4.54 ONISCIDA. 
ISOPODA. ONISCID. 
NORMALLA. 
Genus—PHILOUGRIA. (Kinahan.) 
ITEA.* (Koch.) 
Generic character. Ovate, sub-depressed. Cephalon without 
frontal or lateral lobes. Outer antenne nine or ten-jointed, 
with the second joint cylindrical ; terminal joints subulated. 
Coxee of first and sixth rings of pleon obsolete. Uropoda 
entirely exserted; basal portion trigonate. Outer ramus 
elongate, pointed, and exserted obliquely. Inner narrow, 
extending beyond the middle of outer, pointed. 
Tus genus was first proposed by Zaddach, and subse- 
quently adopted by Koch under the name of Jtea—a 
name employed by Linnzeus for a well-known genus of 
plants. Its description also was not sufficiently precise ; 
whence Professor Kinahan was at first induced to con- 
sider the native species as undescribed, both generically 
and specifically. For both these reasons we consider 
ourselves warranted in adopting the generic name pro- 
posed by the lamented Irish naturalist. 
The species are of comparatively small size, with the 
body smooth and shining. The limbs are armed with 
strong spines, generally arising from small conical 
tubercles. The structure of the front part of the head 
is nearly similar to that of Philoscia, but the lateral 
ridges around the insertion of the external antennez are 
somewhat more strongly marked. The outer antennz 
are entirely exposed at the base. The five basal joints 
constituting the peduncle are robust, spined, and gra-
