PYCNOGONIDA. 43 
lateral band of some width, almost completely bare of them. On the two tibize the 
same arrangement of the sets occurs, except that along the middle of the bare band 
there is a narrow band of sete two or three wide. The distal fringes of the femur and 
first tibia are not conspicuous, but that of the second tibia is formed of stout spines 
chiefly on the ventral surface. The tarsus is a very small joint, and forms a cup-like 
socket for the propodus (fig. 1b); it is thickly covered with small spines, and its distal 
fringe is well developed, especially ventrally, where it is formed of very stout spines. 
The propodus is covered thickly with stout setee with only an irregular vestige of the 
bare band found on other joints; it is slightly curved, and its ventral side bears 
proximally four or more very stout spines, of which the first is the smallest; the rest 
of the margin is taken up with setz small, but larger than the average ; close to the 
terminal claw is a group of large sete, one of which at least is a rather prominent 
spine. The extremity of the joit is oblique, and forms a rounded spinose projection 
or heel beyond the origin of the stout claw, which, with its two powerful auxiliaries, 
arise from a common investment. 
The single adult specimen captured is a female, and the Genital apertures are 
conspicuous on the second coxa of each leg. Five smaller specimens were, however, 
taken at the same time and place, varying in size from 9°5 mm. to 18°5 mm. over all. 
These present several differences of no small importance. The proboscis differs slightly 
in form, being more tapering the smaller the specimen, and it is also more rigidly 
articulated to the body ; in none of them is it movable through so large an angle as 
in the adult. The chelifori are proportionally the same size as in the adult, but a 
perfect chela is developed. This is small and feeble, the fingers curved like a pair 
of callipers, and devoid of teeth. On the body the dorsal ridges are raised into a 
more definite median point, and the tubercles which give an angular appearance to the 
lateral processes and first coxee of the adult are now rather more prominent and carried 
on to other joints. The pre-abdominal tubercle is a very variable structure, and is 
sometimes prominent—in one case almost absent. The palps do not call for any fresh 
description, but the ovigers show several interesting stages in their development (figs. 
1c-1f). In the smallest specimen only the merest vestige of such an appendage exists. 
In the next specimen four joints as such may be distinguished, the last one showing an 
indication of future segmentation. In another, six joints are fairly well established, 
the penultimate one showing traces of another division. In the largest of the 
immature specimens the oviger possesses the full number of ten joints, but they are 
very small, and the four terminal ones are only indicated and not clearly developed. 
Cape Wadworth, Coulman Island, 8-15 fathoms. Bottom: stones. Several 
adult specimens were taken by the ‘Frangais’ off the west coast of Graham’s Land, 
and one was taken by the ‘ Scotia.” The examination of Professor Pfetfer’s Anumothea 
grandis trom South Georgia has established the identity of this species beyond all 
question.
