TWO SPECIES OF CHINESE FISHES— GINSBURG. 



101 



do not quite reach so far in the type. Origin of anal fin sUghtly 

 posterior to that of second dorsal, both fins ending on same vertical. 

 Caudal rounded, not prolonged. Anal papilla oblong, triangular, 

 slightly bifid in type, truncate in paratype, its length about equal to 

 half diameter of eye. 



Head brownish, nape marbled with darker. One or two very in- 

 distinct longitudinal lines on upper part of opercles, two or three such 

 lines on nape directly over opercle, more distinct. The exposed part 

 of every scale with a large brown spot anteriorly, the margin yellow- 

 ish. Fins dusky, the spinous dorsal darkest. Dorsals, anal and 

 caudal margined with light yellowish; a rather indistinct yellow band 

 at base of pectoral. Five very indistinct crossbars on body behind 

 pectorals. An oblong spot more or less distinct at base of caudal. 

 The entire body and fins are stippled with very minute dark spots. 



Two specimens from the Yalu River collected by Arthur de C. Sow- 

 erby. 



FIolotijpe.—68 mm. long. Cat. No. 76734, U.S.N.M. 



Paratype.— Q5 mm. long. Cat. No. 76734-^, U.S.N.M. 



This species is very near Rliinogobius nagoyae, Jordan and Seale,^ 

 rom Nagoyae, Japan. It differs from that species in that the fourth 

 dorsal spine is the longest instead of the second. The longest spine 

 in the present species is about one-half the head instead of nearly 

 equal to it. The soft dorsal and caudal lack the regular rows of spots 

 present in the older species.
