The original description, based on four small specimens from Kago- 

 shima, the only specimens hitherto known, ma}^ be corrected and sup- 

 plemented by the following measurements of mature specimens. 

 Snout 2.9 to 3.1 in head, orbit equal to or shorter than snout ; inter- 

 orbital about 5 ; 4^ or 5 scales in a series from origin of second dorsal 

 to lateral line, not including the scale on the lateral line, 5 or 6 below 

 the second spine of the first dorsal ; pectorals with 14 or 15, instead of 

 17, rays; vertical diameter of orbit 1.1 in horizontal diameter; median 

 rostral ridge extending somewhat beyond vertical through anterior 

 margins of eye; length of second spine of first dorsal about 0.8 the 

 distance between its base and the anterior margin of orbit ; pectoral a 

 little more than half as long as head ; ventral filament usually reach- 

 ing well beyond origin of anal. Neither the length of the snout, nor 

 the number of spinous ridges on the scales distinguish C. jordani 

 from G. Jcishinouye^ these being the two differences held by Smith 

 and Pope to separate the two. 



The two young specimens from the Eastern Sea differ from those 

 taken in Kagoshima Gulf in the longer snout, more acutely angulated 

 preopercular ridge, shorter distance from ventral to isthmus, but the 

 material is too limited to form defuiite conclusions. 



Length of specimens 80 to 225 mm., 2G to TO mm. to anus.
