210 ARANEIDEA. 
LIGER*, gen. nov. (fam. Theridiide). 
Cephalothorax much longer than broad, oval; lateral marginal impressions at the caput scarcely perceptible 
and normal lateral indentation slight; thoracic indentation very large, circular, dish-like. Upper 
convexity moderate. Caput scarcely higher than the thorax. Ocular area sloping forwards. Clypeus 
transversely impressed at the middle, and prominent at the lower margin ; its height greatly exceeds half 
that of the facial space. 
Eyes rather small, subequal, widely placed, across the whole width of the caput; the fore-centrals form a 
large quadrangle a little broader than long. The lateral pairs are largest, and each is seated on a 
strong tubercle. The posterior row is straight or very nearly so. The fore-central pair are on a slight 
prominence, 
Legs slender, not very long, 1, 2, 4, 3, furnished with hairs, many of which are long and bristle-like, and with 
a long bristle from each of the genue. 
Falces tolerably strong, straight. 
Mawille moderately long, strong, broad, inclined to the labium, which is broader than high, and well rounded 
at the apex, though not of a semicircular form. 
Sternum subtriangular, somewhat heart-shaped, longer than broad, and broadly truncated at the posterior 
extremity, the coxe of the fourth pair of legs being separated by an interval equal to their own length. 
Abdomen short, globular, joined to the thorax by a short but distinct pedicle, which is somewhat covered by 
the projecting edge of the hinder part of the thorax. 
Liger incomta, sp. n. 
Adult male, length 1 line. 
Cephalothoraax yellowish-brown, with a slender black longitudinal line from the thoracic indentation backwards. 
Normal grooves indicated by converging darker lines. 
Legs and palpi pale yellow ; the coxal joints have their undersides prominent in a longitudinal ridge-like form. 
Falces, mawille, labiwm, and sternum slightly tinged with yellow-brown. The falces have a strong, abrupt 
prominence at their base in front, but this is probably only a sexual character. 
Palpi short; cubital joint short, bent, claviform ; radial joint longer and stronger than the cubital, its fore 
extremity spreading over the base of the digital joint and closely fitting (its point of contact is not easy 
to see at first sight); digital joint rather large, oval; the palpal organs compact, and, among other 
corneous processes, a strongish curved tapering spine springs from a large process at the fore end, and 
curving backwards crosses over about the middle of the palpal organs to their inner side. 
Sternum strongly convex and with somewhat ridge-like but not strong prominences opposite to the insertion 
of the legs. 
Abdomen yellowish, thinly clothed with hairs. Spinners short, compact. 
Hab. GuatrEMaa, between Petet and Chicoyoito (Sarg). 
ACHZA, Cambridge. 
Acheza crocea, sp. n. 
Adult male, length rather less than 1 line. 
This spider resembles some species of the genus Lascola, Simon, more nearly than the typical species 
of Achea, A. insignis, Cambr., owing to the rather more produced and prominent fore extremity of the 
caput and higher clypeus. 
Cephalothorax dull orange-yellow, with a few long, erect, slender, bristly hairs on the upperside. The clypeus 
is strongly impressed across the middle, and prominent at the lower margin; its height greatly exceeds 
half that of the facial space. 
Eyes normal ; looked at from above and slightly behind, the posterior row is straight or very nearly so. The
