ON SOME NEW AND RARE BRITISH ARACHNIDA. 87 



size ; fore-laterals, if anything, slightly largest ; each lateral pair 

 slightly obliquely seated on a common low tubercular eminence ; 

 height of clypeus less than half that of the facial space. 



Legs moderate in length and strength ; not very unequal in 

 length, i, 4, 2, 3, thinly clad with hairs only, excepting two or 

 three slender erect bristles on the femoral and tibial joints ; tarsi 

 and metatarsi of equal length. 



Fakes strong, straight, vertical, moderate in length, conical ; 

 teeth on inner extremity very minute. 



MaxillcB moderate in length, strong, a little bent, and leaning 

 over the labium. 



Labium short, its height half the length of its width, and its 

 upper margin a little flat-rounded. 



Sternum larger than broad, heart-shaped ; its anterior margin 

 pretty squarely truncate ; its posterior extremity a little drawn 

 out between the coxae of the fourth pair of legs and truncate, its 

 breadth there being equal to the breadth of the coxae. 



Abdomen oval, projecting considerably over the base of the 

 cephalothorax, thinly furnished with hairs ; the genital aperture 

 and process placed as nearly as possible at the middle between 

 their fore and hinder extremities ; spinners very short, the lower 

 pair strongest, but not much shorter than the upper pair, all 

 placed in a circular slight pit or cavity. 



Maro minutus, sp. n. Figs. 12-18. 



Adult female, length rather less than a millimetre, or about 

 i -25th of an inch. General colour pale dull yellowish. 



The eyes are all on black spots. The hinder row has the 

 convexity of its very slight curve directed backwards, and the 

 interval between the central pair is greater than that between 

 each and the hind-lateral eye next to it; the fore-centrals 

 are almost contiguous to each other, as well as to the fore- 

 laterals. The fore-centrals with the laterals thus form an almost 

 unbroken semi-circle.
