Length of preoral portion of snout exceeding the width of the mouth hy 1/5, and equal to or slightly 

 above the distance between the eye and the first giU opening (it is still longer in the immature): the groove at 

 the angle of the mouth scarcely extends on to the upper jaw. Nostrils very much nearer mouth than the end 

 of snout. Teeth — Those in upper jaw rather oblique not swollen at their bases : those in the lower jaw very 

 oblique especially near the symphysis : none are serrated. Fins — The length of the base of the anal fin is 

 nearly or quite equal to its distance from the ventral, especially in the immature : the pectoral does not extend 

 so far as to below the origin of the dorsal, its posterior edge is nearly straight, its internal edge 1/3 of the 

 length of its outer. The caudal equals 3f to 1/4 of the total length, but is rather longer in adults than in the 

 immature. Colowr — Uniform gray superiorly, white beneath : the pectoral of a deep gray, having a white 

 outer edge, as have also the ventral and anal, posterior portion of caudal fin dark gray or nearly black. 



Habitat. — Seas of India to the Malay Archipelago and beyond. It attains at least two feet in length.

Length of preoral portion of snout 1/4 longer than the gape of the mouth, and equal to or slightly less 

 than the distance between the eye and the gill-opening : a groove at the angle of the mouth not, or but slightly 

 extending on to the upper jaw. Nostrils nearer to mouth than to the end of the snout. Teeth— ^e upper and 

 lower ones oblique without swollen bases and none serrated. Fins — The length of the base of the anal fin is 

 one haM, or less, than its distance from the ventral : the pectoral extends to at least below the origin of the 

 dorsal, its posterior edge is concave, and its interna;l edge about 2/5 the length of its outer : second dorsal 

 small, situated over the posterior half of the anal. Length of caudal fin about 3^ to 3|- in the total length. 

 Colowrs — Gray or bronze above, white below : fins gray, the posterior edge of pectoral, outer edges of ventral, 

 anal and posterior half of caudal, white : upper edge of caudal dark, as is also its posterior lobe. 



Habitat. — Red Sea, seas of India to the Malay Archipelago, and beyond : said on the Malabar Coast to 

 attain a considerable size, but the largest I obtained was twenty-nine inches in length. The example figured 

 (eleven inches long) was from Madras.

Ei-dah, Andamanese. 



Length of the preoral portion of the snout exceeding the width of the mouth by nearly 1/3, and equalling 

 the distance between the eye and the second gill-opening. A well marked groove at the angle of the mouth 

 extending on to both the upper jaw and along a portion of the mandible. Nostrils rather nearer the mouth 

 than to the end of the snout, the distance between the outer edges of the nostrils equal to the extent between 

 them and the end of the snout. Teeth — oblique and flat in both jaws without any serrature. Fins — the pectoral 

 extends to neatly beneath the middle of the first dorsal fin, it has its posterior edge rather concave, and its 

 inner edge equals 1/3 of the length of its outer : second dorsal rather small, with its posterior lobe produced, 

 it is situated over the last half of the anal. Length of the base of the anal equal to 2/5 of its distance from the 

 base of the ventral, caudal fin 2/7 of the total length. Colowrs — ^light brown superiorly becoming dull white 

 beneath. Fins gray and mostly with light outer edges. 



Habitat. — Seas of India to the Malay Archipelago and Japan. The example figured (a male, twenty-five 

 inches long) was from Malabar.
