gular point from its inner margin towards the medial line. The 

 falces are slender, conical, vertical, and of a yellowish-red hue, 

 with a dark-brown spot at the extremity, towards the outer side. 

 The maxillae are short, straight, powerful, and enlarged and 

 rounded at the extremity ; and the lip is semicircular, but some- 

 what pointed at the apex. These organs have a dark-brown 

 hue, with pale yellowish -brown extremities. The sternum is 

 heart-shaped, with small eminences on the sides, opposite to the 

 legs; it is of a brown-black colour, with a broad, yellowish- 

 white band extending along the middle, which projects two 

 points from each side into the dark margins. The eyes are 

 seated on black spots on the anterior part of the cephalothorax ; 

 the four intermediate ones form a square, the two anterior ones 

 being placed on a tubercle, and the eyes of each lateral pair are 

 placed obliquely on a minute tubercle and are contiguous, the 

 anterior one being the smallest of the eight. The abdomen is 

 oviform, convex above, and projects over the base of the cephalo- 

 thorax ; the upper part is clothed with whitish silky hairs, and 

 is freckled with dull yellow at its anterior extremity, near which 

 there are four minute spots forming a curved transverse row 

 whose convexity is directed backwards, the two intermediate 

 ones being the smallest ; a minute spot, jfollowed by two streaks, 

 occurs on each side of the medial line, to which succeeds a 

 transverse curved row of very minute spots whose convexity is 

 directed upwards; these spots and streaks have a brownish- 

 black hue; the lower region of the sides and the under part are 

 of a brown-black colour, a somewhat dentated yellowish-white 

 band extending along each side of the latter; the branchial 

 opercula are of a reddish-brown colour, and that of the spinners 

 is yellowish'brown, the extremity of the superior pair having a 

 brown-black hue on the upper surface. The legs are long, 

 slender, and supplied with hairs and fine spines ; the femora of 

 the anterior pair are of a very dark-brown colour, that of the 

 femora of the three other pairs being yellowish -brown ; all are 

 tinged with red at the extremity, and the other joints have a 

 red-brown hue ; the femora of the third and fourth pairs have a 

 longitudinal black line on their anterior surface, and the coxae 

 of all the legs have a black spot on each side ; the first pair is 

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

 each tarsus is terminated by the customary number of claws 

 of the usual structure. The palpi are short, and of a pale yel- 

 low colour, with the exception of the digital joint, which has a 

 dark-brown hue tinged with red ; the cubital and radial joints 

 are short ; the former projects a long bristle from its extremity 

 in front, and the latter is produced and fringed with hairs on 

 the inner side ; the digital joint is oval, with a process at its
