List of stations. 



1 The type station was wrongly located in the original description; it is off the east, not the west, coast 

 of Borneo. 



In form, in the breadth and softness of the head, in the size of the 

 eye, in the development of the sensory canal system, and in the 

 strength of the opercular spines, this species occupies a position inter- 

 mediate between the species of the B. cottokles type, on the one 

 hand, and those species with comparatively firm heads and large 

 eyes on the other hand. 



Our measurement of the interorbital differs a little from that 

 given in the original description. As we measure, the orbit is con-
