480 PROCEEDINGS OF THE ACADEMY OF [July, 



taken by Harrison and Hiller in 1897, has: Head 3-| ; depth 2f ; D. ii, 

 18; A. Ill, 6; scales 50 to base of caudal, 2 more on latter; length 7i 

 inches. It agrees well with Bleeker's figure in the color pattern. 

 Three other examples from the Baram river, one, taken by Dr. Furness 

 in November, 1898, measures 20^ inches, while the others, secured by 

 Harrison and Hiller, measure 19 and 24 inches respectively. They 

 show: Head 3f ; depth 2f to 3; I), iv, 16 to 18; A. in, 6; scales 41 to 

 44 in lateral line to base of caudal, and 5 or 6 more on latter; 10 scales 

 between origin of dorsal and lateral line and 8 obliquely forward from 

 origin of anal to latter; width of head 1|^ to If in its length; snout 2f to 

 2f ; eye 5^ to 51; interorbital space about 2; least depth of caudal 

 peduncle If to 2. Dr. Furness's example shows the bases of all the 

 fins, at present in alcohol, pale buff with a slight pinkish tint. The 

 silvery spots of the smaller example from the Kapuas are not evident. 

 Also another example, lOj inches long, from Dr. Furness. It was 

 taken in the Baram river in 1897. 



31. OsteocMlus kappenii (Bleeker). 



Head 3|; depth 2h; D. iv, 17; A. in, 6; scales 29 in lateral line to 

 base of caudal, 3 more on latter; 5^ scales between origin of dorsal and 

 lateral line, and 4^ between latter and origin of ventral ; width of head 

 1^ in its length ; snout 3 ; eye 4 ; interorbital space 2. Snout short and 

 broad, obtuse, and its length in profile but little more than diameter of 

 eye. Back well elevated, nape well convex, and upper anterior profile 

 steep and straight. Pectoral long, nearly reaching origin of ventral. 

 Along each series of scales longitudinally a well-defined brown band. 

 On caudal peduncle at base of caudal traces of a brown spot. One 

 example 3|- inches (about 98 mm.) in length. 



This example seems to agree somewhat with the notes under Osteo- 

 cMlus kahajanensis of Dr. Steindachner from the Baram river. In 

 Bleeker's original account^^ the depth will be seen to be a little over 4 

 in what is presumably the total length, while the head is given as 5^. 

 Bleeker's figure,^^ published later, agrees except that the head is a little 

 larger. Dr. Steindachner gives the depth^* as 2f to 2|, which is cer- 

 tainly not in agreement with kahajanensis. 

 82. Osteochilus harrisoni sp. nov. 



Head 3|; depth 2^; D. ii, 16; A. iii, 5, i; P. i, 15; V. i, 8; scales 

 33 in lateral line to base of caudal, and 2 more on latter; 6 scales be-
