The fishes thus far captured in this region belong to 32 

 families of which that most numerously represented by 

 species is the minnow family with 24. There are 12 species 

 of sunfishes and basses, 8 of perches and darters, 7 of cat- 

 fishes and 5 each of the sucker, and shad families. Twenty 

 families are represented by only one species each. Of the 

 species of fishes that have been described from this region 

 at least 3 are now recognized as good species and one as a 

 variety; these are two minnows, Notropis hudsonius amarm 

 Girard, Notropis analostanus Girard, a silver-side, Menidia 

 beryllina Cope, and a darter Boleosoma effulgens Girard.

BATRACHIANS AND REPTILES. 



Though these two groups are not closely related, custom-

 the region of the District of Columbia. The batrachians 

 inhabiting this vicinity comprise 14 species of salamanders, 

 3 toads, and 10 frogs, and the reptiles include 4 lizards, 21
