1896.] AND LITTLE-KNOWN SPIDERS. 1009 
FRIvLA WALLACH, sp.n. (Plate LI. fig. 2.) 
Adult female, length 34 lines; length of abdomen 23 lines ; 
width of abdomen slightly less than the length; total width to 
extremity of the lateral projections very nearly 8 lines. 
The whole of the Spider is of a dark rich reddish-yellow-brown 
colour, the sigilliform markings on the abdomen being a little 
darker than the rest. It is, however, quite possible that in life 
there might be other tints and colours now lost by age and 
desiccation. 
Although an unmistakably Gasteracanthid Spider, it seems to 
me impossible to include this remarkable form in any genus as yet 
characterized. 
Found by Dr. A. R. Wallace at Sarawak many years ago, and 
obtained from the collection of the late Mr. Wilson Saunders. 
Tt is only lately that I have been able to ascertain (from 
Dr. Wallace) that he was the captor of this Spider, and in the 
locality mentioned. 
Lagpacus, Cambr. 
LABDACUS MONASTOIDES, Cambr. (Plate LII. fig. 3.) 
The female of this Spider (described and figured, P. Z. S. 1878, 
p- 118, pl. xii. fig. 3) was from Rio Grande, Brazil. The male 
now described resembles the female in general characters, colours, 
and markings. The length is 53 lines, that of the abdomen 
being 33 lines. 
Cephalothorax longer than broad, oval, truncated at each end ; 
rather flattened above; profile-line to the posterior eyes level, 
excepting a slight depression at the thoracic junction; height of 
clypeus less than half the diameter of one of the fore-central eyes ; 
lateral marginal impressions at the caput moderate. Colour 
brownish yellow, with a black marginal line and dusky converging 
bars. 
Eyes greatly unequal in size, in three widely separated groups, on 
black tubercular eminences. The lateral pairs with the hind- 
central pair form a transverse curved line, whose convexity is 
directed forwards. The hind-lateral eye is the largest and seated 
on the outside of a strong hemispherical prominence, at nearly an 
eye’s diameter from the fore-lateral, which is the smallest and 
placed in front of the same eminence; the hind-centrals are 
nearly, if not quite, as large as the hind-laterals, they are rather 
more than a diameter’s distance apart. The four centrals form a 
quadrilateral figure, whose length is greater than its breadth, and 
its anterior side much the shortest. 
Legs long, moderately strong, 1, 2, 4,3; colour yellow; armed 
with spines, of which those beneath the tibie and metatarsi of the 
first and second pairs are long, strong, and placed in a longitudinal 
series of 8 or 9 pairs beneath the tibiz, and 7 or 8 beneath the 
metatarsi; tarsal claws 3, springing from a small claw-joint.
