But a single specimen of this species is known 5 it is, however, totally 

 distinct from all the rest 5 its relations are chiefly with gyrinus.

I have examined specimens of this species from Orange, Eockland, 

 and Chemung Counties, New York. It resembles the next, but is in 

 every way slenderer and weaker.

Comparison of eastern and western specimens referred to gyrinus show 

 surprising differences of form, and as these differences appear to be con- 

 stant in a great number of specimens examined from widely separated 

 localities, I have decided to separate the western form as a distinct 

 species. 



The eastera form, or gyrinus, has the head shorter and every way 

 smaller, and the body proper more elongate, more compressed, almost 

 ribbon-shaped, and the si)ines rather weaker. The coloration is the
