E. Tcobensis differs considerably from E. grandisquama in the fol- 

 lowing characters: 





E. kobensis. 



E. grandisquama. 



Scales 



54 to 56, firm and strongly ctenoid; 



fins more scaly. 

 Filamentous, much longer than the 



second ray, twice length of head. 



Broadly elliptical 



35 to 36, caducous, weakly ctenoid. 



Not filamentous, about equal to 

 second, only slightly longer than 

 head. 



Ovate. 



Weakly developed, not entering 

 into profile of head. 



A single dull wide spine at anterior 

 end of lower ridge, and a few tu- 

 bercles posterior to this. 



A single tubercular spine at ante- 

 rior end of upper ridge. 



Lighter brown, caudal with 2 dark 

 spots, 1 on upper and 1 on lower 

 edge of fin; snout without dark 

 spots.

Color 



Strongly developed, entering into 

 profile of head. 



1 main spine, sharp, on median an- 

 terior margin, and a few elevations 

 of lower ridge. 



A sharp spine directed forward at 

 anterior end of upper ridge, 1 to 3 

 smaller spines on anterior ridge. 



Darker brown, without caudal spots, 

 snout of male spotted. 





The two adult males obtained have a roughly triangular dark area, 

 which covers most of the blind side behind the pectorals. 



The fifth specimen in the table shows that young males are similar 

 to the females in measurements. This specimen also lacks the color 

 on the blind side. 



Dr. G. H. Gilbert, while in charge of the scientific work of the 

 Japanese cruise of the Albatross, made these color notes on the first 

 specimen in the following table: 



Anterior half of interorbital space, in advance of a nearly vertical ridge between 

 the eyes, marked with numerous fine yellow spots in nearly vertical series, and 

 between these, parallel series of slightly larger blue spots. Similar spotting on anterior 

 portion of dorsal fin. A few orange spots on ventral of colored side, and two larger 

 orange spots on mandibular membrane of colored side. Greater part of blind side 

 dark blue.
