present genus to which it can be referred. Nothing is known of its 
habits ; the wide separation of the three groups of eyes, with the 
very peculiar form of the cephalothorax and the structure of the 
maxille, make it a remarkable species, and one which, when looked 
at from in front, might easily be mistaken for a four-eyed Spider. 
Nov. gen. Gira (nom. propr.). 
Characters of the Genus.—Cephalothorax rather depressed above, 
and rounded on the outer margin ; caput broad, flattened, and pro- 
duced in front into three prominent productions, all in the same 
plane; the central prominence bears the four central eyes at its ex- 
tremity in the form of a quadrangle, and each of the lateral promi- 
nences a lateral pair of eyes. 
Abdomen oval, pointed behind, not very convex above, armed on 
the upperside with tuberculiform spines, mostly surmounted with 
long and strongish bristles. 
Legs rather long, slender, armed tolerably thickly with hairs and 
long spine-like bristles ; tarsal claws three in number, toothed, and 
with some supernumerary opposed pectinated ones beneath ; relative 
length of legs 4, 1, 2, 3. 
Mazille strong, moderately long, inclined towards the labium, 
and obliquely truncate, rather on the outer sides, at their extremi- 
ties ; inner extremities pointed. 
Labium short, broad, and apex curved. 
(Era spinosa, n. sp. (Plate XLIV. fig. 7.) 
Male adult, length 13 line. 
The cephalothoraz has the thoracic region of a yellow colour ; the 
normal grooves and indentations are fairly marked ; the caput is of a 
deep brown, softening into a pale yellow-brown on the lower mar- 
gins, and furnished with long bristly hairs; the two lateral projec- 
tions at its fore extremity are rather pointed, of considerable length, 
divergent from and rather longer than the central prominence, which 
is, however, the strongest of the three, obtuse, and slightly impressed 
at its extremity. 
Eyes eight, not very unequal in size ; two contiguous to each other 
are placed at the extremity, on the outer side of and beneath each 
lateral prominence of the caput; a pair almost (but not quite) con- 
tiguous at the base on the upperside of the central prominence, and 
another pair at its extremity, much wider apart than those of the 
pair at its base, and, in fact, occupying its fore corners; these four 
form an oblong rectangular figure whose fore side is much the 
widest. Except those at the base of the central prominence, which 
are pearly white, the eyes are of a somewhat amber-colour of different 
shades. 
The colour of the legs is pale yellow. 
Palpi short, of a yellowish colour; the cubital, radial, and digital 
joints are dark brown; the cubital is short, pointedly prominent 
above, and has a long and somewhat sinuous dark spiny bristle
