dull greenish yellow-brown colour ; the margins and some 

 vein-like converging lines blackish, and the fore part slightly 

 suffused with a sooty hue. The hinder slope has a very large, 

 deepish, extended indentation, giving it a hollow appearance 

 in profile, with a prominence at the thoracic junction, and a 

 correspondingly deep depression directly behind the occiput, 

 which is a very little gibbous ; the ocular area slopes for- 

 wards ; and the clypeus (seen in profile) projects in a slightly 

 upturned form : the whole profile line is thus characteris- 

 tically, but unusually, irregular. 



Behind each lateral pair of eyes is a slight longitudinal 

 indentation running backwards. The ocular area is of a 

 broadish transverse-oval shape ; and the eyes are rather closely 

 grouped together : those of the hind-central pair, which are 

 the largest, are further from each other than each is from the 

 lateral on its side, the interval being about equal to an eye's 

 diameter ; the interval between the fore-centrals is very 

 small, and each is contiguous to the fore lateral next to it ; 

 the lateral pairs are placed very slightly obliquely. 



The legs are slender, rather short, of a pale orange-yellow 

 colour, furnished with hairs and, chiefly on the tibial joints, 

 with a few erect slender bristles. 



The falces are small, straight, slightly inclined backwards, 

 and (with the maxillaj, labium, and sternum) similar in colour 

 to the cephalothorax. 



The abdomen is large, tolerably convex above, of a some- 

 what oblong-oval form, and projects, though not greatly, 

 over the base of the thorax ; it is of a dull black hue tinged 

 with olive, glossy, and very sparingly clothed with hairs. A 

 very broad strong prominent process is connected with the 

 genital aperture, the extremity being of a somewhat recurved 

 form. 



A single example of this spider was received about the 

 middle of June 1879 from my cousin, Colonel Pickard, R.A., 

 by whom it was found at Balmoral Castle, Scotland. The 

 very peculiar and irregular profile line of the cephalothorax, 

 the projecting clypeus, and prominent genital process will 

 serve to distinguish this species from all its congeners known 

 to me. 



Neriene improba } sp. n. (PL XII. fig. 6.) 



Length of the adult male, y 1 ^ of an inch. 



Cephalothorax dark black-brown tinged with an olive- 

 greenish hue. Ocular area somewhat produced forwards, but 

 with no eminence or elevation on the caput ; profile level, the 

 dip between the caput and thorax very slight.
