eyes of the trapezoid are much the largest, and the anterior ones, which 

 are placed on an eminence, the smallest of the eight. Mandibles power- 

 ful, conical, armed with two rows of teeth on the inner surface, and in- 

 clined towards the sternum, which is heart-shaped, glossy, and thinly 

 covered with long, erect hairs. Maxillee strong, straight, and somewhat 

 quadrate. Lip semicircular and prominent at the extremity. The man- 

 dibles and maxillae are brown, with a faint tinge of red, and the sternum 

 and lip brownish black, the latter being dark brown at the tip. Legs 

 and palpi long, and of a yellowish brown colour, with brownish black 

 bands. First pair of legs the longest, then the second, third pair the 

 shortest. Each tarsus in this, as in the other species of Linyphia, is ter- 

 minated by three claws ; the two superior ones curved and pectinated, 

 and the inferior one inflected near its insertion. The palpi have at their 

 extremity a long, slightly curved claw, minutely dentated more than half 

 its length from the base. Abdomen thinly covered with hairs, very con- 

 vex above, projecting over the base of the cephalo-thorax ; it is of a yel- 

 lowish brown colour, freckled with small, whitish spots, which are fewer 

 in number and more minute on the under side ; on the anterior part of 

 the upper side are large, brownish black blotches, and on the posterior 

 part numerous transverse, curved lines of the same hue, whose convexities 

 are directed forwards ; the sides are brownish black, with an irregular, 

 longitudinal band of yellowish brown, spotted with white, extending 

 along the middle. The spinners are brown, and at the base of the 

 inferior pair are three confluent, yellow spots, forming a rhomboid. A 

 small, cylindrical, semitransparent process is connected with the anterior 

 part of the sexual organs, within the external orifice. Plates of the spi- 

 racles pale yellow. 



The male bears a strong resemblance to the female, but is rather 

 smaller and darker coloured than she is ; the anterior part of the cephalo- 

 thorax also, on which the eyes are seated, is more elevated. The relative 

 length of the legs is the same in both sexes, but their absolute length is 

 greater in the male, an anterior one measui'ing ^f ths of an inch. Third 

 and fourth joints of the palpi short, the former having a long bristle pro- 

 jecting from its extremity, in front ; the latter, which is the larger, is of
