After tliese preliminary definitions I will now des^cribe in detail the various 

 species of Sparganophilus examined by me. 



Sparganophilus Smithi n. sp. 

 Figs 120-122, 124, 129-39. 



Habitat. This species is very abundant in a small lake or pond known as 

 Lagnna Puerca and situated between Lake Merced and Golden Gate Park at San 

 Francisco. Adult form in June to October, more frequent in the latter month. It 

 occurs at or near, above and below the water's edge, the earth being thrown up in 

 abundance and in heaps. I have already referred to nonpresence of this species 

 some ten years ago in the al)ove locality. 



EXTERIOR CHARACTERS. 



Color. A brownish flesh with violet reflex, but much less so than Sp. Benhami 

 or Sp. guatemalensis. In alcohol this s|)ecies becomes much paler than either of the 

 two just referred to, almost pure white, looses its irridescence entirely. In formalin 

 the color is pale, the irridescence very faint, strongest on the clitellum, and hardly 

 perceptible on any other part of the body. 



Length varies some, but generally reaches in fully grown and largest speci-
