inferiorly. The tergites, except the last one, have extensive smooth areas^- 
on their anterior portions. Basal pectinal tooth not enlarged, though its. 
apex is broader and more rounded than in the adjacent teeth. The trunk is 
dark brown without any pale markings on the tergites. This form 
resembles that described by me from Kim berley under the name oi flavidus^. 
but is darker and the caudal segments less strongly granulated inferiorly. 
The typical form of triangulifer, with enlarged basal pectinal tooth in the 
female, also occurs in the same district, having been taken recently at Town 
Kloof, Eustenburg (Transvaal Museum). 
The V-shaped markings on the tergites, which seem so characteristic in 
preserved specimens of the common form of the species, are scarcely notice- 
able in life, and are not found at all in the newly born young which are 
coloured as follows : Tergites brown with a broad yellow mesial stripe ; 
carapace pale brown with some variegations ; appendages and tail yellow, 
except the brachium, hand (but not the fingers), fifth caudal segment, and 
vesicle, which are dark brown. 
Uroplectes lineatus, Koch. 
Papagaaiberg, near Stellenbosch (C. S. G-robbelaar) ; G-eorge (M. 
Wilman) . 
The former is a strongly infuscated specimen with no continuous stripes 
on the abdomen, the stripes of each tergite being merely represented by pos- 
teriorly situated yellow blotches. The stripes became quite conspicuous, 
after immersion in spirits for several days.

The Shiloh specimens, an adult male and adult female, have the following 
characters : Seventeen pectinal teeth. Basal pectinal tooth of the female a 
trifle shorter than the rest, but not appreciably broader, or only slightly so 
in its basal portion. Hands similar in the two sexes. Tail of male longer
