constant in position and number. The ocular characters are variable : generally, 
the length of the anterior lateral eyes is subequal to the intervening distance 
between anterolateral and anteromedian, but in the largest example slightly 
exceeds that distance, and sometimes is a trifle less. Length of metatarsus I 
subequal to, or in the largest specimen appreciably exceeding, the width of the 
ocular area. Distance between anterior and posterior lateral eyes decidedly 
less than the long diameter of the former in the largest example ; in most other 
examples they are subequal, but sometimes the anterior lateral is a little 
shorter than its distance from the posterior lateral. 
Measurement of largest female: length of carapace 10-3, breadth of cara- 
pace 9, length of first metatarsus 3-4, breadth of ocular area 3-2. 
This species will probably prove to be very limited in distribution. It is 
quite distinct from either of the two known to me from Grahamstown ( schon - 
landi Poc., and a species doubtfully identified as patersonae mihi). It seems 
well separated from the large species artifex Poc. which is known only from 
female specimens taken in the Bathurst district at Rokeby Park and at Sea 
View* near Kleinemond. It is different from the Peddie species, the males of 
which are very much smaller than that of tysoni. Possibly, these forms may 
ultimately be found to be linked together by intermediates : on the other hand, 
it is now certain that two related species may coexist in the same limited area, 
as is the case at Grahamstown, so that these various forms may really be stable 
entities. 
Evagrus cajfer Pocock var. australis Purcell (text fig. 10 a and b ). 
The species from Dunbrody described by Dr Purcell as Thelechoris australis 
now seems to be a variety of caffer. Since my former notes were written [A finals 
Durban Mus. vol. 1. p. 132), Mr Cruden has presented to the Albany Museum a 
series of males from Alicedale: so far as the sexual characters are concerned, 
these cannot be satisfactorily separated from caffer as found at Durban. The 
characters of the Alicedale males are as follows : 
Pedipalp short, when pressed forwards scarcely reaching the distal margin 
of patella I : bulb pyriform, passing gradually into the spine which tapers to a 
point at the apex where it is slightly curved, the basal part of the spine being 
broadly curved : tarsus short and without spines : tibia longer than the patella, 
expanded below and beset on all the surfaces with long curved stout bristles 
or setiform spines, except on each side in the proximal half and inferiorly on 
the outer side, three of the inferior spines on the inner side being a little 
stouter than the rest: long spiniform setae also occur on the upper surface of 
the patella, and on the distal edge inferiorly, and others on the posteroinferior 
edge of the femur, each arising from a minute tubercle. 
Tibia II on the anteroinferior edge with a very strong, forwardly projecting, 
compressed, process, situated about two-fifths of the length of the segment 
from its distal margin, the process bearing two, three, four or five black, sharp 
pointed, claw-like, tubercles. 
Metatarsus II with a fairly strong obtuse projection, tipped with a spine, 
on the ventral surface at a point about one-third of the length of the segment 
from its base: this segment measured on the mid-dorsal line is much longer 
than tibia II. Tibiae and metatarsi of all the legs armed inferiorly and at the 
sides with long spines. Tarsi spined at the sides and thinly scopulate below. 
Dorsal surface of abdomen with numerous long, outstanding, bristly setae, 
as well as golden hairs, and similar stout setae occur on the legs.
