Iris slaty. Nasal and maxillary barbels whitish mostly, brownish 

 above, and mental barbels entirely white. 



Length 1| inches. 



Type No. 14,149, W. I. A. P. Baram river, Borneo. 1898. Dr. 

 W. H. FiArness. Also 25 paratypes with same data. 



From Akysis armatus Vaillant^^ it differs in the coloration, that spe- 

 cies having round pale spots. 



This species shows great color variation in alcohol, some examples 

 are almost black, the contrast between the coloration above and below 

 being very pronounced, while in others this is rather obscure. Other 

 examples have the blotches on the body distinct, and also those on the 

 fins, while others are more or less unicolored. The amount of blackish 

 or brownish on the ventrals also varies, in some examples these fins 

 are noticeably dark, while those of others are pale. The largest exam- 

 ple measures a little over 2 inches. 



(Named for the Baram river in British Borneo.) 



OOBITIDID^. 

 COBITIDIN.E." 

 25. Botia macracantha (Bleeker). 



The oblique dark brown band on head not so pronounced as in 

 Bleeker's figure.^* Anterior margins of pectoral, ventral and anal 

 pale like belly. Color of smaller examples agrees best. Three from 

 the Kapuas rivei-. Harrison and Hiller.

" Prof. Vaillant has recently given an exposition of the differential characters 

 of the fishes of this family. He divides them into two groups based on the 

 presence and absence of the preorbital spine. This appears certainly to be of 

 subfamily value. His Enopla will then correspond to the Cobitidime as proposed 

 above ^\'hich may be t\'pified by C'obitis Linnanis [type Cobitis tcenia Linmeusl. 

 This group has the erectile spine on the side of the head. Tlie other Loaches, or 

 Anopia, may be known as subfamily: 



MISGURNIN./E. 



No erectile spine on side of head. Typified by Misgurnus Lac^pfede. A 

 species belonging in this group has recently been described by Prof. Vaillant. 

 It appears to differ from Nemacheilus Van Hasselt, and may be indicated as a 

 new genus. 



VAILLANTELLA gen. nov. 

 Type Xeinaclteilus euepipterus Vaillant. 



It is closely related to N^emacheilus, differing at once in the long dorsal basis, 

 tlie radii numbering about 6-4. 



(Named for Prof. Leon Vaillant, tlie distinguished ichthyologist of the Museum 

 of Natural History of Paris, and well known for his researches in East Indian 

 ichthvologv.)
