that distance from the laterals. The front and rear laterals are on a common pro- 

 tuberance, half their diameter apart ; they are equal in size, and almost the same as 

 the rear median. 



The front row is straight, and shorter than the rear row. The median pair are 

 only half the diameter of the rear median, and twice their diameter apart, and nearly 

 twice that distance again from the rear median. They are rather farther from the 

 side eyes than from one another. The breadth of the clypeus is the same as their 

 distance from the side eyes. 



The mandibles are twice as long as broad, straight, and only slightly kneed at 

 the base. There are 3 quite small teeth on the inner side of the falx-sheath, and 3 

 larger on the outer. 



The maxillae are upright, straight on the inner side, and only slightly curved 

 on the outer. 



The lip is as broad as long, and about half the length of the maxillae, straight 

 but slightly hollow in front. 



The sternum is shield-shaped, broad and truncate in front, pointed at the rear, 

 where the 4th pair of coxae are quite contiguous. The legs are moderately long and 

 strong, on the metatarsus of the 4th pair is a well-formed rather long calamistrum ; 

 there are single spines on all the metatarsi, 1 median underneath on tibia iii and iv, 

 and 1 each on the femora above, the underside being smooth. The superior tarsal 

 claws are well curved, and have about 7 pectinations. The inferior seem to be smooth. 



The abdomen is ovate, rounded both anteriorly and posteriorly, the latter end 

 pointed. The cribellum is double, with well-defined spines on it. The spinnerets 

 are normal. 



This species so nearly resembles the Amaurobius from the same locality (described 

 above) in its eyes, coloration, and proportions generally, although only two-thirds the 

 size of the non-adult male, that it seemed as if it must be a smaller but adult of the 

 same. However, the mandibles are not so much kneed at the base ; the lip is very 

 clearly shorter ; and the maxillae are narrower, and not nearly so much rounded 

 on the outer side. 



The cribellum is double, and the calamistrum well marked ; the front median 

 eyes smaller in proportion ; also, the rear coxae are quite contiguous, instead of half 

 their width apart. 



In all other respects there is nothing to distinguish them. The difference in the 

 cribellum is often sexual, but the lip is quite clear. 



The measurements (in millimetres) are as follows : Cephalothorax, 4J mm. 

 long, 3 mm. broad (2 mm. in front) ; abdomen, 5 mm. long, 3 mm. broad ; mandibles, 

 2 mm. long.
