'2.2.. ARAIAS Jordan and Starks. 



ylnmi.s Jordan and Stakks, Bull. U. S. Fish Com., XXII, 1904, p. 624 {ariommus). 



This genus is also a degenerate ally of Pseudopleuro}iectes. It is 



very close to Dexistes^ the only tangible character of importance being 



the naked e^^eball. The eyeballs are scaly above in Dexistes. The 



body is still more fragile than in Dexistes.^ and the scales are thinner.

 pi. VI, fig. 2 (Matsushima Bay). 



ITahitat.—Msitsashmvd Bay in deep water. 



Head, 3.8 in length; depth, 2.(); D. 71 to 74; A. 57 to 60; scale, 60; 

 upper eye, 2.8 in head; snout from upper eye, 4.33; maxillary, 3.75; 

 pectoral of eyed side, 1.87; of blind side, 2.75; caudal, 1.16. 



Rim of upper orbit veiy slightly protruding above rest of upper pro- 

 file; eyes separated by a narrow sharp ridge; anterior rim of lower eye 

 scarcel}' or veiy slightly anterior to that of upper, posterior rim ante- 

 rior to that of upper (to a greater degree in the type than in cotype); 

 mouth very small, considerably larger on blind side, the maxillary 

 reaching to just below anterior edge of orbit; teeth blunt, set in a 

 single, very irregular row, those of lower jaw projecting around on 

 eyed side farther than those of premaxillary; gillrakers short and tri- 

 angular, 3+7 on first arch; dorsal beginning above middle of upper 

 eye; pectoral of eyed side a little longer and not so bluntly rounded 

 as that of blind side; caudal doubly truncate, median rays the longer; 

 lateral line not arched, gradually curved up anteriorly; scales c3'cloid, 

 with occasionally a ctenoid scale with long irregular spinules (as the 

 spinules arc easily broken, leaving no trace, it appears probable that 

 the scales may have all been ctenoid); a few small scales running out 

 on fin rays. 



Color light pinkish brown, without definite markings; dorsal, anal, 

 and caudal with very faint wavy cross marks. 



Two specimens taken in Matsushima Ba}', at stations 3770 and 3773. 

 The type is the larger, and is 13 cm. in length. It is Cat. No. 51417, 

 U.S.N.M. The other from station 3773 is No. 8386, Stanford Uui- 

 versity.
