 somewhat longer than second spine of anal, which is half as 

 long" as postorbital part of head. Dorsals, anal and caudal 

 scaly. Caudal very deeply forked, with elongate pointed lobes. 

 Pectorals pointed, straight, all of their rays simple, longer than 

 head by almost 2 eye-diameters. The two upper pectoral fila- 

 ments exceeding tip of tail by more than length of head and 

 body; third one reaching to end of tail, the fourth and fifth 

 reaching to or on anal; the sixth and seventh to tip of ventrals. 

 Ventrals equal to postorbital part of head. Distance between 

 origin of ventrals and of anal equal to length of head. Colour 

 of formol specimen yellowish, browner above. Fins yellowish. 

 Length 169 mm.
