Liocra7iu7n alhopU7ictat7t77i, sp. n. (Fig. 8). 
Cephalothorax deep jet black. Skin bare, rough, and covered with pimples. 
Cephalic part smooth and shiny. A line of white pinnated scales or feathers 
extending longitudinally from between the hinder middle eyes to the beginning of 
the hinder slope. Similar white scaly feathers round the hinder margin of the 
breast part and on each side round the margin of the cephalic part. Abdomen 
deep black above, a blotchy, pale, curved streak round the anterior margin ; a few 
long black bristles on the clypeus below the eyes. Skin shagreeny, two white 
patches about the middle of the back and two more half-way between the middle 
and the anterior margin, composed of similar feathery flakes as those on the 
cephalothorax ; under surface black-brown, with thin down-lying black hairs. Legs 
and palpi deep to paler chocolate-brown, smooth and shiny; tarsi and metatarsi 
paler still, the whole of these and of the under surface of other joints more or less 
thickly covei’ed with long erect brown hairs. Sternum black-brown, with thin 
erect pale brown hairs. Mandibles black-brown, smooth and shiny, inner front 
edge much paler, with a few upstanding black hairs on the upper part. Lip and 
maxillie black-brown, the upper portion of the former and the inner slope of the 
latter pale colour; hair fringe pale orange. Epigyne bright reddish-brown; 
mammillie black-brown. 
Cephalothorax longer than the patella and tibia of the first pair, mm. longer 
than broad ; strongly arched transversely, breast part sloping steeply from the 
middle point to the posterior margin; in front square and not much narrower than 
the broadest part between pairs two and three. A few upstanding thin black 
hairs on the upper surface and the hind slope of the breast part, but most remark¬ 
able for the down-lying white feathery scales.
