The height of the body is a little more than one-half of the total* 

 length (without caudal) ; the width of the interorbital space, which 

 is very convex, equals that of the orbit ; the breadth of the infra- 

 orbital ring below the centre of the eye is rather less than one-half 

 of the greatest breadth of the praeorbital. Incisors moderately broad, 

 deeply notched. Body light-greenish, shining golden, with six 

 blackish cross-bands, which are as broad as the interspaces between 

 them: the first is indistinct and immediately before the origin of 

 the dorsal ; the second below the third to fifth spines ; the third 

 below the sixth to eighth ; the fourth from the eleventh and thir- 

 teenth to the anal spines ; the fifth from the middle of the soft dor- 

 sal towards the end of the anal ; the sixth across the middle of the 

 free portion of the tail.

The height of the body is one-half or somewhat more than one- 

 half of the total length (the caudal fin not included). The width of 

 the interorbital space equals that of the orbit (in immature speci- 

 mens), or is rather more in adult ones ; the breadth of the infraorbital 



* Mr. Gill mentions twelve anal raj s, whilst I can find oiilj ten in one of llie 

 typical specimens sent bv the Smithsonian Institution to the Museum.
