 placed innumerable minute leeches in the same tank, and these

Body slender. Head moderate in size. Second antennae or 

 male claspers with basal joint very large, thick, somewliat curved. 

 Second joint very long, slender, curved inward, with sharp basal 

 spur. Two remarkably long- large frontal appendages arise be- 

 tween base of second antennas, their length about twice that of 

 second antennae, much twisted and coiled, and variously lobed 

 and spinulated. Eleven pairs of natatory feet Basal lobe or 

 endite long, with edge .regularly curved, and second with an 

 outer subdivision about one-fourth as broad as first. Each pair 

 of feet paler, with rather long fringe of delicate hair-like setse. 

 Second to fourth endites small, each with three or four long 

 minutely spinulated setae. Fifth endite of usual size, but rather 

 square, much as in Buhranchipiis , with tendency in lower outer 

 angle to be somewhat produced so as to be subtriangular in out- 

 line. vSixth endite unusually long, narrow, almost lanceolate, 

 with long setae in third pair of feet, or small, narrow, and 

 abruptly rounded in first pair. In tenth pair narrow and rounded 

 at tip. Flabellum and gills much as in Buhranchipus. Male 

 genital apparatus short, small, deeply cleft, formed into two 

 slender curved portions, each with its cirrus. Caudal appendages 

 long and broad, much more so than in Enhranchipiis. Second 

 antennae in female with mucronate spur on tip larger and longer
