 depth of caudal peduncle 24^ to 3 ; pectoral 1% to 1% ; ventral 31^ to 

 3^ ; caudal 2%o to 3V^ in rest of body.

 Snout end and mandible dusted with dull dusky. Dorsal and caudal

East Africa, Delagoa Bay, Natal, Madagascar, India, Siam, East 

 Indies, Philippines, Queensland. It seems hardly doubtful but that 

 Pellona natalensis Gilchrist and Thompson is the present species. 

 My South African materials all seem to agree, likewise the Mada- 

 gascar example I recorded as Ilisha ditchela. According to Day that 

 species has abdominal serrae 23 + 10, while the Madagascar example 

 shows but 19 + 8. The species is, however, closely allied to Ilisha 

 hoevenii in the structure of its maxillary.
