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

 face with stont 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

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.

 wider than long, much narrowed anteriorly, posterior edge 

 scarcely reentrant. Posterior carapace lobes very broad and 

 evenly rounded. Eyes invisible. Groovings on dorsal surface in-

 genital segment, margins serrate. Abdomen on ventral surface 

 of genital segment, entirely concealed, lateral miargins prolonged 

 into broad laminae similar to those of Cecrops. Egg-tules car- 

 ried between these laminae and dorsal plates of genital segment as 

 in Cecrops, irregularly coiled and many times bod^y length. First 

 antenuce three-jointed. Second pair stout, uncinate. Maxillae 

 much smaller than in Cecrops and mouth-tube about same. Sec- 

 ond maxillipeds stout, with large terminal claw. All swimming-
