760 rev. o. p. Cambridge on [June 18, 



Cephalothorax dull yellow-brown ; legs and palpi pale dull 

 yellow, with a brownish tinge ; abdomen black. 



The upper part of the caput is elevated into a not very high 

 couical eminence, which slopes all round gradually into the sides ; the 

 summit is furnished pretty thickly with hairs. The eyes are placed 

 at the base of the cone, almost forming a ring round it ; they are in 

 four pairs ; those of the foremost pair equally divide the height of the 

 facial space, and are small and not quite contiguous to each other ; 

 those of each lateral pair are contiguous to each other and are the 

 largest of the eight ; each eye of the posterior pair is placed a little 

 above and behind the hinder eye of the lateral pair on its side, the space 

 between the posterior eyes being thus much greater than that between 

 each and the lateral eye nearest to it. Legs moderately long, rather 

 slender, and furnished with hairs only. The palpi are not very long ; 

 the radial joint is produced over the base of the digital into a broad, 

 rather oblong, oval form, slightly emarginate at its fore extremity, 

 the inner corner of this portion being produced into a sharp-pointed 

 corneous spine, which bends round sharply outwards, and its promi- 

 nent point extends beyoud the outer corner of the emargination. The 

 cubital joint has a single small tapering bristle at the edge of its fore 

 extremity on the upperside, directed downwards ; the digital joint 

 is not very large, and of oval form ; the palpal organs are neither very 

 prominent nor complex. 



An adult male of this very distinct little species was received from 

 Dr. L. Koch, by whom several examples have been found in the 

 neighbourhood of Nuremberg. 



Erigone (Walckenaera) scurrilis, sp. n. (Plate LXVI. 

 fig. 17.) 



Male adult, length T X T of an inch. 



The cephalothorax is large and bluff before ; and the caput is ele- 

 vated (principally on the occiput) into a considerable subcorneal 

 eminence, which leans rather backwards ; the profile line from the 

 summit of this eminence to the fore central pair of eyes is sloping, 

 and very slightly impressed below the middle ; from this point to 

 the margin of the clypeus it runs in a slightly convex form ; the 

 face and upper portion of the elevation is furnished with strong 

 bristly black hairs, those nearest the summit spreading over the sides 

 and behind, where several, stronger and longer than the rest, droop 

 and fall backwards like a queue. The eyes are all very minute, and 

 seated on black spots 5 those of the fore central pair are the smallest 

 of the eight, and are placed a little below the commencement of the 

 eminence on the caput ; those of each lateral pair are seated obliquely 

 and are in the same straight line as the fore centrals ; above each 

 lateral pair, and at about the same distance from them as they are 

 on either side from the fore central pair, is placed one of the hinder 

 pair of eyes ; these are widely removed from each other, on the sides 

 of the lower part of the subconical elevation of the caput, and, with 

 the fore centrals, form as nearly as possible (when looked at from the 

 front) an equilateral triangle.
