Rey. A. M. Norman on new British Species of Ostracoda. 51 
cies in medio levis, undique margine elevato circumdata, proces- 
sibusque linguiformibus, inferne et  postice maxime conspicuis 
fimbriata. Color albescens. Long. vix 34; unc. 
Habitat fretum, qui Firth of Clyde vocatur, in Scotia occidentali. 
Carapace oblong; the dorsal margin concave; ventral margin 
a little convex, extending beyond the dorsal margin at both ex- 
tremities; anterior and posterior margins obliquely truncate. 
Surface of valves smooth in the middle, but surrounded by a 
raised rim, from whence proceed at various parts, but more 
especially on the inferior and posterior margins, large flattened. 
linguiform processes. The extremities of the dorsal margin are 
raised so as to form rounded protuberances. My specimen is 
whitish in colour, but has a bluish tinge, and may perhaps be 
bleached. Length not quite ., inch. 
Found by Mr. T. R. Jones at Arran, and by myself among 
sand dredged off the Isle of Cumbrae, both localities being in 
the Firth of Clyde. 
I have had no opportunity of seeing Roemer’s description and 
figure; and I adopt the name of Cythereis fimbriata from the 
specimen in the British Museum so named by Mr. T, R. Jones,
