grayish, evidently silvery. An elongated deep-brown blotch, a little 

 longer than eye, about level with latter's upper edge just behind 

 gill-opening. Behind this an indistinct pale streak, margined narrowly 

 above from about opposite base of ventrals almost to caudal base 

 with a narrow blackish line. Dorsal pale brownish with about 3 pale- 

 dusky blotches on each ray, forming as many longitudinal series of 

 spots, though upper 2 rows closer together. Other fins all plain 

 pale brown. 



Length 2h inches. 



Type, No. 29,468, A. N. S. P. Pei Ho River, at Tien Tsin, China. 

 N. F. Drake. From Stanford University. 



Also Nos. 29,469 to 29,471, paratypes, same data. Head 3f to 4; 

 depth 2f to 2f; D. hi, 14, i once, iii, 12, i, usually; A. ii, 10, i; scales 

 33 or 34 + 2; 6 scales above 1. 1.; 5 scales below 1. 1.; 15 or 16 

 predorsal scales; snout 3^ to 4 in head; eye 2f to 3^; maxillary 3$ 

 to 4; interorbital 2f to 2f ; teeth 5-5; length 2|- to 3f inches. 



Related to Paracheilognathus imberbis Bleeker, but differing chiefly 

 in the presence of the dark shoulder blotch. Bleeker's description 

 fails to note this character, and his figure 5 also does not indicate 

 it. His example has been thought by Giinther 6 to be different from 

 the latter's Achilognathus imberbis 7 , which is said to have both dorsal 

 and anal radii 12. Paracheilognathus rhombeus (Schlegel) from 

 Japan, differs from my species in having maxillary barbels and more 

 scales below the 1. 1. Acanthorhodeus dicaus Rutter from Swatow, 8 

 agrees with this latter in having maxillary barbels, and is therefore 

 not identical. 



(Named for the Pei Ho River, in the Province of Pechili, China.)
