PYCNOGONIDA—CALMAN. 
45 
half the length of cephalic segment, much wider than long, slightly swollen over base 
of each chelophore. Ocular tubercle conical nearly from the base, not much taller 
than its basal diameter; anterior eyes hardly larger than posterior. 
Proboscis directed obliquely downwards, slightly inflated, conoidal at apex. 
Abdomen almost vertical, cylindrical, blunt. 
Chelophores with scape undivided, palm of chela half as long as scape, movable 
finger with its distal or outer surface greatly swollen for two-thirds of its length, 
but bearing only a very few minute setse. 
Palp an elongate papilla wedged in between liases of chelophore and oviger. 
Ovigers composed of seven segments ; fourth and fifth equal, each more than half 
as long again as third, sixth little more than half as long as fifth, greatly dilated, 
pyriform, its greatest width twice that at the base, pale in colour and soft, set with 
minute recurved setse ; seventh segment forming a small soft papilla on distal surface 
of sixth. 
Legs long and rather slender. First coxa with posterior corner of distal margin 
on dorsal side produced and conical. Second coxa much longer than the other two 
together, with a well-marked gland-tubercle about the middle of its upper surface 
and the distal end produced ventrally into a large acutely conical process which, in 
the last two pairs, carries the genital aperture on its proximal slope near the apex. 
Third coxa with lower distal angle also produced but less acute. Femur and first tibia 
and, less distinctly, second tibia, with three conical tubercles at distal end above, and 
one obscure tubercle on each side below, the lateral line. Opening of femoral 
cement-gland not detected, no projecting duct present. Second tibia with a distinct 
distal fringe of spines below. Propodus with ventral spines increasing in size from 
base for two-thirds of its length, beyond which is a group of smaller spines. Main 
claw about two-thirds as long as propodus. No auxiliary claws. 
Surface of body and limbs smooth and naked, with only a few scattered spinules 
on the legs.
