50 Mr. R. I. Pocock on a new Trap-door Spider. 
Mazille simply coxiform, fringed with reddish hairs along 
the anterior border, and having the anterior distal angle 
furnished with a few black spiniform teeth. 
Pali completely pediform, clothed with long hairs, the 
patella and tibia with the lower surface furnished laterally 
beneath with a few setiform spines, the tarsal segment scopu- 
late, the hairs being thick at the sides, but scanty on the 
middle of the lower surface, terminated by a single, curved; 
inferiorly dentate tooth. 
Legs.—The first, second, and third pairs subequal in length, 
the third being slightly the shortest, the fourth longer than 
the rest almost by its two terminal segments; clothed witi 
hairs but not armed with spines, there being at most a few 
spiniform sete scattered here and there. The first and second 
pair with the two distal segments furnished with ) thick 
undivided scopule; the third pair with the seopule very 
much reduced in size, but with two terminal tufts of hair at 
the base of the claws ; the fourth with similar terminal tufts’ 
and with the scopula almost absent. ‘Two simple strongly 
curved claws terminating each leg. 
» Labium united to the sternum, quadrate, wider than long, 
its anterior border straight and armed with a row of black’ 
spiniform teeth. 
Sternum longer than wide, ovate. 
Abdomen ovate; the superior spinners the longest, a very 
little shorter than the patellaof the third pair of legs, the 
segments markedly decreasing in size from the base to the 
apex, the apical segment very short and conical ; the inferior 
spinners composed of a single segment, which is about half 
the length of the basal segment of the superior spinners. 
Measurements in millimetres.—Total length 15°5; length 
of cephalothorax 6°5, width 5°5; distance of fovea from ante- 
rior border 4; length of abdomen 9; length of palp 11, of 
first leg 14°5, of second 14:5, of third 14:3, of fourth 19; 
width of sternum 2°5, length 3°5 ; length of superior spinner 2. 
Two female specimens in the Museum collection from 
Ceylon. The first, which has been selected as the type, was’ 
taken by Mr. EK. E. Green at Punduloya; the second was 
obtained by Mr. Holdsworth. 
The nest of this spider, which Mr. Green brought with the 
specimen, was found on the trunk of a tree. There are two 
doors set close‘together, with their hinges in contact, and 
consequently opening back to back. These doors, more or 
less inegularly circular in shape, are thin and laminate, and 
consist of small coherent lamelliform particles, which appear 
to be pieces of the epidermis of the leaf of some flowering
