BY

THE REV O. PICKARD-CAMBRIDGE.


Genus Cteniza, Latr.

Cteniza Moggridgii, sp. n., Plate XX., fig. A, p. 254.

Cteniza fodiens (Camb.)? [female] in Harvesting Ants and Trap-door Spiders, J. T. Moggridge, 1873, p. 89, Plate VII., excluding synonyms there quoted.

Adult male length 5-1/2 lines, length of cephalothorax 3 lines, breadth 2-1/2.

The cephalothorax is of a short, broad-oval form, its length being only half a line greater than its breadth; it is flattened-convex above, and depressed near the margins, the caput (when looked at in profile) scarcely rising above the level of the thorax. At the junction of the caput and thoracic segments is a deep, circularly-curved indentation, or fovea, the curve of which is directed backwards; the extremities of this indentation are continued obliquely forwards on either side, forming the normal ones which indicate the junction of the caput and thorax. Rather more than one-third of the distance between the above curved indentation and the fore margin of the caput is a very perceptible and deep but narrow, slightly curved, transverse indentation which divides the caput into
