form a transverse straight line ; the interval between those of 

 the hind-central pair being greater than that between each and 

 tho hind-lateral eye on its side ; the fore-central pair are placed 

 on a prominence which brings them rather considerably in 

 advance of tho rest. 



The legs are long, slender, and tapering, furnished with hairs, 

 and distinct, prominent, but not very strong, spines ; they are 

 similar in colour to the cephalo-thorax, excepting the tibiso and 

 metatarsi of the first, second and fourth pairs, and part of the 

 metatarsi of the third pair, all which are deep blackish-brown. 

 The lengths of the 2nd and 4th pair differ but little if anything ; 

 the 1st pair are the longest, and the 3rd shortest. The palpi are, 

 like the legs, furnished with hairs and spines ; they are of a 

 yellow-brown colour, the radial and digital joints being black- 

 brown. 



The abdomen is oviform, and projects a little over tho hinder 

 part of the thorax ; it is of a dull yellowish-brown hue marked 

 (especially above) with numerous irregularly-shaped, yellowish- 

 white, somewhat shining, cretaceous spots, whose disposition 

 leaves an indistinctly defined, longitudinal, central, yellowish - 

 brown stripe on tho fore-half of tho upper side, and some oblique 

 lateral ones. 



The genital aperture is small, not very prominent, but of 

 characteristic form, and dark red-brown colour. 



A single oxamplo of this spider was kindly sent to me by Mr. 

 F. "Workman, by whom it was found near Belfast in the autumn 

 of 1878. It is allied to Linyphia luteola, Blackw. (p. 194), but 

 the dark brown portion of tho legs and palpi distinguish it at 

 once from that, and from all other nearly allied species known 

 to me.
