reached to below the last third of the orbit.
