and Boleichthys, with an arched and incomplete lateral line. The scales are larger 
than in related species and present on the opercles, and the dorsal fins are well 
separated, two rows of scales crossing the back between the fins. 
The above description is based upon four specimens, 37, 39, 51, and 56 mm. in 
length, respectively, taken in March, 1918, in a small, sluggish creek on the Sanitary 
Dairy Farm near Augusta. The largest one, a female, contained well-developed ova. 
These specimens appear to represent an undescribed form, which is probably not 
common. The specimen 51 mm. in length, United States National Museum No. 
82633, is designated as the type. This darter is named for Surg. L. D. Fricks, of 
the United States Public Health Service, in charge of field investigations relative 
to malaria control, under whose directions the investigations in 1921 and 1922 
were conducted. 
37. Boleichthys fusiformis (Girard). Fusiform Darter. 
This is the only darter inhabiting the ponds and swamps in the vicinity, and 
it is found both on muddy bottom and among vegetation. It was unknown to 
the local fishermen who saw the specimens. A female taken on September 26 
contained large roe.
