A male specimen procured at Tahiti by Lesson and Garnot 

 exhibits on the snout traces of eight cross-bars, and a trace of a 

 longitudinal streak near the lateral line passing over the head to 

 above the nostril. This specimen wants the tail. 



Dimensions of $ : — Head L50 inch, snout 1"02 inch, body

Dimensions of S : — Head 1*36 inch, snout 0'83 inch, body
