what swollen, armed along outer edge and adjacent ventral sur- 

 face with stout curved spines pointing backward. Claw at outer 

 corner of this joint and those on terminal joint enlarged and 

 furnished along their margins with row of stout teeth. Color 

 as in female. Length 5 mm. ( C. B. Wilson.) 



Remarks. — This species was secured at Beach Haven in 1890 

 by Leidy. It was taken from the ocean sunfish (Mola mola) in 

 company with Orthagoriscicola and Cccrops. Leidy states that 

 his three examples, which were females, were 6 to 7 mm. long.

 genital segment, margins serrate. Abdomen on ventral surface 

 of genital segment, entirely concealed, lateral margins prolonged 

 into broad lamin?e similar to those of Cecrops. Egg-tules car-
