After these preliminary definitions I will now describe 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 
Laguna Puerea 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 above locality. 
EXTERIOR CHARACTERS. 
Color. A brownish flesh with violet reflex, but much less so than Sp. Benham 
or Sp. guatemalensis. In alcohol this species 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-
