314 GEOL. AND NAT. HIST. SURVEY OF MINNESOTA. 
In America it has been found in the following localities: Eastern 
United States (Herrick, 86), Georgia (Turner, 215, 216), Ohio (Turner, 
212, 213), Texas (Turner 215, 216), Minnesota (Herrick, 83), West 
Virginia (Turner, 215). 
The Texas specimens were collected by Mr. A. B. Whitby.

Not having met this species, I here give 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- 
tenne (first antennz) slender, composed of seven segments, of which 
all but the basal are short and sub-equal. * * * * * Antennules 
(second antenne) 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 setie, third from end with five long and 
several short sets, preceding segment large, with three slender sete. 
First foot five-jointed, second joint elongated, third and fourth equal, 
each with a single short seta, apical segment small, with two sete and 
a long toothed gently curved claw; last foot moderately slender, termi- 
nal joint with a small claw and two setx at the apex and a lateral 
Spine. Caudal stylets reduced to minute papilla bearing a slender 
claw and a flexuous spine. The mouth parts bear the characters of 
the genus Cypris. 
‘‘TIn 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).
