of Leeds and its Vicinity. 393 



of the county ; our share therefore consisting, with two or three ex- 

 ceptions, entirely of freshwater fish. 



ACANTHOPTERYGII. 



Perca fluviatilis. Pretty generally dispersed. 



Acerina cernua. Pretty generally dispersed. 



Gasterostcus aculeatus, trachurus, semiarmatus . Plentiful. In most 

 ponds, especially those in the neighbourhood of brick fields. 



—— — — Pungitius. Not uncommon at Campsall, as I am in- 

 formed by Dr. Lankester. 



Malacopterygii Abdominales. 



Cyprinus Carpio. Not uncommon in most ponds and lakes. 



Gibelio. I have received this fish of various ages, from 



the same localities as the following species : 

 ' auratus. Exceedingly abundant in many of the reservoirs 



belonging to the factories, into which the water from the steam- 

 engines is let off for the purpose of being cooled. 



Barbus vulgaris. Not uncommon in running streams at Hare wood, 

 Bolton, Castleford, and Wakefield. 



Gobio fluviatilis. Plentiful. 



Tinea vulgaris. Rather locally dispersed, Kippax, Temple Newsam. 



Abramis Brama. Not uncommon. Ferrybridge, Cawood. Our spe- 

 cimens have only 52 scales in the lateral line, while Mr. Yarrell 

 describes 57. 



— — Blicca. Rare. We have a single specimen caught at Ca- 

 wood, but in the neighbourhood of Campsall I believe it is not 

 luicommon. 



Leuciscus rutilus, vulgaris. Common. 



leucophthalmus ? Not uncommon. This, which appears to 



be a new species of Leuciscus, was detected by T. P. Teale, Esq. 

 F.L.S. of Leeds. It approaches, in some respects, the Dobula, 

 but not sufficiently to enable us to decide it as that species. It 

 has been generally overlooked as the Dace, but dilFers from that 

 fish in many material characters, as the proportion of the pec- 

 toral fins to the entire length, the situation of the dorsal, the 

 number of scales both in the lateral line and above and below it, 

 which I shall not now describe, as it is most probable Mr. Teale 

 will minutely enumerate its distinctive characters ; in the mean- 

 while he has named it provisionally leucophthalmus. 



Leuciscus Cephalus. Common.
