GYMNOTHORAX MELEAGRIS (Shaw). 

 GYMNOTHORAX LAYSANUS (Steindachner). 



A specimen 390 millimeters long from a tide pool near Naha is 

 almost exactly like an example from Hawaii. The head and body 

 are closely covered with white spots which grow larger and fewer 

 posteriorly. These white spots are on a brownish background which 

 has numerous black spots about as large as the eye. 



GYMNOTHORAX PICTUS (Ahl). 



Finely clouded with brown and yellowish gray in life, the color soon 

 fading after death to pale brownish gray and white. 



GYMNOTHORAX UNDULATUS (Lac6pfcde). 

 GYMNOTHORAX PETELLI (Bleeker). 

 GYMNOTHORAX STELLATUS (Lac6p6de). 



Three specimens, one of which is like several collected at Samoa 

 by Doctor Jordan. The spots are about the size of the eye and are 

 scattered over the body, only the upper ones tending to arrange 

 themselves in a row. Another has the spots larger and not arranged 

 in rows. It is possible that both the Okinawa and Samoa specimens 

 are representatives of M. fimhriatus Bennett, figured and described 

 by Bleeker as G. isingleenoides? 



GYMNOTHORAX ALBIMARGINATUS (Temminck and Schlegel). 



In life, brownish gray, darker posteriorly, the fins growing more 

 dark toward the edges where they are narrowly bordered with dead 

 white; anterior portion of body finely reticulated with pale j^ellowish- 

 gray lines; snout and region about jaws tinged with salmon red; 

 iris reddish orange.
