directed forwards. Those of the posterior pair are separated 

 from each other by slightly more than an eye's diameter, this 

 interval being less than that which divides each from the hind 

 lateral eyes on its side. 



The h'(/s are rather slender, not very long, thinly clothed 

 with fine hairs ; and their relative length appears to be 1, 4, 

 2,3. 



The falces are not very strong, moderately long, vertical, 

 and a little divergent at their extremities. 



The palpi are short, the radial and cubital joints about equal 

 in length ; but the former is much the strongest ; its fore part on 

 the upperside is rather produced ; and its extremity is indented, 

 leaving two small points or projections, of which that on the 

 inner side is longer, stronger, and more obtuse than the other. 

 The digital joint is rather large, of a somewhat roundish form, 

 rather flattened or truncate at its fore extremity. The palpal 

 organs are not very complex, consisting chiefly of two rather 

 strong reddish yellow-brown, curved, continuous processes. A 

 long slender, tapering, black, filiform spine runs from the inner 

 side beneath and round the margin, and across the fore extre- 

 mity of the digital joint, projecting rather prominently from the 

 outer extremity, its fine thread-like point in contact with some 

 whitish membrane. 



The maxiUce and labium are of normal form, and call for 

 no special notice. 



The sternum is large, considerably convex, and very glossy. 



The abdomen is oval, very convex above, and glossy ; it 

 had (so far as I could see) no hairy clothing, thougli perhaps 

 the hairs were originally very few and fine and had been 

 rubbed off. 



A single example of this little spider was also sent to me 

 some time ago by Dr. Ludwig Koch, by whom it was found 

 near Nuremberg. It is allied to Walckenaeraprcecox, Cambr., 

 and also to W. subitanca^ Cambr., and to Erigoiie pallens, 

 Cambr., but may easily be distinguished by the position of 

 the eyes, the form of the radial joints of the palpi, and the 

 structure of the palpal organs. 



Walchenaera orbiculata^ sp. n. (PI. XIII. fig. 2.) 



Adult male, length -^-^ of an incli. 



The cephalothorax, legs, palpi,' and falces of this spider are 

 of a yellowish hue, slightly tinged with brown ; the cephalo- 

 thorax is margined by a fine black line, and the tibia; and 

 metatarsi of the first pair of legs (with the tibia; of the second 

 pair, which arc less decjily tinged) of a deep yellow-brown hue ;
