Annals of the Carnegie Museum. 



it is provided with four rather long barbels, it is incorrect to include it 

 in the genus Gymnostomiis. 



In October of the same year Regan described Gymnostomus labiatus 

 from the same locality. According to his description it differs from 

 the former in having lower lips which are separated anteriorly by a 

 deep narrow notch instead of being separated widely. In my speci- 

 mens which came from the type locality and other places, the width of 

 the inter-space between the lower lips is not definite; even in the 

 specimens which came from the same locality there are deviations 

 with regard to that character. Therefore it seems inadvisable to 

 separate the two forms.

Body elongate, slightly compressed. Snout rounded, tip of the 

 skin extends downwards and partially overlaps the upper lip. Mouth 

 transverse, inferior, lower jaw with no lip, its anterior margin sharp 

 and covered with a horny brown layer. Barbels two, ninute, at the 

 corner of the mouth. Dorsal fin without osseous rays, with not more 

 than nine branched rays, opposite to the ventrals. Anal fin rather 

 short. Scales large, less than fifty in a longitudinal series. Pharyn- 

 geal teeth in three rows, 5, 3, 2-2, 3, 5. Lateral line running along 

 the middle of the tail. 



Distributiofi: Formosa; Hainan. 



Re7iinrks: The type of the present genus is closely related to the 

 species of Scaphiodon. It differs, however, in having larger scales and 

 no osseous dorsal ray. 



In the year 1899, Boulenger described a species of Cyprinoid fish
