798 MR. F. DAY ON THE FISHES OF YARRAND. [Dec. 5, 



the broken state of its caudal fin, must be accepted as the reason 

 why my proportion of the free portion of the tail does not agree 

 with Dr. Gunther's (nearly |) ; whilst I find the caudal fin emar- 

 ginate, and not " rounded." 



19. Nemacheilus gracilis, sp. nov. 

 B.iv., D.f, P. 13, V. 8, A. % C. 17. 



Length of head 5i, of caudal 6^-, height of body 6^ in the total 

 length. Eyes: diameter 1 1 in length of head, 4 diameters from end 

 of snout, and 2\ apart. Snout overhanging the mouth. The 

 greatest width of the head equals its height or its length excluding 

 the snout. Lips thickened ; lower labial fold interrupted in the 

 middle and rather lobed on either side. Barbels six ; the maxillary 

 ones nearly twice as long as the eye ; the external rostral ones 

 reach the hind nostril ; the other pair are shorter. Fins : dorsal 

 commences midway between the eye and vertical border of the preo- 

 percle ; its upper edge is nearly straight ; it is not quite so high as 

 the body below it, and one fourth less than the extent of its base. 

 Pectoral as long as the head behind the angle of the mouth ; it 

 reaches rather above halfway to the base of the ventral, which latter 

 fin arises somewhat in advance of the commencement of the dorsal ; 

 it is of about the same length as the pectoral, and extends halfway 

 to the anal. Anal twice as high as wide at its base ; it reaches, when 

 laid flat, a little more than halfway to the base of the caudal, which 

 is slightly emarginate. Free portion of the tail half as high at its 

 base as it is long. Scales absent. Colours : brownish along the 

 back, becoming yellowish beneath ; dorsal and caudal with dull spots.

B.iv., D.f, P. 11, V. 7, A. | C. 17. 



Length of head 4f to 5, of caudal 7, height of body 7 in the 

 total length. Eyes: diameter 5 in length of head, 2 diameters from 

 end of snout, and lg apart. Snout somewhat pointed; and in some 

 the preorbital is slightly projecting. Lips wrinkled ; the lower 

 labial fold interrupted. The greatest width of the head equals its 

 height or its length excluding the snout. Barbels : the maxillary 

 ones reach to below the hind edge of the eye ; the rostral ones are 

 nearly as long. Fins : dorsal commences midway between the end 

 of the snout and the base of the caudal ; its upper edge is nearly 

 straight, oblique, and with rounded angles ; its height rather ex- 

 ceeds that of the body below it ; and it is nearly twice as high as its 

 base is long. Pectoral as long as the head excluding the snout, and 

 extending halfway to the ventral. Ventral one third shorter than
