AEANEIDEA. 
75 
interval being equal to the diameter of one of the fore-central eyes ; the interval between 
the eyes of each lateral pair is considerably less than that between the fore- and hind-central 
pairs, and as nearly as possible equal to that between the eyes of the hind-central pair. 
The leys are long and moderately strong, but do not differ greatly in length ; their 
relative length is 2, 4, 1, 3. They are of a greyish-sandy colour tinged with brown, minutely 
speckled with darker brown, and furnished with hairs, bristles, and spines ; the tarsi and a 
small portion of the metatarsi have a thin scopula on their under sides. 
The palpi are moderately long, similar to the legs in colour, except the radial and digital 
joints, which are strongly tinged with brown. The radial and cubital joints are short (the 
former being the shorter), and are armed with a few strong spine-like, tapering bristles. 
The digital joint is large, of an elongate oval form, rather pointed before and equal in 
length to the humeral joint, exceeding that of the radial and digital joints together. The 
palpal organs are simple, rather the most prominent at their base, with a long, contorted, 
dark-brown, narrow stripe (probably indicative of an internal duct) on their surface and a 
strongish, curved, prominent tooth-like spine at their anterior extremity ; the radial joint 
has a very small angular prominence at its extremity on the outer side, and a short, broadish, 
truncated apophysis underneath. 
Th efalces are rather long and slender, straight, and a little directed backwards ; their 
colour is like that of the cephalothorax. 
The maxilla} and labium are of normal form and similar to the falces in colour, the 
extremities of the maxillae, however, being of a pale-whitish hue. 
The sternum is heart-shaped, granulose, and of a brownish-yellow colour. 
The abdomen is oval, of a stone- white colour, speckled thickly with small punctures and 
minute black specks. The normal longitudinal marking on the fore half of the upper side is 
of a dark-grey hue, and has a prominent, obtuse point at the middle of each side, and its 
posterior extremity is pointed ; its outer margins and extreme hinder point are also indicated 
by a few black, and mostly linear, spots. The sides of the upper part are clouded with dark- 
grey, leaving a pale, median tapering band on the hinder half, and several oblique, white in- 
distinct stripes on the outer margins, where there is also a line of three or four black spots 
on each side ; these lines converge in the direction of the spinners. The sides are rugulose 
and the spinners short, compact, and tinged with a sandy colour. 
The female is rather larger than the male, but in colours and markings resembles it. 
The oblique white stripes on the lateral margins of the upper part are better defined, and 
consist of more or less confluent spots and elongate blotches. The form of the genital 
aperture is characteristic.

Sab . — One or two immature examples of this spider found at Murree (J une 11th to July 
14th, 1873) exactly resemble the types found in Palestine.
