 its stiff portion equal to head. Anal slightly emarginate, third 

 spine^ shorter than head. Pectorals and ventrals subequal, 6^4 — ■/

 anal, separated by 4 — 4'/2 scales from lotli scale of lateral line. 

 Caudal deeply forked, lobes pointed, somewhat longer than 

 head. Least height of caudal peduncle less than its length, 

 more than twice in length of head, surrounded by 16 scales.

I) In the Atl. Ichth. III. plate CXXXVI. (Cypr. XXXV; the figures of 

 Puntius schzuajiefeldi and C. inacropus are interchanged ; this explains the mistake 

 of Vinciguerra (Ann. Mus. Civ. Geneva XIV. 1879, p. 389), who wrongly iden- 

 tified specimens of F. schwanefeldi as C. inacropus.
