Note. We dont think that the specimens from the Baram 

 river, Borneo, which Fowler (Proc. Acad. Nat. Sc. Philad. (2) 

 LVII. 1905, p. 486) called R. leptosoma, belong to this species, 

 as he gives 4 for the head and L. 1. 27. His description is 

 too short to be able to decide, to which species these 

 specimens belong.

Height 4 4.4; 5 7 in length with caudal; head equal to 

 height. Eye 3.4 to more than 4, equal to or shorter than snout, 

 and 1.4 1.8 times in nearly flat interorbital space. Cleft of 

 mouth obliquely ascending, its anterior end in the level of 

 the superior border of the eye, its posterior end not reaching 

 vertical through frontborder of eye. Notch on the border of 

 the upper lip very deep, receiving the strongly developed 

 symphysial knob. Origin of dorsal somewhat before middle 

 between snout and last caudal scales, opposite to 12 th lateral 

 scale, separated from head by n or 12 scales. Dorsal truncate, 

 its height about equal to height of body, nearer to ventrals 

 than to anal. Anal concave, its height somewhat less than 

 height of body. Ventrals opposite to io th lateral scale, not 

 reaching anal, their distance from anal somewhat less than 

 their distance from operculum. Pectorals about equal to distance 

 from nostril to hindborder of operculum, the distance between 

 their tip and the origin of the ventrals less than diameter of 

 eye. Caudal somewhat longer than head, deeply incised. Least 

 height of caudal peduncle twice in its own length and more 

 than postorbital part of head; 7 rows of scales between the 

 lateral lines, counted over the back of the middle of the caudal 

 peduncle. Colour brownish, lighter below, scales of back and 

 sides with a dark streak at their base. A median black dorsal 

 line. Fins dark. 



A variety with a black longitudinal lateral band from head 

 to tail is described by Miss POPTA (Notes Leyden Museum, 

 XXV. 1904 05, p. 176; ibid. XXVII. 1906, p. 161) as Ras&ora 

 Volzii var. fasciata.
