Mr. J. Blackwall on new Species of East-Indian Spiders. 41 
ones nearly form a square, the two anterior ones, which are 
seated on a slight protuberance, being larger and rather nearer 
to each other than the posterior ones; the eyes of each lateral 
pair are placed apart on a tubercle, and are distant from the in- 
termediate ones. The falces are short, subconical, very powerful, 
convex in front, vertical, glossy, and armed with teeth on the 
inner surface; the maxille are short, straight, and greatly en- 
larged and rounded at the extremity; the lip is semicircular, 
but pointed at the apex; and the sternum is heart-shaped, with 
prominences on the sides, opposite to the legs, and terminates 
in a point. These parts are of a dark brown colour faintly 
tinged with red, the extremities of the maxille and lip and a 
large spot at the anterior part of the sternum having a yellow- 
red hue. The legs are short, moderately robust, provided with 
hairs, and of a dark brown hue tinged with dull red, particu- 
larly at the base of the joints; the fourth pair is the longest, 
then the first, and the third pair is the shortest ; each tarsus is 
terminated by claws of the usual number and structure. The 
palpi, which are short, resemble the legs in colour, and have a 
curved pectinated claw at their extremity. The abdomen is 
more than twice as broad as it is long, and has a transversely 
narrow oval form, with somewhat sinuous margins, and six 
strong, conical, horizontal, rugged, hairy, dark brown spines, 
two of which are situated at its posterior margin and two at 
each extremity of the firm, glossy, transversely oval dorsal shield 
or carapace; the two anterior spines are the smallest, and the 
two intermediate ones the largest of the six; between the two 
anterior spines there are ten depressions, constituting conspi- 
cuous red-brown spots, the four intermediate ones, which are 
the smallest, and nearly equal in size, forming a straight, trans- 
verse row, somewhat in advance of the rest ; four similar spots 
in the middle are disposed almost in a square, the two posterior 
ones being the largest and rather the widest apart ; between the 
two intermediate spines there are nine red-brown depressed 
spots; five, smaller than the rest, form a straight transverse 
row somewhat in arrear of the others, the intermediate one being 
much the smallest; the colour of the carapace is brownish 
yellow, and there is a spot between the two posterior spines, and 
a smaller one at the base of each, of the same hue; the under 
part is very convex, corrugated, marked with numerous depres- 
sions, and of a dark brown colour spotted with reddish yellow ; 
the spinners are encircled by a prominent rim, and are of a 
dark brown colour; a bold conical prominence of the same hue 
occurs immediately before them, and there is a small, obtuse, 
glossy, yellow protuberance near the base of each branchial 
operculum.
