bands on the back. A black interrupted band at the root of 

 the caudal. Dorsal rays with series of black spots. Anterior 

 dorsal rays often with a larger one. Length about 90 mm.

Note. We have included N. saravacensis in the synonymy 

 of N. fasciatus as the differences, given by BOULENGER, do 

 not hold good. The difference in the number of the dorsal 

 rays is not noteworthy. We find in specimens of N. fasciatus 

 (from Java) the origin of the dorsal above the origin of the 

 ventrals or slightly before them, but never behind. 



After inspection of the young specimens in the Leiden 

 Museum, which VAILLANT calls Nemachilus rupicola Me Clell. 

 whitout giving any reason for this definition, we believe that 

 they belong to Nemachilus fasciatus C. V. 



Dr. GESTRO, Director of the w Museo Civico" of Geneva has 

 been kind enough to send us two typical specimens of Modi- 

 gliania papillosa Perugia. We are obliged to unite it with 

 Nemachilus fasciatus, as we cannot see the "papilla grossa 

 conica, lunga meta il diametro dell' occhio alia regione prae- 

 orbitale" and otherwise there is no difference from Nemachilus 

 fasciatus.

Height 5.6, 7 in length with caudal. Head 4.5, 5.6 in length 

 with caudal. Eye 5, twice in length of snout, about I '/ 5 in 

 interorbital space. Inner rostral pair of barbels shorter than 

 the outer ones, extending to middle of operculum. Origin of 

 dorsal originating above the base of the ventrals, and slightly 

 nearer the end of the snout than the base of the caudal. Height 

 of dorsal somewhat less than length of head. Anal halfway
