New Arachnida. 27 



The hole is much more slanting, and although cylindrical or nearly 

 so in the deeper parts, it widens funnel-like towards the opening on 

 each side and also at the hinge, but not on the side opposite to the 

 hinge (pi. I., fig. 3). The hole is, therefore, oval in section near the 

 opening, with the hinge-side flattened. 



The lid is D-shaped in outline (pi. I., fig. 4), being strongly 

 truncated at the hinge-margin. The hinge is very wide, exceeding 

 in width the cylindrical part of the hole. In other respects the lid 

 resembles that of Stasimopus schreineri, described above. The edge 

 is strongly bevelled, passing over quite gradually into the lower 

 surface, on which there is no circle of conspicuous pits. A small 

 group of these pits are, however, sometimes present in the centre." 



The lids and loosened tubes of a number of other specimens were 

 also sent by Mr. Schreiner, having been removed from the surround- 

 ing earth. In such cases the bevelling at the edge of the under 

 surface is frequently quite absent, owing to the flattening out of the 

 lid by pressure during packing. Such lids have the false appearance 

 of being perfectly flat on the under surface. 



ANCYLOTRYPA PUSILLA, n. sp. 



Type. 1 $ (No. 9455) from Hanover (October). 



$ . Colour. Carapace pale yellowish, not black-bordered but 



* The nests of the 3 large trap-door-building spiders at Hanover may be dis- 

 tinguished as follows : 



a. Lid D-shaped, the hinge very wide, wider than the cylindrical part of the 

 hole ; no circle of conspicuous pits below (hole more strongly slanting, 

 the upper part oval in section, with one side flattened). 



Gorgyrella schreineri, n. sp. 



h. Lid nearly or quite circular, the hinge narrower than the cylindrical part of 

 the hole, which is only slightly slanting. 



a 1 . Lid moderately thick, strongly bevelled at the edge, with rounded lower 

 edge ; under side without circle of conspicuous pits. 



Stasimopus schrcineri, n. sp. 



b 1 . Lid very thick, less strongly or scarcely at all bevelled at the edge, the 

 lower edge more angular ; under side with a circle of very conspicuous 



pits Stasimopus iinispinosw, n. sp. 



I may mention here an interesting observation in connection with old trap-door 

 nests. In November, 1897, Mr. Isaac Meiring discovered 3 Geckos in a closed 

 trap-door nest of a species of Stasimopus common round Worcester, Cape Colony. 

 The spider was, of course, no longer in the nest. In February, 1902, Mr. Schreiner 

 found a number of old trap-door nests at Hanover inhabited by the same species of 

 Gecko, which has been identified by Mr. W. L. Sclater as Pachydactylns mari- 

 quenxis,' Smith. One such nest sent to us was that of Gorgyrella schreineri, n. sp., 

 and in it one young and two adult Geckos had been found. Mr. Schreiner men- 

 tions that the doors of the nests inhabited by Geckos remain in working order, and 

 are kept closed as usual.
