Mr. J. Blackwall on newly discovered species 0/ Araneidea. 19 



prominent at the apex. These parts are of a very dark brown 

 colour. The four intermediate eyes describe a trapezoid whose 

 anterior side is the shortest, and those of each lateral pair are 

 seated obliquely on a tubercle and are nearly contiguous ; the 

 anterior eyes of the trapezoid are the smallest of the eight. Legs 

 long, slender, provided with hairs and a few fine spines, and, 

 with the palpi, of a bright yellowish red hue. The first pair of 

 legs is the longest, the second pair surpasses the fourth, and the 

 third pair is the shortest ; each tarsus is terminated by three 

 claws ; the two superior ones are curved and slightly pectinated, 

 and the inferior one is inflected near its base. Abdomen ovi- 

 form, glossy, black, sparingly supplied with hairs, convex above, 

 projecting over the base of the cephalo-thorax ; the sexual organs 

 have a dark brown hue ; a prominent process is connected with 

 their superior and another with their inferior margin ; the former, 

 which is the larger, is nearly semicircular, concave within, and 

 has a longitudinal septum in the middle; the inferior one is 

 somewhat enlarged at its extremity and directed backwards. 



This species, which appears to be nearly allied to Linyphia 

 nigella, was received in July 1853 from Mr. R. H. Meade, who 

 captured it near Bradford ; and in November, in the same year, 

 Mr. Meade transmitted to me an adult female Linyphia anthra- 

 cina, which had been sent to him from Southgate, in Middlesex, 



Linyphia pulla. 



Length of the female ^th of an inch ; length of the cephalo- 

 thorax 2'p ; breadth -^-^ ; breadth of the abdomen ^V, ; length of 

 an anterior leg \^ ; length of a leg of the third pair 5%. 



Cephalo-thorax oval, convex, glossy, with an indentation in 

 the medial line : falces powerful, conical, armed with a few teeth 

 on the inner surface, slightly divergent at their extremities, and 

 inclined towards the sternum, which is heart-shaped : maxillae 

 straight, with the exterior angle, at the extremity, curvilinear : 

 lip semicircular and prominent at the apex. These parts are of a 

 brown-black colour, the sternum, lip, and lateral margins of the 

 cephalo-thorax being the darkest, and the falces having a tinge 

 of red. The four intermediate eyes describe a trapezoid whose 

 anterior side is the shortest, and those of each lateral pair are 

 seated obliquely on a tubercle and are almost contiguous ; the 

 posterior eyes of the trapezoid are the largest, and the anterior 

 ones much the smallest of the eight. Legs long, slender, pro- 

 vided with hairs and a few fine spines, and of a light yellow- 

 brown hue ; the first pair is the longest, then the second, and 

 the third pair is the shortest ; each tarsus is terminated by three 

 claws ; the two superior ones are curved and slightly pectinated,
