D. 10. A. 11. L.lat. 70-72. L. transv. 15/?. 



The height of the body is rather more than one-fifth of the total 

 length (without caudal). The width of the interorbital space is 

 more than the diameter of the eye, and about one-third of the 

 length of the head. The cleft of the mouth does not reach the 

 vertical from the front margin of the eye. Snout scarcely convex, 

 the upper jaw but slightly overlapping the lower. Origin of the 

 dorsal lin opposite to the root of the inner ventral ray. There are 

 five or six longitudinal series of scales between the lateral line 

 and ventral fin. A dark band along the side of the head and body, 

 above the lateral line. Fins orange-coloured at the base. {Heck.) 



Dalmatia. 



Squalius microlepis, Heckel, I. c. p. 1042 ; Heck. &, Kner, I. c. 

 p. 202. fig. 114, from the same country, is probably not specifically 

 distinct from L. fio-sl-yi, and founded on examples without the 

 lateral band, whicli also in L. muficeUus so frequently disappears. 



Prof. Canestrini (Arch. p. la Zool. etc. iv. 1866, p. Ill) regards 

 S. ukliva, microlepis, turskyi, and tenellus as being one and the 

 same species. 



31. Leuciscus tenellus. 



Squalius tenellus, Heckel, in Hifsset/f/er's Reisen, i. p. 1042 ; Heck. S( 

 Kner, Siissivasserf. p. 204. fig. 115. 

 D. 10-11. A. 11. L. lat. 78-80. L. transv. 18/?. 



The height of the body is rather more than one-fifth of the total 

 length (without caudal). The width of the interorbital space is more 

 than the diameter of the eye, and a little less than one-third of the 

 length of the head (namely, the diameter of the eye equals two-thirds 

 of the interorbital space, or equals one-fifth or two-elevenths of the 

 length of the head). The cleft of the mouth does not quite reach 

 the vertical from the front margin of the eye. Snout not convex, 

 the upper jaw scarcely longer than the lower. Origin of the dorsal 

 fin opposite to the root of the inner ventral ray. There are eight 

 longitudinal series of scales between the lateral line and ventral fin. 

 Coloration uniform, bluish grey. {Heck.) 



Livno (Bosnia). 



32. Leuciscus vanensis. 



D. 11. A. 12. L. lat. 09. L. transv. 12/8. 

 The height of the body is a little more than one-fifth of the total 

 length (without caudal), the length of the head nearly one-fonrth. 

 The diameter of the eye is two-ninths of the length of the head, 

 equal to that of the snout, and three-fourths of the width of the 

 interorbital space. Cleft of the mouth very oblique, not reaching 

 to the vertical from the front margin of the orbit ; lower jaw 

 slightly overlapped by the upper, but projecting beyond it when
