1915. | F. H. GRavELY : Notes on Pedipalpr. 385 
First legs—Nearly a quarter as long again as body. Coxa 
terminating behind base of trochanter of arm. Femur about three 
quarters length of patella, about as long as tibia. Tibia about a 
quarter as long again as foot. Foot about ten times as long as 
deep, deepest at end of metatarsus. Second metatarsus scarcely 
as long as sum of five proximal tarsal joints, about half as long 
again as terminal tarsal joint. First tarsal joint slightly shorter 
than any of the succeeding four. 
Fourth legs.—t,ike those of male. 
Tail.Long and slender, about six times as long as deep. 
Basal joint nearly twice, second scarcely more than once as long 
as deep. Separation of third and fourth joints obscure. 
Colour of both sexes.—Pale reddish brown, the abdomen and 
legs faintly greenish. 
Length —o about 35,2 about 3:0 mm. The arms of the 
male show this species to be closely related to Schzzomus (s. str.) 
crassicaudatus from Ceylon; but its thoracic terga have the struc- 
ture characteristic of the subgenus Tvithyreus. 
The distinctive features of the arms are fully developed in large 
specimens only. ‘They are scarcely distinguishable in small ones, 
which are often most difficult to distinguish from immature speci- 
mens of the next species. 
Schizomus (Trithyreus) buxtoni, n. sp. 
Localitves.—Polonuruwa, North-Central Province, Ceylon 
(several oo, 2 2; under bricks, many under leaves); Min- 
neriya, North-Central Province (30); Sigiri, Central Province 
(many 70, 9? @). 
@. Cephalothorax.—Eye-spots absent. Cephalic sternum 
slightly longer than wide. 
Arms.—Slender and of moderate length, without distinctive 
tubercles or spines. Trochanter with lower margin distinctly con- 
vex, anterior angle obtuse and more or less rounded with a small 
spine on the inner side behind it, anterior margin practically 
straight. Femur slender, with free ventral margin about equal tc 
anterior margin of trochanter. Claw about half as long as upper 
margin of tarsus. 
- First legs.—Very slender, about one and a half times as long 
as body. Coxa terminating behind base of trochanter of arm. 
Femur much shorter than patella (7: 9), slightly longer than tibia, 
much longer than foot (7:5). Second metatarsus about as long as 
five succeeding tarsal joints, which increase regularly in length 
from basal to distal. 
Fourth legs—Femora fully two and a half times as long as 
deep. 
Tatl.—Somewhat like that of S. suboculatus, but the disc 
broader and more evenly rounded behind, with the sides more 
convex distally—sometimes almost circular or even squarish. 
When seen from the side it lacks the profound dorsal excavation 
seen in Hansen and Sérensen’s figure of that species.
