slightly downwards, assumes nearly a straight course, which 

 is continued to the base of the caudal rays. 



The pectoral, ventral and anal fins are reddish. The dor- 

 sal and caudal are of a dark brown. 



The Dorsal fin arises back of the middle of the body, and is 

 rather longer than high. 



The Pectorals commence just behind the branchial opening ; 

 their height to their length as 2 to 1. 



The Ventrals arise on a line opposite the middle of the dor- 

 sal fin, and are in length to their height as 1 to 3. 



The Anal fin, which is rather rounded than pointed, is in 

 length to its height as 1 to 2. The anus is at the origin of the 

 anal fin. 



The Caudal fin is deeply forked ; and its depth at extremity 

 is to its depth at its base as 2 to 1. 



The fin rays are as follows : D. 13 ; P. 18 ; V. 10 ; A. 9 ;

Of this species, described by Le Sueur from specimens ob- 

 tained in Pennsylvania, I have seen but two individuals, which 

 were taken at Watertown with the preceding species. I am in- 

 formed it is not an uncommon fish in the ponds of various 

 parts of this State and New Hampshire, and that it is called, 

 very incorrectly however, the '^^ BarhelJ^ 



A specimen, fourteen inches in length, presents the follow- 

 ing appearances. Greatest depth rather less than one and a 

 half inches ; width across the body from the commencement of 

 the dorsal fin about three inches. This species is readily dis- 

 tinguished from the C. '' Bostoniensis,^^ our most common 

 sucker, by its being less elongated, and deeper ; and by the 

 gibbosity of the nape of the neck ; and from all other species, by 

 the tubercles on its snout. Color above, dark brown ; sides yel- 

 lowish ; beneath white. Scales large, with golden reflections, 

 and distinct radii. Length of the head, two inches fom- lines ;
