SYNAMA. 81 
Synema palliata, sp. n. 
Adult female, length 2 lines. 
The cephalothorax is of ordinary form, of a greenish-yellow hue tinged with reddish in the ocular region, and 
the sides of the thorax broadly dull red-brown, clothed thinly with short hairs and furnished with a few 
strongish black bristles directed forwards. 
The eyes of the central trapezoid form nearly a square: the hinder side is longest, and the anterior the shortest ; 
this last and the sides are as nearly as possible equal. This central figure is thus shorter than normal. 
The eyes of the hind central pair are distinctly further from each other than from the hind laterals, and 
those of the fore central pair are distinctly (though only a little) further apart than from the fore laterals. 
The height of the clypeus is less than, though more than half, that of the facial space. 
The falces are strong, moderately long, subconical, vertical, furnished with several strong bristles near the base, 
and of a reddish-yellow-brown colour. 
The legs are rather short, 1, 2, 4, 3, tolerably strong ; spines and hairs normal. The femora, genua, and tibie 
of the first and second pairs are dark reddish-yellow-brown, the tibise having a broad yellowish band near 
the posterior extremity, extending to nearly half the length of the joint. The tarsi and metatarsi are 
yellow. The legs of the third and fourth pairs are of a uniform pale yellow colour. 
The palpi are similar in colour to the hinder pairs of legs. 
The maaille are yellow-brown, the labium of a more sooty hue, and the sternum pale yellow. 
The abdomen is short, subpentagonal, very convex above, rounded before, obtusely pointed behind. The upper- 
side, excepting a small portion above the spinners, is of a uniform cream-yellow colour, clothed with short 
paler hairs and a very few fine dark bristles. The portion above the spinners and the sides are somewhat 
rugulose, of a dark chocolate-brown hue, with lines of minute yellowish points following the courses of 
the different ruge. The underside is of a deeper and more uniform chocolate-brown. The spinners are 
short and of a dull brown colour. The genital aperture is small and inconspicuous, but characteristic.

Synema maculosa, sp. n. 
Adult male, length 14 lines; length of a leg of the first pair over 43 lines. 
The cephalothoraw is of a dull orange-yellow-brown colour, margined narrowly with black, above which but 
connected with it in the thoracic region is a broader black-brown border. 
The eyes are seated upon greyish subconical tubercles, those of the lateral pairs, especially the anterior ones, 
much the strongest. The eyes of the anterior row are equidistant from each other, while the interval 
between the hind central pair is slightly less than that between each and the adjacent lateral eye of the 
same row. ‘The four central eyes form nearly a square, the posterior side of the trapezoid being longest, 
the sides are next in length, and the fore side the shortest. The height of the clypeus is less than halt 
that of the facial space by about the diameter of one of the fore central eyes. 
The legs of the first pair are long and rather slender (those of the second pair are wanting in the example 
described). The femora, genua, and tibice of the first pair are dark reddish-brown, the metatarsi and tarsi 
of a paler hue (only two or three spines remain, the rest having been broken off—they would appear 
from the broken bases and those remaining to have been tolerably numerous, long, and moderately strong). 
The two hinder pairs of legs are, as usual, unicolorous, and of a pale yellow hue. 
The palpi are short, and similar in colour to the hinder legs. The radial joint is slightly shorter than the 
cubital, and its fore extremity on ‘the outer side terminates with a small, blackish, tapering, pointed 
apophysis. The digital joint is of moderate size, oval form, and yellow-brown colour. The palpal organs 
are simple and partly encircled with a black spine. 
The falces are of tolerable length and strength, subconical, and vertical ; their colour is similar to that of the 
cephalothorax. 
The mawille, labium, and sternum are normal in form and similar in colour to the falces, ' 
The abdomen is of a rather elongate-oval form, rounded at each end, somewhat flattened above, and the upper- 
side seems to form somewhat of a shield or carapace, enveloping the under part (but this may be only the
