The eyes are large, and are placed, as usual, in two transverse curved rows, of which the foremost one is slightly the longest, and the hinder one the most curved, the area they describe being no more than one third longer in its transverse than in its longitudinal diameter : the hind centrals are oval, oblique, of a pearl-grey colour and margined with black; they are very near together and not quite contiguous; and the interval that separates them is about equal to that which divides each from the hind lateral nearest to it, being no more than one fourth of a hind central eye's diameter: each hind lateral is separated by half its diameter from the fore lateral next to it, and is contiguous to the fore central eye on its side. The fore centrals are unusually large for these eyes, being as large or larger than the fore laterals ; they are round, dark-coloured, separated from each other by rather less than half a diameter, and (like the same eyes in many others of the genus) placed on somewhat of a slight eminence: the four lateral eyes are margined with black, and of a pearl-grey colour, but not quite so dark as the hind laterals. The falces are small and almost vertical. The legs are shortish; relative length 4, 1, 2, 3, moderately strong, furnished sparingly with hairs, and with a few short weak spines on the tibiae and metatarsi of the two hinder pairs; there are also one or two longer and stronger ones on the fore sides of the femora of the same pairs. The maxilla are normal in size and form ; but the palpi issue from the middle point of their length. The labium also is normal. The abdomen is oblong-oval, truncated before ; it is sparingly clothed with hairs, and is of a pale dull luteous yellow colour ; it projects but very slightly over the base of the cephalothorax, and at that part has some strong upturned bristles: four impressed dusky spots form a largish quadrangular figure on the fore half of the upper side; this figure is longer than broad, and its fore side is slightly shorter than the hinder one : a narrow, somewhat tapering, indistinct dusky marking is defined by two nearly parallel dusky lines along the middle of the fore half, running between the two foremost of the above-mentioned spots. The spinners of the inferior pair are not as long as in many other species, but much longer than those of the superior pair. The form of the genital aperture is simple, but peculiar (vide Plate LI. fig. 9 ) . A single adult female was found by myself under a stone near Alexandria, in April 1864. PROSTHESIMA CINGARA, sp. n. (Plate LI. fig. 10.) Adult female, length not quite 3 lines. In general form and structure this species presents nothing peculiar, and in its dark and sombre colouring it m u c h resembles P. pedestris (Koch) and P. tristicula (Cambr.) ; the form of the |
