736 MR. F, 0. PICKARD CAMBRIDGE ON [June 16, 
Cova of pedipalp three times its breadth, not produced at 
anterior angle; bearing on the inner basal angle three sharp black 
cusps set in a curving row. 
Legs 4,1, 2,3, clothed with fine rufous hairs, black curving 
bristles, and black spines. Tarsi i. and ii. with two claws and a 
claw-tuft ; claw armed with a minute denticle rather before the 
middle, beneath ; scopulate. Tarsi ili. and iy. with two claws and 
a claw-tuft, the claws bearing no denticle; very slightly clothed 
beneath with scattered scopuliform hairs. Protarsi i. and ii. with 
slight scopula at apex and two stout spines, one apical, the other 
basal, beneath ; iii. and iv. with numerous spines. Tibiai. bearing 
at its apex on the inner side, beneath, a pair of stout curved spines 
set in juxtaposition to each other, with five ordinary spines, 
2—1—=3 beneath, and one on the inner side. Tibia iii. and iv. 
with numerous spines. Femora of all four pairs with five or six 
spines above. 
Pedipalp. Femur with a few spines at apex above. Tibia 
fringed on either side beneath with long hair, and six spines on 
the inner side, two on the outer. Tarsus short, half the length of 
tibia. Bulb short, pyriform, transverse, its stylum very short, 
curved, directed outwards and backwards. 
Comparative measurements in millimetres.— g. Carap. 6°5 long., 
5°5 lat. Abd. 5°5 long., 3°5 lat. Ceph. area 4 long. Stern. 3°25 
long., 2°5 lat. Coxa of pedipalp 2°5 long., 1:25 lat. Pedes, long. 
i. 25—ii. 23—iii. 20—iv. 30. Artl. i. long. 3°-25—1-25—6:5—3— 
55—4—3, Artl. iv. long. 3—1—7-5—2—6—8:5—2'5, Postr. 
mam. long. 3°5; artl. 1-6—1—*5. Antr. mam. °75. 
My attention was called to a fine specimen, an adult male, of 
this species by Mr. E. E. Austen when collecting in the neighbour- 
hood of Manaos, Amazonas, in February 1896, and I have great 
pleasure in connecting his name with the species. The generic 
characters which distinguish Homeoplacis from Barychelus are 
well marked. Cephalic fovea procurved; rastellum at apex of 
mandible consisting of five separate teeth ; coxa of pedipalp armed 
near the base with only a few (3-4) small cusps ; ocular tumulus 
narrower in front. 
M. Simon apparently does not know the male of the species he 
has made the type of his genus, so that no mention is made of the 
spines at the apex of the tibiz of the first pair of legs. 
Species described.—H. pentodon, Sim. op. cit. p. 275. 
It is possible that the Spider described above may be the male 
of the one described by Simon: but it is not easy to identify a 
specimen of this sex from a description of the female. He says of 
it—‘* Parte cephalica vittis duabus;” of H. austeni one would 
rather say—* Parte cephalica lineis tribus;” and again he says: 
“ parte thoracica lineis radiantibus, lineaque marginali obscuriori- 
bus notatis” ; whereas in my specimen there are no radiating lines 
and no marginal dark line.
