SUPPLEMENT, 1888. 809 



fin somewhat concave. Fins — Dorsal spine situated over tlie hind quarter of the eye, 

 strong and about as long as the head, armed posteriorly with a double row of 

 recurved spines. Ventral spine movable with small curved spines posteriorly, second 

 dorsal and anal fins low : caudal rounded. Scales — small, each with 4 or_5 marginal spines, 

 while the male on either side of the tail has a long patch of short setiform spines some- 

 times absent from the female. Some short fleshy tentaches on the side of _ the body. 

 Colours — brown, spotted and marbled with black, a light band along the anterior half of 

 the body. Caudal fin with two dark vertical bands. 



Eahitat. —Ohtained by Mr. Haly in August, 1888, at Karativoe, Ceylon ; is found in the 

 Malay Archipelago, Chinese and Australian seas. 



Page 708. The Colombo Museum sustained a great loss during my absence last year : a small sun-fish, 

 Orthagoriscus, was brought for sale, but was unfortunately rejected (Haly, m the 

 Tainohanian, vol. ii, 1888, p. 165). This may have been the widely ranging 0. mola not 

 uncommon off the British coast, and which has been taken in New South Wales, &c., 

 and of which Klunzinger seems to have obtained a specimen in the Red Sea :_ or it may 

 be the form found at Amboina which was described and figured by Bleeker in 1873 as 

 0. oxyuropterus : or possibly a nondescript.

Length of head 2f to 3^ in the length of the body. Ei/es- diameter 3^ to 4 in the 

 leno-th of the head. Sometimes tentacles above the orbit and on the lower side of the 

 head, and on the back. Spines of varying lengths, from IG to 19 between the snout and 

 the dorsal fin : there are generally only two or three posterior to the dorsal fin. The roots 

 of these spines are long and strong, and have a distinct ridge along their basal portions. 

 Colours— \a.vge black yellow-edged blotches on the body of various shapes, and often 

 small black spots. The large black spots are in some cases badly defined. 



Habitat.— Iro-pica.1 portions of the Atlantic, Indian Ocean, and Archipelago, also the 

 Pacific. Found in the Gulf of Manaar by Sir Walter Elliot, and in Ceylon by Haly.

Snout short and obtuse : the distance between the mouth and the end of the snout being 

 less than that between the inner angles of the nostrils. Nostrils nearly midway between 

 the end of the snout and the mouth. Teeth— in the upper jaw of moderate size, the 

 anterior equilateral, rather longer than broad, those on the side oblique, with their posterior 

 ed^es concave, and both sides finely serrated : twenty-nine rows in the lower jaw, lanceolate, 

 their ed^es smooth, with a broad base, two-rooted, and some with an additional minute 

 lobe. i^i?(s— first dorsal commences opposite the axil of the pectoral: the second only 

 one-third of the size of the first, but larger than the anal, which is small : origin of anal 

 behind that of the second dorsal. Pectoral large, exceeding the distance between the first 

 o-ill-opening and the end of the snout, the length of its hmd margin only one-fourth ot 

 that of its outer. Caudal of moderate size, rather more than the distance between the two 

 dorsal fins. CoZomto— uniform, top of first dorsal may have been black. 



Habitat. -KvLrrachee, where an example 6 feet 8 inches long was captured. The specimen 

 is stuffed, and not in a good condition. It is very closely allied to G. elhoti,irom which 

 it differs in the smaller size of the second dorsal and anal fins, but is probably only a 

 variety.
