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. S.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 unhke some 

 examples of P. affinis, but is at once distinguishable by its shorteued 

 and straightened bill. 



In revising the Dendrocolaptidse for the 15th volume of the British 

 Museum Catalogue I have found it necessary to use two new generic 

 forms. These are : — 



(1) LiMNOPHYES {Xljivr) palus et ^{/w (jigno), for Limnornis 

 curvirostris, Gould (Zool. Voy. Beagle, iii. p. 81), a form allied to 

 Limnornis, but differing in its curved bill ; and 



(2) Hylexetastes (vXj? silva et e^era(7ri)s investigate), for 

 Bendrocolaptes perroti, Lafr., which is allied to Dendrexetastes, 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, 

 Pachylomeriis 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 (Eresidce) 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, 

 pi. X.) from Uitenhage, South Africa, under the name of Mogg- 

 ridgea dyeri. Subsequently in 1887 a note was communicated to
