29. PARALICHTHYS OLIVACEUS (Schlegel). 



Two small specimens. 



Family SOLEID^. 



30. ARELISCUS RHOMALEUS Jordan and Starks, new species. 



Head, 4| in leng-th to base of caudal; depth, 4. Eye, 19 in head, 7 in 

 snout; snout, 2f. Dorsal, 124; anal, 96; scales, 148 from vertically 

 opposite upper end of gill opening-; 17 anterior to this point and 

 transverse row of pores. 



Interorbital space wide, flat, and scaled; its width 1^ times diameter 

 of upper eye. Upper eye from one-fourth lo one-half of its diameter 

 in advance of lower. Hook of upper jaw moderate, not nearly reach- 

 ing to opposite front of eyes. Maxillar}- extending half a diameter of 

 eye past posterior margin of lower eye. Nostrils as usual, the upper 

 one between front of e^^es, the lower one in a tube at edge of mouth. 





Fig. 5.— Arehscus rhomaleus. 



Scales strongly ctenoid on e^^ed side of head and body, cycloid on 

 reverse side. The three lateral lines on body and the connecting 

 branches on head very conspicuous. At middle of body the lines are 

 separated by 24 rows of scales counting obliquely. No lateral line on 

 blind side of body; a light line suggests one, but no pores are present. 



Body and tins uniform dark brown on eyed side, no color on tins on 

 blind side. 



This species is close to Arellscus ahhreviatus (Gray), but the scales 

 are finer. The latter, according to Giinther, has 120 scales in a lateral 

 series and the lateral lines are separated by 19 series of scales. Are- 

 liscus trigrammus (Giinther) has a longer dorsal, larger eyes, and nar- 

 rower interorbital space. 



Here described from the t^^pe, 38 cm. in length. Cat. No. 55635, 

 tJ.S.N.M. Several cotvpes are numbered 9883, Stanford University.
