434 Mr. J. Blackwall on newly discovered species of Araneidea. 



those organs and the falces is broad and nearly vertical ; it is of 

 a yellowish- white colour, the lateral margins, a streak directed 

 from each intermediate eye to the frontal margin, two irregular 

 confluent, spots on each side, and a broad band extending along 

 the middle, having a dark brown hue. The eyes are placed on 

 black spots ; the two intermediate ones are much the smallest 

 of the eight, and are situated transversely between, or rather 

 slightly in advance of, the three large ones on each side, which 

 are closely grouped in the form of a triangle. The falces are 

 small, vertical, subconical, united at the base, armed with a short, 

 slightly curved fang, and have a single strong tooth at their 

 extremity, on the inner side : the maxillse are long, and taper to 

 the extremity ; they are greatly enlarged at the base, where the 

 palpi are inserted, and inclined towards the lip : the palpi are 

 short, and provided with long hairs. These organs have a pale 

 yellow-brown hue, the maxillae being the palest. The lip is 

 short, broad, somewhat dilated in the middle, and rounded at 

 the apex ; and the sternum is heart-shaped. These parts are of 

 a dark brown hue, the apex of the lip having a yellowish -brown 

 tint. The abdomen is of an oblong oviform figure, sparingly 

 clothed with short hairs, and of a pale yellowish-white colour ; 

 at the anterior extremity of the upper part there are two short, 

 obscure, brownish streaks directed backwards ; these are followed 

 by a faint, fusiform, longitudinal band of the same hue, which 

 is bifid at its posterior extremity ; it is succeeded by a double 

 series of oval, brownish-black spots disposed in pairs and in- 

 clined towards each other ; immediately above the spinners there 

 is a pale yellowish- white space bounded by an irregular, brownish- 

 black line, and on the upper part of the sides curved lines of the 

 latter hue occur ; the anterior extremity of the under part has a 

 dark brown hue, and three bands of the same colour extend 

 along the middle ; the intermediate one is narrower and shorter 

 than the two exterior ones, which are greatly contracted near 

 the spinners, where a pale yellowish-white space occurs, bounded 

 by the extremities of the three medial bands ; the sexual organs 

 are prominent, and of a reddish-brown colour. 



I am indebted to Mr. Eyton Williams of Denbigh for this 

 remarkable Pholcus, which he captured in Pernambuco. It 

 differs from the known species of the genus to which it belongs 

 in having the posterior legs decidedly longer than those of the 

 second pair, — a character constituting an additional bond of 

 alliance to those previously known to connect the spiders of this 

 small group with those of the genus Artema,
