HIPPOGLOSSOIDES PROPINQUUS, new species. 

 Plate 26, fig. 5, 



As the key indicates, this species is probably most closely related 

 to H. rohustus and to H. Jiamiltoni, having fewer gill-rakers and fewer 

 fin rays than in H. elassodon or H. duhius. H. propinquus differs 

 from the type of H. rohustus in the much slenderer body; in having 

 both sides with most of the scales ctenoid, and in the prominent nasal 

 tubes. According to Jordan and Evermann's description of the type 

 of H. rohustus, it has the depth 2 J in length without caudal (0.47 

 as measured on the same specimen by Gilbert); "no ctenoid scales 

 on the blind side" ; "no exserted nasal tubes." H. propinquus differs 

 from H. Jiamiltoni in the shorter pectoral, less than half as long as 

 head, and in the more weakly ctenoid scales. The pectoral of the 

 blind side is covered with ctenoid scales in the adult of H. Jiamiltoni, 

 but always naked in this species. The differences are more apparent 

 in the young. Specimens of the same size when compared with the 

 type of H. Jiamiltoni differ strikingly in the much shorter fin rays, 

 especially the pectoral, and in the more weakly ctenoid scales, those 

 of the blind side nearly smooth instead of strongly ctenoid. The eye 

 is also smaller, 4.25 instead of 3.5 in head. 



Type-specimen.— Oat. No. 75667, U.S.N.M. A female 327 mm. 

 long without caudal, 383 mm., with caudal. Alhatross station 5005, 

 Aniwa Bay, Sakhalin Island.
