Ntoholls and Baknes — A Neu' Terrestrial Isopod. 
rtcy-meiits three to five are -well developed. Tlie first five segments 
are siil)-e(|ual in lengtli, tlie anterior l)eing very sliglitly shorter; ! 
the last segment is large, slightly narrower than those jireecding, ; 
rounded jnisteriorly and witli very evident lateral portions. ^ 
I 
The njes are moderately devehpied, eomponiid, lateral in posh j 
tion. i ! 
The first natraan (PI. X, Pig 3) has three joints, the first 
broader and longer than the seeond; the third longer and narrower 
than the seeond, and hearing at and near the apex a number of i 
stout setae. ■ 
The second anfenna (PI. X, Pig. 4) has the first three joints of 
the peduiude more or less subuupial, the fourth is longer than the 
third, the fifth as hmg as the third and fourth eombiiied. The 
fiagelliini is a])])roximately equal in length to the last segment of 
tlie peduiude, and consists of three joints, the seeond being the 
shortest; tlie third longer than the first and tapering to the apex, 
which liears a tuft of setae. 
The upper lip is broader tlian long, and has the central portion i 
<-overed and fringed with short setae, | 
The riplit }nandible (Id. X, Pig. 6) has the outer cutting edge i 
strong and composed of three chitinous teeth ; tlie inner cutting | 
edge is less strongly developed and divided into two teeth; two 
]ienicils are present and the usual tuft of long plumose setae; the ■ 
ciliated lajipet is small. t 
The left mandible (PI. X, Pig. 5) has the outer cutting edge 
rei)i-esented by four strong chitinous teeth; the inner is distinctly 
defined and divided into a number of teeth; three penieils are pre- 
sent, two ii])])er and one lower; ciliated lappet prominent; setae 
in lowest group long and plumose. 
Both the niandihies have the iqqier distal edge fringed with 
setae. 
rite Jon'er lip is small, narrow, and has the inner and outer 
(distal) margins fringed with setae, also the surface near the 
iu;i(u- margin. 
Tlie first maxilla (Pig. 1, 1) has the external margin of the 
outer loJie slightly sinuous and fringed distaliy with a number of fine 
setae; the apex liears eight or nine setae, the four outer darker in 
i-olour and stronger than tlie inner. The inner lobe is more delicate 
and about half its width; the outer margin bears a number of fine 
ssdae distaliy; at the ajiex are the usual two plumose setae, which 
are short and stout.
