Phalangium, Linneus, Syst. Nat. ed. x. p. 618 (1758). 
Type P. opilio, Linn. Europe. 
Anterior margin of the clypeus not armed with conical spurs beneath. Basal segment of mandibles without 
spur or tooth. Eye-tumulus simple or with cusps. Palpus in the male sex with cuspules beneath the 
tarsus ; patella never developed to form a spur. Palpal claw simple or pectinate. Coxal maxillary lobe 
with two conical spurs. Tibia ii. without false-articulations. Legs i. and iii. stouter than ii. and iv., 
the former being the most slender; terminal tarsal claws single, simple.

1. Phalangium armigerum, sp.n. (Tab. LIV. figg. 8, 8a, 3; 9,94, 2.) 
Type 3d, gynetype 2, in coll. Godman & Salvin. Total length, 3, 10, femur of leg ii, 12 millim.; 
@, body 12, femur of leg ii. 11 millim. 
g. Clypeus with a central pair of minute spines and a lateral one on each side. Eyes two, one on each side 
of a low globular tubercle, which is transversely truncate in front. Posterior segments of the prosoma 
each with a transverse row of minute spines. Segments 1-4 of the opisthosoma with a pair of larger 
central spines, transversely situated, besides a transverse row of more minute spiniform tubercles on each 
of the nine segments, becoming, however, almost obsolete on the posterior four segments, though more 
conspicuous laterally. 
Mandibles small, basal portion of apical segment as long again as the digits. Movable digit strongly hooked 
at its apex, each digit bearing a large triangular tooth towards the base, followed towards the apex by a 
row of serrations. 
Palpi: femur set below with scattered spines; tibia with a band of closely-grouped spines beneath ; tarsus 
with a double row of very closely situated spines, extending from the base almost to the apex, the 
segment terminating in a stout, simple, curved claw. Leg i. developed to form aclasper; all the segments, 
except the protarsus and tarsus, more or less numerously spined ; tibia incrassate beneath in the basal 
half, bearing on the outer margin a conspicuous series of about twenty black-pointed spines, the inner
