LENGTH. From three to four inches. 



DESCRIPT. (Form.) Much more compressed than the last species, 

 especially about the head, which is also smaller : thickness of the body 

 only half the depth : profile more convex, the snout appearing somewhat 

 truncated: barbules shorter and less conspicuous: eyes smaller, placed 

 very high on the cheeks ; the intervening space contracted into a narrow 

 elevated ridge : beneath each eye, but a little in advance, a sharp move- 

 able forked spine directed backwards : dorsal and anal fins similar, and 

 similarly situated, but the former with a ray more : pectorals relatively 

 shorter and less developed, not equal to the length of the head; the 

 second, third, and fourth rays not stouter than the others : ventrals like- 

 wise smaller: 



D. 11; A. 9; C. 15; P. 8; V. 7. 



(Colours.) Yellowish, tinged with orange; the back and upper half of 

 the sides spotted and mottled with brown; more particularly a longi- 

 tudinal series of large round spots on the lateral line, a second on the 

 dorsal ridge, and a third intermediate between these two ; those on the 

 lower part of the back, between the dorsal and caudal fins, sometimes 

 assume the appearance of short transverse bars : dorsal and caudal spot- 

 ted ; the other fins plain. 



Much less frequent than the last species. Found in the Trent in 

 Nottinghamshire, and, according to Turton, in the clear streams of 

 Wiltshire. I have also met with it in some plenty in the Cam, as 

 well as in fish-ponds at Ely. Keeps near the bottom, and appears to 

 reside more in the mud than the C. barbatula. Spawns, according to 

 Bloch, in April and May. Is very tenacious of life.

LENGTH. From two to three feet; sometimes more. 



DESCRIPT. (Form.) Oblong, rather elongated, suddenly narrowing 

 behind the dorsal and anal fins; sides compressed: depth nearly uni- 

 form throughout, about one-sixth of the entire length : head large, rather 

 more than one-fourth : cranium fiat, a little concave between the eyes ;
