in front. The maxillae are twice as long as the labium. The 

 labium is as wide as long. 



The cephalothorax is dark rufous. In alcohol the abdomen 

 is transversely banded with dark aad pale rufous, with a wide dark 

 band near the posterior end. When dried the anterior half is 

 rufors A\"ith two transverse curved bands of white hairs : behind 

 the second of these is a wide blackish band and between this and 

 the spinnerets the colour is rufous. The palpi are pale. The legs 

 are light rufous, the fii'st pair unmarked, the second, third, and 

 fourth with a black line runnino; along: the anterior face. 



This spider is immature, but seems to belong to the genus Key- 

 serlingella. 



Dtnamius METAjiLicus, sp. nov. (Plate LXI. figs. 2-2 c.) 



S . Length 6*8. Length of cephalothorax 3 ; width of cephalo- 

 thorax 2-4. 



Legs 3, 4, 2, 1, nearly equal in length ; the first three pairs stouter 

 than the fourth. 



The cephalothorax is high and convex. The cephalic part is 

 inclined forward and has the sides nearly vertical and parallel. 

 Tbe thoracic part has a nearly plane semicircular plate behind the 

 dorsal eyes, from which it rounds downward on the sides and behind ; 

 it is very much narrower on the upper surface than below, the sides 

 being concave. The quadrangle of the eyes is a little \\ider in 

 front than behind, is one-fourth wider than long, and occupies not 

 quite two-fifths of the cephalothorax. The eyes are all large. 

 The first row is plainly curved with the eyes a little separated, the 

 middle being less than twice as large as the lateral. The second 

 row is halfway betw een the first and third rows. The dorsal eyes 

 are a little smaller than the lateral and form a row which is not 

 quite so wide as the cephalothorax, although it is as wide as the 

 upper surface. The clypeus is two-thirds as high as the middle 

 eyes of the first row. The falces are slightly retreating, short and 

 not very stout. The sternum is wide and is truncated in front 

 and behind. The maxillsB are short and are widely separated. 

 The labium is fidly as wide as long. 



The whole appearance of this spider is big, black, and burly. 

 The cephalothorax is ornamented with a pair of snow-white spots 

 on the cephalic and another on the thoracic part, while the sides 

 are encircled by a wide white baud. On the black abdomen is a 

 pattern in yellowish white with a tiuge of red, consisting of an 

 encircling band, a central, longitudinal, dorsal band, which in the 

 posterior half is broken up into spots, and a curved transverse band 

 on each side of the dorsum behind tiie middle. The palpus has the 

 femur and tlie proximal end of the patella covered with white hairs. 

 The first two pairs of legs have the joints much enlarged and 

 rounded ; in the third pair they are also enlarged but are lengthened 

 out ; the first, second, and third pairs have fringes of white hairs, 

 and have all the joints, excepting the tarsi, iridescent, with bril- 

 liant violet reflections. Some of this iridescence is also seen on
