1874.] REV. O. P. CAMBRIDGE ON NEW DRASSIDES. 381 



The eyes are placed in the usual two transverse lines ; the hinder 

 row is slightly the longest and straight, the fore one a little curved ; 

 the eyes of the hind central pair appear to be the smallest of the 

 eight, and the fore laterals the largest ; the hind laterals are very 

 small and obliquely placed ; the four eyes of the hinder row are 

 equidistant from each other ; each hind lateral is separated from the 

 fore lateral on its side by rather less than the diameter of the former ; 

 the fore laterals are large, slightly obliquely placed, of a somewhat 

 oval form ; the fore centrals are also large, round, and contiguous 

 to each other, and each is contiguous to the fore lateral on its side. 



The leys are rather long and strong, particularly the femoral joints ; 

 their relative length is 1, 4, 2, 3 ; they are of a dark brown colour 

 tinged with olive ; the two basal joints, however, as well as the me- 

 tatarsi and tarsi, are yellow-brown ; the tarsi of the fourth pair are 

 palest and tinged with red ; they are furnished with hairs ; and there 

 are some not very strong spines, principally on the tibiae and meta- 

 tarsi of the third and fourth pairs. 



The palpi are short, tolerably strong, and of a yellow-brown colour ; 

 the cubital and radial joints are very short, but of equal length ; the 

 latter has its outer extremity produced into a not very long, tapering, 

 deep- shining brown apophysis, whose pointed extremity curves up- 

 wards ; the digital joint is large and of a broadish oval form, its 

 length exceeding that of the radial and cubital joints together. The 

 palpal organs are well developed : they consist of several largish 

 prominent corneous lobes and processes ; and a long tapering black 

 spine issues from their fore extremity and forms a bold coil or bend 

 near the middle of their outer side, from which part also there issues 

 another much shorter, curved, prominent, pointed, black spine. 



The falces are neither very long nor strong ; they project forwards, 

 and, with the maxillee, labium, and sternum (which are all of normal 

 character), are of a dark yellowish-brown colour. 



The abdomen is oblong-oval in form, and rather flattened ; it is 

 moderately clothed with hairs and of a nearly black colour ; a large 

 patch of a subtriangular form occupies the fore part ; this patch is 

 of a rather shining coriaceous nature and deep brown colour; be- 

 neath the fore part are some long, strong,. upturned, bristly hairs. 



A single example was found by myself under a stone near Alex- 

 andria in April 1864.

Adult female, length 2f lines. 



In its general yellow colouring this species resembles P. pallida 

 (postea, p. 383) ; but it may be easily distinguished by the closer 

 grouping of the eyes, the two rows of which, however, are further 

 apart, the hinder row being much more curved ; the spinners of the 

 inferior pair are also much shorter ; the legs too are shorter, and the 

 genital aperture differs greatly in form. 



There is nothing noticeable as different from the normal type in 

 the form of the cephalothorax, except that the lateral constriction 

 of the caput is rather more marked; it is (as well as the whole of
