There is one adult and several young specimens of this species in the collection. 
They were netted in the neighbourhood of Singgora and Koh Yaw. The adult speci- 
men is from Singgora and is 143 mm. in total length including the length of the 
caudal fin. It agrees almost in every respect with Da3^'s description and figure of the
