112 The Fishes of Cambridgeshire 



25. Rudd, Leuciscus erythrophthalmus (Linn.). 



26. Tench, Tinea vulgaris (Cuv.). 



27. Bream, Abramis brama (Linn.). 



28. White Bream or Breamflat, Abr< 's- Idicca (Cuv.). Tins 



species was first observed in this country in 1824. 

 Specimens were obtained from the Trent. The Rev. 

 L. Jenyns subsequently found the fish existing in the 

 Cam. It is a much smaller species than the common 

 Bream and far less widely distributed. Mr Brindley of 

 St John's College once took a specimen of the White 

 Bream normal in every way save that it lacked the 

 pelvic fins and girdle: it was nevertheless in as good 

 condition as others obtained from the same shoal. 

 This abnormal fish has been placed in the Museum 

 of the Royal College of Surgeons. 



29. Pomeranian Bream. Stated to exist in the county by 



Houghton and Cholmondley Pennell. 



30. Bleak, Alburnus lucidus (Giinther). 



31. Loach, Nemachilus barbatulus (Giinther). 



32. Spined Loach, Cobitis taenia (Linn.). Yarrell says it 



has been found in Cambridgeshire. 



33. Pike, Esox Indus (Linn.). 



34. Allice Shad, Clupea alosa (Linn.). Doubtful. There is 



a specimen in the Wisbech Museum, but the locality of 

 capture is not mentioned. 



35. Twaite Shad, Clupea finta (Linn.). Doubtful as a Cam- 



bridgeshire fish. One specimen was taken, 1854, in 

 the Nordelph River. 



36. Salmon Trout, Salmo trutta (Linn.). One specimen, 



1849, Wisbech. 



37. Trout, Salmo fario (Linn.). Plentiful in south of county. 



38. Smelt, Osmerus eperlanus (Linn.). 



39. Eel, Anguilla vulgaris (Turk). 



CHONDROSTEI. 



40. Sturgeon, Acipenser sturio (Linn.). Occasional. I have 



heard of seven specimens being taken in the Great
