86 MALACOP. ABDOM. CARP FAMILY. 



in the clear streams of Wiltshire, and Mr. Jenyns 

 has met with it in considerable numbers in the Cam, 

 and in fish-ponds at Ely ; Mr. Thompson, also, has 

 found it in Warwickshire. Its existence in Scotland 

 has by no means been satisfactorily ascertained, Dr. 

 Parnell only saying, I rather think that a specimen 

 came under my observation in the Teith, but I 

 failed in obtaining it. The form of the body is more 

 elongated, slender, and compressed, than that of the 

 Barbatula; the nose more pointed; the pectorals 

 longer and narrower. The colours are similar ; but a 

 row of dark spots, ranged along the sides, is more 

 conspicuous. It seldom exceeds three inches in 

 length; it spawns in April or May, depositing its 

 ova among stones at the bottom of the stream.
