streak at bases of upper rays of upper caudal lobe. Dorsal dusky, and 

 with a median longitudinal pale line. Pectoral and ventral brownish, 

 a little paler than caudal, and latter with a broad diffuse pale tint 

 transversely and medianly. Anal pale brownish. Iris slaty with a 

 narrow inner pale circle adjoining pupil. Length 3^ inches. 



Six examples. The five other examples show the following: Head 

 4^ to 5; depth Ah to 5; scales 26 or 27 in lateral line to base of caudal, 

 usually 2 more on latter; snout about 2, seldom a little more; eye 3| 

 to 4; total length 2^ to 2| inches (54 to 73 mm.). 



34. Lobooheilos hispidus (Valenciennes). 



Head 4f ; depth 4; D. iv, 8, i; A. iv, 5, i; scales 34 in lateral line to 

 base of caudal, and 2 more on latter; width of head 1^ in its length; 

 depth of head, at anterior margin of orbit, 2; snout 2^; eye 4|; inter- 

 orbital space 2; width of mouth 2^ ; least depth of caudal peduncle If; 

 length of depressed dorsal 3^ in head and trunk; length of lower caudal 

 lobe 2f ; length of pectoral 4; length of ventral 3^\; length of anal, 3|. 

 Length 7f inches. 



A single example which agrees with Bleeker's figure,^ though there 

 are more pores on the snout than he represents.

35. Labeobarbus douronensis ( Valenciennes ).^7 



Head 3^; depth 3; D. iii, I, 8, i; A. iii, 5, i; scales 19 in lateral hue 

 to base of caudal, and 2 more on latter; 8 scales before dorsal; width 

 of head 2 in its length; snout 3; eye 4; interorbital space 3^ ; mouth 

 3^; least depth of caudal peduncle 2^; pectoral 1^; ventral 1^. 

 Length 6| inches. 



A single example which agrees with Bleeker's figure.^ It will be seen 

 to differ in the deeper body and higher back. There are no dark dots 

 on the upper surface of the body, which is darker brown than the lower, 

 in my example. 



36. Cyclocbeiliclitliys megalops sp. nov. 



Head 3; depth 3; D. iii, I, 8; A. iii, 6; P. i, 18; V. i, 9; scales 32 

 in lateral line to base of caudal, and 3 more on latter; 12 scales before

3' This name is proposed in place of Barbimc for the Barbels, as Mystus Klein, in 

 Walbaum, Pei. Arted. Pise, III, 1792, p. 586, is much older than Barbus. Wal- 

 baum's name is considered typified by Cyprinus barbus Linnaeus. 



3' SiAJA MiCROLEPis (Bleeker) . 



One in the Academy from the Paris Museum. Bleeker's figure does not indi- 

 cate the striae on the head which are well displayed in this example. The upper 

 margin of the dorsal is also dusky. Borneo.
