34 REV. O. P. CAMBRIDGE ON NEW ARANEIDEA. _ [Feb. 5, 
back, spotted with well-marked yellowish shaft-spots, which are short 
and triangular on the head, and long and thin on the neck; the shaft- 
spots on the head are slightly margined with blackish : beneath earthy 
brown, densely spotted with elongated ochraceous shaft-spots, which 
are distinctly edged with blackish ; flanks and crissum less marked ; 
chin and middle of throat pale ochraceous, unspotted ; bill very short, 
slightly incurved, pale brown; feet dark. Whole length 8-0, wing 
4°0, tail 3°8, bill from gape 0°9. 
Hab. 8.E. Brazil. 
Mus. S.-G. 
The single specimen of this species, which was purchased of a 
dealer, but is of apparently “Brazilian” make, is not unlike some 
examples of P. affinis, but is at once distinguishable by its shortened 
and straightened bill. 
In revising the Dendrocolaptide: for the 15th volume of the British 
Museum Catalogue I have found it necessary to use two new generic 
forms. These are :— 
(1) Limnoruyes (Aiuyn palus et iw gigno), for Limnornis 
curvirostris, Gould (Zool. Voy. Beagle, iii. p. 81), a form allied to 
Limnornis, but differing in its curved bill; and 
(2) Hytexerasres (An silva et éZeraorijs investigator), for 
Dendrocolaptes perroti, Lafr., which is allied to Dendrewetastes, but 
differs in its much stronger and stouter bill.

The Spiders described in the present paper are from the widely 
separated localities of Burmah, South Africa, and Australia. The 
principal interest attaching to two of them (from South Africa) 
arises from their being represented, at this moment, by examples 
living in this Society’s Insect-house. One of these two spiders, 
Pachylomerus natalensis, has been there for the last twelve months 
along with its fine trapdoor nest. The other, Stegodyphus gregarius, 
has only lately been received there, and is also interesting as 
being the first, I believe, of this group (Hreside) whose habits 
are known to be gregarious: the nest is of large size, and contains 
from 100 to 150 inhabitants of both sexes and various ages. Some 
few of these had died on the passage from Durban, and from these 
the subjoined description has been prepared. Another of the spiders 
described is interesting as being the second known species of Tree 
Trapdoor Spiders. The first species was described and figured by 
myself several years ago (Ann. & Mag. Nat. Hist. xvi. (4) p. 319, 
pl. x.) from Uitenhage, South Africa, under the name of Mogg- 
ridgea dyeri. Subsequently in 1887 a note was communicated to
