Hypophthalmichthys molitria;, C. V. 

 Vernacular name : Chiang pan tou yu. 



Opsariichthys Morrisonii^ sp. n. (PI. XIII. fig. A.) 

 D. 10. A. 10. L. lat. 48. L. transv. 9/5. 



Head compressed, deep, its depth being two thirds of its 

 length. The eye is immediately below the upper profile, 

 distant more than two diameters from the angle of the 

 mouth ; it is small, one seventh of the length of the head, 

 and two fifths of that of the snout. Interorbital space flat, 

 2^ times as wide as the orbit. Mouth wide, the maxillary 

 extending to below the middle of the eye. The end of the 

 lower jaw is received in a notch of the upper, and has on each 

 side in front a notch to receive a strong projection of the 

 upper jaw. The third, fourth, and fifth anal rays are pro- 

 longed into a lobe which reaches the base of the caudal. 

 Origin of the dorsal opposite to that of the ventral, but only 

 very little nearer to the root of the caudal than to the end of 

 the snout. Caudal deeply forked. The pectoral does not 

 extend to the ventral. The depth of the body and the length 

 of the liead are a little more than one fourth of the total length 

 (without caudal). Suborbital ring broad, its width below 

 the orbit being equal to that of the orbit. Silvery. 



The specimen is 9 inches long, fully mature, and was 

 caught during the breeding-season, the lower jaw and other 

 parts of the head being beset with small dermal tubercles. 

 The species is allied to 0. bidens, and bears the Chinese name 

 of Fai-Jcu yu. For comparison the latter species is figured 

 on PI. Xlll. fig. B ; it has been described in Ann. & Mag. 

 Nat. Hist., Sept. 1873, p. 249. 



Culler erythropterus. 

 Vernacular name : Pai yu. 



Culter erythropterus, Basil. Nouv. Mem. Soc. Imp. Nat. Mosc. x. 1855, 



p. 236, tab. viii. fig. 1 ; Giiutli. Fish. vii. p. 328. 

 Culter ilisha-formis, Bleek. Nat. Verh. Ak. Wet. xii. ; Cyprin. Chin. 



p. 67, tab. X. fig. 1 ; Giinth. Ann. & Mag. Nat. Hist., Sept. 1889, 



p. 227. 

 Cvlter Sieboldii, Dybowski, Verh. zool.-bot. Ges. Wien, xxii. 1872, 



p. 214 (is probably the same fish). 



Having now had the opportunity of comparing a specimen 

 from Northern China with others from the Yangtsekiang, I 

 have convinced myself of their specific identity. Bleeker's 

 first description in Ned. Tijdschr. Dierk. ii. p. 27, was faulty.
