726 MR. F, 0. PICKARD CAMBRIDGE ON [June 16,” 
Iam unable to satisfy myself that P. scruposa, E. Sim., 9, op. 
cit., is identical with the species now before me. The description 
shows that they are undoubtedly closely allied; but of P. scruposa 
M. Simon says: “ Zarso 2 paris intus, prope apicem, aculeo unico 
instructis.” The tarsi of the second pair in P. papilligera have 
not this apical spine. He also says: ‘* Abdomen—aculeis bacilli- 
formis fulvis elevatis paucis, in series transversas parum regulariter 
ordinatis, munitum,” and makes no mention of the regular trans- 
verse rows of tubercles, each of which bears a bacilliform hair. I 
have therefore considered it more prudent, and less lable to cause 
subsequent confusion, to describe the present species as new. In 
any case the male is unknown to science, and would, on that account, 
merit a careful description. 
Note.—-Since writing the above another female, 13 mm. long, and 
a smaller one have come to hand from amongst my captures in the 
forest at Santarem. These specimens entirely bear out the dis- 
tinctions made between Paratropis and Anisaspis, while at the 
same time proving how inconstant are the number and position 
of spines and cusps, and how unreliable, as a character, is even 
the dentition of the mandibles. The eyes are closer together; the 
spinners four in number; the legs longer in proportion. The 
anterior tarsi have only a single row of cusps on either side, 
but the cusps are more numerous than in the female above de- 
scribed. The fang-groove is furnished with 16 teeth on the inside 
and 2 supplementary ones towards the apex, and 14 on the outer 
margin. The number of teeth is thus greater by 2 in each row than 
in the type female. The female described above must still be held 
as the type, although the other is a finer specimen, for both male 
and female were found side by side under the same piece of wood. 
One cannot be thoroughly satisfied concerning the differential 
characters of these Spiders until more material is available for 
careful comparison.

ANISASPOIDES GIGANTEA, n.sp. (Plate XXXIV. figs. 2 & 22.) 
9. Hab. Breves, Lower Amazons. 12°75 mm. long. Type in 
coll. Brit. Mus. Nat. Hist. 
Q .—Carapace a little longer than broad, purple-brown, finely 
granulate, and so closely encrusted with fine grit as to almost 
entirely obliterate all traces of the fine rufous hairs, of which there 
are three converging lines on the cephalic ridge, converging lines 
on the thoracic area, and a marginal line round the carapace. 
Central fovea deep, transverse, procurved. 
Abdomen encrusted with grit; bearing four rows of tubercles,
