Other differences may have significance too. The caudal peduncle 

 is longer and more slender in nuttingi; its length is 160 to 213 thou- 

 sandths of standard length, whereas in indicus, it ranges from 138 to 

 160. The posttemporal spine of nuttingi is shorter, 49 to 74 thou- 

 sandths, whereas in indicus it is 75 to 94 thousandths. The distance 

 from occiput to dorsal fin origin in nuttingi is 262 to 300 thousandths 

 of standard length, whereas in indicus it is 335 to 349.

Through the courtesy of Dr. Gilbert Whitley and J. W. Evans, 

 The Australian Museum, Sydney, I have examined 10 of the cotypes 

 of Polyipnus tridentifer McCulloch, Australian Museum Xo. E.3543, 

 one of which is 72 mm. standard length and is selected as the lectotype. 

 Although these cotypes differ slightly from specimens taken in the
