Ncio South African Spiders. 71 



and provided with a pair of conspicuous pits in the centre, which 

 are always placed as in fig. IB. 



The hole descends at a considerable incline in the upper part and 

 reaches a depth of 4-4J inches (10-11^ cm.). At the opening the 

 tube-lining is suddenly bent outwards to form a depressed funnel- 

 shaped, spreading rim about 2-3 mm. in width all round, against 

 which the lid closes. * 



It is characteristic of both J\I. mordax n. sp. and M. terricola 

 E. Sim., that the lid is not placed with its upper surface flush with 

 the ground but is distinctly raised above it, just as if it were a 

 detached piece lying loose upon the veld. This circumstance makes 

 it very difficult to distinguish these lids in the case of M. mordax 

 from the many small flat pieces of earth which have become 

 loosened from the cracked surface of the ground, so that one 

 has generally to lift the piece before one can be certain whether 

 it covers a nest or not. 



2. MOGGKIDGEA LEIPOLDTI 11. Sp. 



Type. I 2 (No. 3619) found by Mr. C. L. Leipoldt on the road 

 from Clanwilliam to Van Ehyns Dorp, Cape Colony, in December, 

 1897. 



Closely resembling the foregoing. 



2 . Abdomen pale yellowish, the hair-bearing tubercles black. 



Carapace longer than the tibia, metatarsus, and tarsus of first leg, 

 but shorter than the tibia and metatarsus of fourth leg. Fovea 

 without the median groove. Ocular area with its width very 

 slightly less than the length of the first metatarsus ; posterior 

 median eyes narrow elongate, twice as long as the small lateral 

 eyes. 



Coxa III with a basal patch of 26-27 stout short spinules, the 

 other coxae muticous. 



Labium with 23 teeth on anterior half. 



Total length 19 mm. 



3. MOGGBIDGEA COEGENSIS n. Sp. 



Type. I 2 (No. 5678) found by Mr. I. L. Drege at Coega, Uiten- 

 hage Division, in May, 1899. 



* The nests of Gorgyrella schreineri Pure. (Ann. S. A. Mus., v. 3, p. 26, pi. 1, 

 fig. 3, 1903) closely resemble these in many respects, the upper part of the hole 

 being similarly inclined and similarly shaped in both, except that in Gorgyrella 

 the spreading rim is much more steeply funnel-shaped to fit the strongly bevelled 

 edge of the lid.
