membrane of dorsal fin dusky. Young with a dark longi- 

 tudinal lateral band and 5 dark vertical bars on the back. 



Ilah. Nankancho, near Tinghsiang. 



Two specimens, 90 and IGO ram. in total length. 



I have compared these with the types of G. styani, Blgr. 

 {Crossochilus shjani, Bouleng. Proc. Zool. Soc. 1901, i. p. 268, 

 pi, xxiii. fig. 1), from Niug Po, three specimens measuring 

 100 to 130 ram. in total length. 



In these the anterior edge of the horny sheath of the lower 

 jaw is nearly straight, the folds of the lower lip are separated 

 anteriorly by a wider interspace, and the mouth is wider, ^ the 

 width of the head. Tiie snout is considerably shorter than 

 the postorbitai part of the head in G. styani, whereas in 

 G. kreyenberyii it is equal to it in length. Other slight 

 differences are the somewhat shorter head, shorter pectoral, 

 and different coloration of G. styani. 



G. fasciatus, Stdr. (Crossochilus fasciatus, Bteind. 'Denk- 

 schr. Ak. Wien, lix. 1892, p. 372, pi, iv. fig. 2), from 

 Shanghai, is very similar to C. styani. 



Other Chinese species of Gymnostomus are G. macrolepis, 

 Blkr,, from the Yang-tse-kiang, and G. lepturus, Blgr., 

 from Hainan ; in these barbels are absent. 



Gohio icolterstorffi. (PI. IV. fig. 2.) 



Pharyngeal teeth compressed, hooked, 5, 3 — 3, 5. Depth 

 of body 4i in the length, length of head 41. Snout a little 

 shorter than eye, the diameter of which is 24 in the length 

 of head ; interorbital width 4^ in the length of head. Mouth 

 subterminal^ extending to below the nostrils ; barbel as long 

 as the eye. Dorsal II 7 ; origin nearer to tip of snout than 

 to base of caudal ; longest ray a little shorter than the head ; 

 free edge slightly concave. Anal II 6. Pectoral | the 

 length of head ; origin of ventrals a little in advance of the 

 middle of the dorsal. 33 scales in a longitudinal series, 3^ 

 in a transverse series from origin of dorsal to lateral line, 

 2^ between lateral line and base of ventral fin. Brownish ; 

 a silvery lateral stripe; upper scales with dark edges; fins 

 pale. 



Hah. Nankanclio, near Tinghsiang. 



A single specimen, 90 mra. in total length. 



This species is nearest to G. nitens, Gthr., from Shanghai, 

 in which barbels are absent and the eye is smaller. 



Ghjptosternum sinense. (PI. IV. fig. 3.) 

 Depth of body 5^ in the length, length of head 3f. 

 Brcadtii of head 1;^ in its length; snout as long as the post-
