 not very complex in structure, and of a brown-black colour. 



Sphasus italicus appears to be a common species in the vicinity 

 of Lucca, as the collection of Spiders made by Dr. Wright in that 

 locality contained many specimens of both sexes.

Length of the female ^in.; length of the cephalothorax -^, breadth gV; 

 breadth of the abdomen -^ ; length of a posterior leg ^ ; length of a 

 leg of the second pair ^. 



The cephalothorax is large, glossy, somewhat quadrilateral, has a 

 shallow indentation in the medial line, slopes abruptly at the base, 

 and projects a little beyond the falces, in front; it is of a brown 

 colour, the cephalic region and the narrow lateral margins, which are 

 much the darkest, being almost black; a yellowish-brown band 

 passes from the anterior part of the medial indentation to the base ; 

 and a band of a slightly darker hue, which tapers from its base to its 

 extremity, extends along each side to the frontal margin, where the 

 two unite. The minute intermediate eye of each lateral row is nearer 

 to the posterior than to the anterior eye of the same row. The falces 

 are small, conical, vertical, and of a pale brown colour tinged with 



- red. The lip is short, oval, and of a dark-brown hue at the base, that 

 of the apex being yellowish-brown. The maxillai are straight, and 

 enlarged and rounded at the extremity; and the sternum is oval. 

 These parts have a yellowish-brown hue, the margin^ of the sternum 

 being the darkest. The legs are robust, of a brownish-yellow colour, 

 with dark-brown annuli, and are provided with hairs and spines, two 

 parallel rows of the latter extending along the inferior surface of the 

 tibiae and metatarsi of the first and second pairs ; the fourth pair is 

 the longest, then the third, and the second pair is the shortest; each 

 tarsus is terminated by two slender, curved claws, and below them
