double one, being £ of the first. The caudal is almost truncated, the 

 central rays being but a little shorter than the rest, which are f of the 

 length of the head. The anal rays resemble the dorsal ; the spines 

 are strong, the second, the longest, about 2\ of the head. The anus is 

 situated a little in front of the first spine. The pectoral is nearly 

 triangular, the longest ray f- of the head. Each ventral is enclosed 

 by two elongated scales ; the spine is \ of the length of the head ; the 

 anterior ray is undivided, filamentous, its length equals that of the head ; 

 from the second, which slightly exceeds the spine, the rest gradually 

 decrease. The individual described was observed at Pinans; in August 

 1845. The fishermen declared it to be a young one, and of rare oc- 

 currence. A second, of somewhat larger size, was taken on the coast 

 of Malacca.
