radiated striations; lateral line nearly straight, extending along the 

 middle of sides from base of the caudal to the upper part of gill- 

 opening. 



Color in alcohol uniformly dark grey above, sides and lower parts 

 silvery; dorsal and caudal fins grayish; other fins dusky white; scales 

 on the upper part of body with a black lunar-shaped spot near the 

 base. 



Total length 340 mm. 



Described from a specimen from the hatchery at Shori. 



Habitat: A species introduced from China, propagated throughout 

 the island, and bred artificially in ponds. 



Remarks: The nearest relative of the present species is Labeo decorus 

 Peters from Hongkong. It difi"ers, however, in having an upper lip 

 which is fringed at the sides only, and a distinctly fringed lower lip. 



Jordan and Evermann recorded a Formosan species of the genus 

 Labeo under the name Rohita decora {— Labeo decorus Peters). The 

 descriptions given by these authors are very inadequate. But the 

 briefly described characters, except the number of rays of the pectoral, 

 agree quite well with those of the present species. Moreover, as 

 there is no record with reference to the occurrence of any species of 

 Labeo in Formosa except the introduced species, it seems reasonable 

 to unite Jordan & Evermann's Rohita decora, which distinctly differs 

 from Peters' Labeo decorus,'^ with the present species. 



In the year 1910, Mr. Seno, Expert of the Fisheries Bureau of the 

 Japanese Government, described the present species, giving it the 

 name Labeo kontius (Jordan). (Cf. Report on the Fisheries of the Island 

 of Formosa). The Indian species of that name distinctly differs from 

 the Formosan species in having a higher body, longer head, tuber- 

 culated snout with a fleshy lateral prolongation, fringed lower lip, 

 and no barbels. 



Such being the case, I propose for the present species a new name 

 Labeo jordani. 



"Kenhii" is one of the important fresh-water food-fishes in For- 

 mosa, though it is not a native of the island. Early in the summer, 

 newly hatched larvae of this fish are collected in the rivers near Swatow, 

 South China, and are imported to Formosa. At first they are bred in 

 small ponds, living mainly upon zoo-plankton, the growth of which is 

 encouraged by human excrement. As soon as they are large enough to
