According- to Berg, this fish is very highl}^ esteemed for its delicate 

 flesli. On account of its comparative scarcity, it brings a rather high 

 price ill the markets.

44. CYNOSCION STRIATUS (Cuvier). 

 PESCADILLA. 



Otilithus striatus Cuvier, Regne Animal., 2d ed., 1829, p. 173, note. 



Otolithus gualueupa, Jenyns, Zool. Voy. Beagle, Part IV, Fish., 1842, p. 41 (iVIal- 



donado Bay, Rio Plata). 

 Cynoscion striafus, Berg, Anal. Mus. Nac. Buenos Aires, IV (2d ser., I), 1895, 



p. 56 (Bahia Blanca; Mar del Plata; Montevideo; Maldonado). 



According to Berg, next to Ificrojjogon unduhttus^ this is the most 

 abundant species on the Uruguayan coast, appearing principally in 

 the months of January and February and July and August. 



Berg gives the fin and scale counts as follo^vs: 



D. X-I, 19 to 21; A. II, 9 or 10; scales 56 to 00; and says that the 

 anal often has 2 spines (authors give one only), of which the first is 

 very small and concealed. 



Young Cynoscion regalis usually has 2 anal spines, and probably 

 small examples of the present species usually have 2, the first grow- 

 ing smaller and disappearing with age.
