DESCRIPTION OF A NEW CYPRINOID FISH, HEMI- 



BARBUS JOITENI, FROM THE PEI HO, 



TIENTSIN, CHINA 



By DAVID STARR JORDAN and EDWIN CIIAPIN STARKS 



A collection of fishes from the Pei Ho at Tientsin, China, made 

 by Prof. Noah Fields Drake, of the University of Tientsin, was 

 sent in 1898 to the Museum of Leland Stanford Junior University. 

 These fishes were studied by Mr. James Francis Abbott, and a 

 report published by him in the Proceedings of the U. S. National 

 Museum, vol. xxiii, 1901. The specimens called by Abbott (p. 487) 

 Hcniibarbus harhiis, seem distinct from the Japanese species of that 

 name. We propose for them the new specific name — 



HEMIBARBUS JOITENI Jordan and Starks, new species 



(Plate LXIV) 



Head 4 in length to base of caudal; depth 4}/%. Dorsal iii^ 7 

 (the last ray divided to its base) ; anal 8 ; lateral line scales 48. 



Body rather robust; a slight hump developed at nuchal region. 

 Snout rather sharp as viewed laterally; projecting beyond mouth 

 a distance slightly exceeding half the diameter of eye. Lips thick 

 and papillose in large specimens ; lower lip with a backward pro- 

 jecting median flap. Length of maxillary barbel is from half to 

 two-thirds of the diameter of the eye. Teeth in three rows ; the 

 outer row large ; the two inner rows small ; the first with five teeth, 

 the second three, and the inner row with one. Anterior nostril 

 ending behind in a broad flap which nearly closes posterior nostril. 

 Large sensory canals follow the lower edge of the suborbitals and 

 the edge of the preopercle, extending around the under side of the 

 snout and mandible ; they open to the exterior at rather wide in- 

 tervals along their length through very small pores. Interorbital 

 space rather wide, from i^ times diameter of eye in small speci- 

 mens to nearly 2 in large ones ; in the latter 3 slight longitudinal 

 ridges are developed ; a median ridge and a ridge at each side 

 between outer- edges of frontals and supraorbitals. There are 7^ 

 scales in the backward downward series from first dorsal spine to 

 lateral line and 6^ in a like series from front of anal to lateral
