Steindachner, Catal. pj-elim. Tuiss. cVeau douce de Portugal {Mem. 

 Acad. Sc. Lisbon. 1866), p. 3, and Sitzffsber. Ak. Wiss. Wien, 1866, 

 liv. p. 7, taf. 1. 



D. 3/8. A. 3/5. L. lat. 47-52. L. transv. 9/9. 



Third dorsal spine rather feeble, finely serrated. There are five 

 longitudinal series of scales between the lateral line and the base of 

 the ventral. Body moderately elongate ; snout much produced, 

 with thick lips. Eyes small. Anal fin at least twice as high as 

 broad. Coloration uniform ; young specimens irregularly marbled 

 and spotted with brown. 



Pyrenean peninsula. 



a-e. Adult, half-grown, and young. Coimbra (River Mondego). 

 Presented by Dr. Barb, du Bocage. 



The author quoted believes he has found Jiyhnds between this 

 species and Clioyulrostoma polyJeiris, which have all the other cha- 

 racters of the Barbel, but the jaws and mouth of Chondrostoma. 

 This observation requires to be confirmed ; such a combination of 

 characters is found in Cyprinoid genera of Western Asia, which are 

 certainly not hybrids. 



15. Barbus caUensis. 



? Barbus leptopogon (Agassiz, Prodrom.), Bonap. Faun. Hal. Pesc, 



figure without description. 

 ? Barbus callensis. Cm: ^- Val. xvi. p. 147. 



D. 3/8-9. A. 3/5. L. lat. 48-50. L. transv. 9/11. 



Third dorsal spine very strong, strongly serrated. There are six 

 longitudinal series of scales between the lateral line and the base of 

 the ventral. Body oblong, rather compressed ; snout not produced, 

 with the cleft of the mouth subterminal and of moderate width ; 

 Ups thin. Eye of moderate size. Anal fin at least twice as high as 

 broad. 



Spain (River Tajo) ; Algeria. 



a-h. Half-grown and young. Algiers. Purchased of M. Parzudaki 

 as B. callensis. 



I have not been able to find the original notice of Agassiz's B. 

 leptopogon, which, however, according to Valenciennes, appears to 

 be but short and insufficient. Bonaparte does not state whether 

 the figure published by him in the ' Fauna Italica' is taken from 

 the typical specimen or from an example in some other collection. 

 That figure agrees with the description given by Valenciennes of B. 

 callensis in representing the scales larger than those found in the 

 other species of this division of the genus, the lateral line being 

 composed of about forty scales. However, the Algerian specimens 

 in the British Museum, received with the name of B. callensis, have 

 forty-eight scales ; and a reexamination of the examples in the 

 Paris Museum may show that B, callensis really has this number of 

 scales.
