ocular area is equal to the length of the first metatarsus. Anterior 
row of eyes with its front margins practically in a straight line, its 
hind margins in a very slightly pro curved line : lateral eyes small, 
not quite so large as the medians : distance between median and 
lateral about equal to If times the diameter of the former, the medians 
about | of a diameter apart. Hind margins of posterior row of eyes 
in a strongly recurved line : medians a little smaller than the laterals. 
Distance of anterior lateral eye from anterior margin of carapace 
about equal to 1^ times the long diameter of the former. 
Legs. — Coxae without spinules or stout setae below. Patella IY 
without spines on any part of its surface and without spinules in its 
basal portion anteriorly, but with a superoanterior band of spiniform 
setae. The band along the anterior surface of the patella III is com- 
posed of stout spiniform setae, only one row being well developed 
and there are no spines. 
Pedipalp with about 45 spinules on the coxa inferiorly, extending 
the whole length of the segment. Labium with 23 teeth. Measure- 
ments. — Total length .18 mm., length of carapace T, breadth of cara- 
pace 6.2

of Adult Females. 
A. — Metatarsus IY without apical infero-posterior tuft of spiniform 
setae : femur II armed only with fine hairs inferiorly : patellae 
I and II without an oblique patch of peculiar stiff hairs arranged 
in one or several rows inferiorly.

0. P. Camb. 
B. — Metatarsus IY with an apical infero-posterior tuft of 3-5 spini- 
form setae regularly arranged in a transverse row : femur II 
with 1-2 rows of stout spiniform setae below : patellae I and 
II with an oblique patch of peculiar stiff hairs arranged in one 
or several rows inferiorly. f Moggridgea, 0. P. Camb. 
(a) Coxa 111 without a basal patch of spinules inferiorly , sometimes, 
however , with a group of fairly short setae. 
1 . Anterior of eyes (seen from above) with its front margin 
forming a straight or even very slightly recurved line, the 
laterals comparatively small, their area only about twice that 
of the posterior laterals. (Cape Peninsula.)

* The position of the four apparent species described by the Rev. 0. P. Cambridge from 
the Cape Peninsula (Annals South African Museum, 111, p. 144) under the generic name of 
Caedmon is not known to me. The genotype of Caedmon is Poecilimigas abrahami , but 
Mr. Cambridge distinguishes it from Moggcidgea only in the arrangement of the eyes : it 
is not clear therefore whether his Cape Peninsula species are referable to Poecilomigas or 
to Moggridgea as now distinguished. Three of those species are based on single adult male 
specimens : the species C. dubia, based on a female, has ocular characters distinct from 
those of Poeeilim ig as abrahami and may perhaps prove to belong to Moggridgea. 
The Durban species Moggridgea stauntoni Poc. (=P. gmlchrijyes Sim) is not specifically 
distinct from Poecilomigas abrahami O.P. Cambr. 
f Besides the South African speciesynly two others are known, viz., M. occidua E. Sint- 
from lie Principe, off the west coast of Africa, and M, whitei Poc., from the Nyik^,
