form, and of a sooty, brown -black hue, thinly olothod with short, 

 pale hairs. The palpi are short, the digital joint is large, of a 

 long-pointod, oval shape, tumid at the base and pointed at its 

 extremity, like the undeveloped palpus of male spidors. The 

 genital aperture has a strong prominence connected with it ; and 

 had it not been for the plain ovidonce, as to sex, furnishod by 

 this latter portion of struoturo I should, without hesitation, have 

 decided the examples examinod to have boon those of 

 immature males. The eyes of the hind-oeutral pair are rather 

 further from each other than each is from the hind-lateral oyo 

 on its side ; those of each lateral pair are plaoed very slightly 

 obliquely, and are contiguous to each other. 



This romarkable spider is voi'y rare, among hoathor, at Blox- 

 worth ; and it may easily bo distinguished from all others yet 

 known to me, by the tumid digital joint of the palpus above 

 detailod. Mr. Dale has also mot with it among moss at Glan- 

 villos Wootton. 



NERIENE MOLLIS. 



Neriene mollis, Cambr., Trans, Linn. Soc, xxvii., p. 439. 



The length of the adult male is l-16th of an inch. 



This is a very minute and obscure species ; and, as it had only 

 recently moulted, it had not quite attained its permanent colours. 

 These appeared to bo (like those of many others of the genus) 

 yollow-brown on the cophalo-thorax ; legs and palpi yellow, and 

 abdomen brownish-black. Tho caput is level with the thorax, with 

 a shallow, notch-like depression between them, when seen in 

 profile ; the height of the clypeus is equal to half that of the 

 facial space. The eyes are closely grouped, of moderate sizo, and 

 do not differ much, in this respect, from each other ; those of the 

 fore-central pair aro not quite contiguous, but aro equally separ- 

 ated from each other, and from tho fore laterals. The intervals 

 also between those of tho hindor row are very nearly equal. The 

 palpi are very short, the radial is rather stronger than the cubital 

 joint, but is destitute of any terminal projection, or apophysis;
