ii^ferior, and with the lips rather thin. Eyes small. A.nal fin at 

 least tmce as high as broad ; caudal deeply forked. Body immacu- 

 'late. (Heel:) 



River Tigris, near Mossul. 



4. Barbus scheich. 



Luciobarbus scbejcb, Heckel, in Russegger''s Reisen, i. p. 1056, and ii. 

 part 3. p. 215, taf. 15. lig. 1. 



D. 3/8. A. 3/5. L. lat. 59-60. L. transv. 10/7 + .r. 



Third dorsal spine exceedingly strong, strongly serrated, its 

 length being not much less than the height nf the body. There 

 are seven longitudinal series of scales between the lateral line and 

 the base of the ventral. Body rather elongate, the part of the back 

 below the dorsal fin being compressed and somewhat elevated. 

 Snout not produced; mouth inferior, lips thick (the transverse 

 fold of the lower interrupted in the middle). Eyes rather small. 

 The length of the base of the anal is contained more than twice in 

 that of the anterior rays *. Caudal fin deeply forked. Coloration 

 uniform. (HecJc.) 



River Tigris, near Mossul. 



The fish described by Heckel as Luciobarbus mystaceus {I. c. p. 1051, 

 pi. 3. fig. 3) is probably not the same species as Cyprinus mystaceus 

 of Pallas (see p. 82). The specimens are from the Tigris, and 

 evidently most closely allied to L. scheich, from which they appear 

 to differ in having the lower lip developed into a short lobe. How- 

 ever, I direct attention to the fact that in B. hynni the development 

 of this lobe is subject to great variation; and I have no doubt that 

 Heckel would have described the specimens of this species under 

 different names if he had seen them. 



5. Barbus barbulus. 



Heckel, I. c. ii. 3. p. 256. 



D. 11. A. 8. L. lat. 52-54. L. transv. 10/7+^- 

 Third dorsal spine strong, serrated, of moderate length ; the dorsal 

 fin, if laid backwards, exteiids scarcely to the origin of the anal. 

 There are seven longitudinal series of scales between the lateral 

 line and the base of the ventral. Body rather elongate. Mouth 

 inferior; lower lip very broad, with a very short lobule at the 

 symy)hysis. {Heck.)
