sides, and the profile of the clypeus (which considerably ex- 

 ceeds in height half that of the facial space) continues the 

 curve of the profile of the occiput ; the profile line behind the 

 occiput exhibits a very slight depression ; on the caput and 

 clypeus are some prominent hah'S. 



The eyes are small, and, excepting the fore-centrals, which 

 are very small, are of equal size ; those of the hind-central 

 pair are considerably nearer together than each is to the hind- 

 lateral eye on its side, the interval being no more than an 

 eye's diameter, which is also the same interval as that which 

 separates them from the fore-centrals ; those of each lateral 

 pair are placed obliquely on a tubercle ; the fore-centrals are 

 dark, indistinct, and contiguous to each other. 



The leys are of tolerable length and rather slender ; their 

 armature had been almost entirely denuded, but it appears to 

 have consisted of hairs only. 



The palpi are short ; the radial joint is stronger, but scarcely 

 longer, than the cubital, both being very short ; the former 

 spreads out a little in front, but has no projection or apo- 

 physis ; it is furnished with some bristly hairs, the longest 

 and strongest of which are on the outer side ; the digital joint 

 is of moderate size, and has a strong lobe or prominence to- 

 wards its hinder extremity on the outer side ; the palpal 

 organs are moderately complex ; at their base on the outer 

 side is a prominent, almost circularly curved, corneous process, 

 and at their extremity are two or three small, blunt, projecting, 

 corneous points. 



The falces are long, strong, and greatly inclined back- 

 wards to the labium ; they are also a little divergent at their 

 extremities. 



The abdomen is of tolerable size ; its shape is a regular 

 oval, its surface glossy and very sparingly clothed with hairs ; 

 and it projects a little over the base of the thorax. 

 '" This spider is allied to Neriene Huthwaitii, Cambr., which 

 it resembles very much in general colouring and appearance ; 

 but it may easily be distinguished by the much shorter radial 

 joint and much larger digital joint of the palpus ; the struc- 

 ture also of the palpal organs is entirely different. 



A single example was sent to me for examination by Count 

 Keyserling, by whom it was found at Dux.

Adult female, length \ of an inch. 



The whole of the fore part of this spider, including the legs 

 and palpi (which are a little the palest), is of a clear yellow 

 colour ; and the abdomen is pale straw-coloured. The cephalo-
