labium, rounded off on their outer and pointed on their inner extre- 
mities. 
Labium very short, broad, and somewhat semicircular in form. 
Sternum of a somewhat triangulated heart-shape. 
Abdomen oval, cylindrical; its upper extremities projecting over 
the spinners. 
CEPHALOBARES GLOBICEPS, 0. sp. (Plate XLIV. fig. 4.) 
Male adult, length 17 line. 
The cephalothoraz, falces, maville, and labium are of a brown 
colour tinged with yellowish; the former is clothed with a few pale 
hairs; and the normal grooves and indentations are amost obsolete, 
the caput being apparently the elevation of almost the whole cepha- 
lothorax ; in fact this part seems to have run entirely to caput, 
which is broad, rounded, and so considerably elevated and promi- 
nent that the clypeus is overhung and partly underneath the fore 
part of the caput; the cephalothorax thus reminds one of some of 
the species of Hrigone (Walckenaera), especially W. humilis (Bl.) 
and W. affinitata (Cambr.). 
The eyes occupy a large area, being spread out over the fore part 
of the caput in the form stated in the “generic characters’’ above ; 
those of the fore central pair are dark-coloured and slightly the 
largest of the eight ; those of the lateral pairs are the smallest, and 
with those of the hind central pair are pearly white. 
Legs pale yellow, broadly banded with bright orange-red, and 
furnished sparingly with short hairs. 
Palpi short, ot a yellow-brown colour, except the digital joints, 
which are dark brown; the cubital is shorter than the radial joint, 
which is large, expanding forwards, and somewhat produced at its 
upper extremity over the base of the digital joint, which last is of a 
short oval form ; the palpal organs are well developed, but not very 
complex, being very similar in general form and structure to those 
of many typical species of “‘ Theridion.” 
The abdomen is of an oblong or somewhat oval-cylindrical form, 
and does not project over the base of the cephalothorax ; it is spa- 
ringly clothed with hairs, and is of a pale yellowish-white colour ; the 
upperside has an indistinct pattern, and the sides are also marked 
with longitudinal striations of a deep brown colour ; the hinder part 
of the abdomen is bluff and abrupt, and projects over the spinners ; 
this bluff portion has four rather conspicucus dark shining tubercular 
patches forming nearly a square, whose area is tinged with pinkish 
red ; the underside and around the spinners are also strongly tinged 
with the same colour. 
An adult male of this Spider was contained in a fine collection of 
Araneidea kindly made for me in Ceylon by Mr. G. H. K. Thwaites, 
during the past year. Although generically closely allied to Theri- 
dion, it was impossible to include it satisfactorily in that genus; the 
shortness of the legs, the extraordinary form of the caput, as well as 
differences in the structure of the more ordinary generic parts, made 
it necessary to construct a new genus for its reception.
