1916. BraDe AND BiRKS— /m/^ Chilopcds. [25 
The only exception which it has fallen to my lot to examine consisted 
in two spines on the inferior surface of the 3rd joint, 
Coxal pores small, circular ; I generally found the following dispositions : 
I, 2, 2, 2, or 2, 2, 3, 2 ; exceptionally, on one individual : 2, 3, 3, 3 and 
on another i, 2, 2 3, 2. 
The external genital organs of the female are armed with 24-2 spines, 
fairly robust and long, especially the external pair, which is at times a 
little curved outwards. 
Claw broad, divided into three parts, of which the two internal ones 
are much more developed than the third, which is often reduced to a sharp 
spine.i 
It has happened most unfortunately that of the three 
specimens from Ireland reported by Dr. Brolemann to be 
certainly Lithohius Dtihoscqui only one has been available 
for the present study. Tubes 155 (Dublin 181) and 158 
were smashed in the post ; leaving only 159, one specimen, 
a male, for the purposes of the present paper. On it— 
an apparently abnormal specimen (at any rate as far as the 
ocelli were concerned) and at the same time a very much 
damaged individual — the following notes are made : — 
Body convex dorsally, spindle-shaped and constricted 
behind the head, widest about the 7th and 8th segments, 
shiny, the surface very finely granulated. 
Length of body, 6.9mm. 
Width of the 8th segment, o.89nmi. 
Cephalic shield subcordiform, marginated behind. 
24-2 teeth on the coxae of the maxillipedes. The coxae 
arc not separated between the teeth by a very deep cleft. 
There is a marked median sulcus between the lateral borders 
of the coxae. All the dorsal shields are more or less mar- 
ginated, and all are rounded or rectangularly bordered 
posteriorly. (Antennae and ist pair of limbs broken 
away). 
The 14th and 15th pairs of limbs are incrassate ; 
, 0,0,1,0,0. ^ 0,0,1,0,0 , , , 
Armatures : 14th, — 15th, double claw. 
^ 0,1,1,1,0. ^ 0,1,1,1,0. 
The ocelli did not agree in this specimen with Dr. Brole- 
mann's original description, but were arranged thus : —
