Natal. 



Three specimens from Durban, 140 to 200 mm. in total 

 length. 



Gilchrist has examined a large example, 240 mm. long to 

 base of caudal fin ; in this the head is 3| in the length, and 

 there are 200 gill-rakers on the lower part of the anterior 

 arch.

Beaufort, Visb. ludo-Austral. Arch. ii. p. 66, fig. 24 (1913). 



Depth of body 2\ in the length, length of liead 3|. 

 Parietal ridges expanded and striated. Snout as long as 

 diameter of eye, which is 4 in length of head; maxillary 

 extending beyond middle of eye ; width of operculum | its 

 depth; 100 gill-rakers on lower part of anterior arch. 42 

 scales in a longitudinal, 15 in a transverse series; ventral 

 scutes 17 + 12. Dorsal 17-18. Anal 20-21. Pelvics below 

 middle of dorsal. Caudal about as long as head. A dark 

 humeral spot; dorsal and caudal dark-edged. 



Sumatra. 



Here described from Bleeker's type and only specimen, 

 which has the luad and body dee|.ier and the lower jaw longer 

 etc. than in A. kanagurta of this size (120 mm.) ; also the 

 first mid-dorsal post-cei)halic scale is a striated bony plate. 



Weber and Beaufort's figure is of a fish that agrees with 

 Bleeker's in the appearance of the iiead, but is more elongate 

 in form, the depth about 2f in the length.
