In America it has beeu found in the following localities: Eastern

 212, 213), Texas (Turner 215, 216), Minnesota (Herrick, 83), West

Not having met this species, I here giv^e Professor Herrick' s de- 

 scription. The figures are his also. 



'•Length equal to about twice the greatest height which lies just 

 behind the anterior third, anterior outline much higher than the pos- 

 terior, and evenly rounded, posterior margin acutely angular, lower 

 Outline slightly concave, upper margin twice angled; shell covered 

 with long curved spines; color yellowish, with eight lucid spots. An- 

 tennae (first antennte) slender, composed of seven segments, of which 

 all but the basal are short and sub -equal. >i« * =i< ^ * Antennules 

 (second antennae) with very short apical segment with two strong un- 

 equal claws and a minute seta, penultimate with two equal toothed 

 claws and a number of slender sette, third from end with five long and 

 several short setfe, preceding segment large, with three slender sette. 

 First foot five-jointed, second joint elongated, third and fourth equal, 

 each with a single short seta, apical segment small, with two set?e and 

 a long toothed gently curved claw; last foot moderately slender, termi- 

 nal joint with a small claw and two seta? at the apex and a lateral 

 Spine. Caudal stylets reduced to minute papilke bearing a slender 

 claw and a flexuous spine. The mouth parts bear the characters of 

 the genus Cypris. 



"In this species there is an aureole-like lucid zone about the an- 

 terior of the shell and a similar, but triangular, appendage behind. 



"The species may be regarded as forming a transition to Cypris 

 proper, as the form if not the size of the stylets is more as in that 

 genus." 



Habitat: Minnesota (Herrick, 86).
