which comprises the palpal organs ; these organs are moderately 

 developed, rather complex in structure, and of a red-brown 

 colour at the base, the hue of the anterior part, whose black 

 inner margin is curved, being dull yellow ; from a small dark 

 red-brown piece, situated near the middle of the outer side, pro- 

 ject two pointed processes, one of which is prominent and the 

 other is directed outwards towards the margin of the digital 

 joint. 



Since the female of this fine species of Lycosa was described 

 in the ' Annals and Mag. of Nat. Hist.,' I have received from 

 the Barao do Castello de Paiva specimens of both sexes, which 

 had been captured in the islands of Madeira, Porto Santo, and 

 Deserta Grande.

Length of the male (not including the spinners) -rfV of an 

 inch; length of the cephalothorax -fV^ breadth V^; breadth of 

 the abdomen -yV; length of an anterior leg ■\-; length of a leg 

 of the third pair -fV- 



The minute intermediate eye of each lateral row is rather 

 nearer to the anterior than to the posterior eye of the same row. 

 The cephalothorax is large, glossy, somewhat quadrilateral, 

 sloping abruptly at the base and projecting a little beyond the 

 falces in front ; it has a curved indentation in the middle, whose 

 convexity is directed forwards, and is of a reddish-brown colour ; 

 the lateral eyes are seated on brown spots, and there arc some 

 white hairs on its sides. The falces are short, subconical, verti- 

 cal, and have a brownish-red hue. The maxillae are straight, 

 and enlarged and rounded at the extremity, and the lip and 

 sternum are oval. These parts are of a yellowish-brown colour. 

 The legs are robust, especially those of the anterior pair, and 

 are provided with hairs and sessile spines, two parallel rows of 

 the latter occurring on the inferior surface of the tibia3 and 

 metatarsi of the first and second pairs ; they are of a brownish- 

 yellow colour, the inferior surface of the femora of the anterior 

 pair having a brown hue ; the first pair is the longest, then the 

 fourth, and the second and third pairs are nearly of equal length; 

 each tarsus is terminated by two curved claws, below which 

 there is a small scopula. The palpi resemble the legs in colour; 

 the cubital and radial joints are short, the latter being the 

 shorter; the digital is long, of nearly equal breadth, slightly 

 convex and hairy above, compact at the extremity, with a con- 

 cavity at the base, on the underside, comprising the palpal
