 Pools at Naha. 



EVIOTA ABAX (Jordan and Snyder). 



A few examples of this species do not appear to differ in any way 

 from others taken at Tanegashima and Misaki. The first two dorsal 

 rays are sometimes lengthened to form a filament. 



EVIOTA ZONURA Jordan and Seale. 



Numerous specimens of tliis form agree in every particular except 

 color with examples from Samoa. The color is a httle more intense 

 in the Okinawa specimens, the pigment dots on the head tending to 

 cluster in blotches, the scales usually being stippled near their edges, 

 and the paired fins somewhat dusky. The lateral series of scales num- 

 ber 22 or 23 in individuals from both Samoa and Okinawa — not 28. 

 Occasionally specimens have the first and second dorsal rays greatly 

 elongate and closely united by membrane, thus forming a flat fila- 

 ment. The teeth of the upper jaw are in two series, an outer row of 

 large canines and an inner band of small teeth. On the lower jaw are 

 an outer and an inner row of canines, between which is a band of 

 smaller teeth. It is usual to find one or two enlarged canines on each 

 side of both jaws. The teeth of E. ephiphanes, the t}-pe of the genus, 

 are similar.
