PYCNOGONIDA. 1] 
tubercular process arched towards the extremity of the limb. They occur distally on 
the first coxa, dorsally on the second, where there are two rows, and ventrally on the 
third coxa. Elsewhere there are five rows in which the ventral tubercles are the 
smallest. Between the two rows on the second coxa distally is a rounded tubercle 
bearing no seta. The distal extremity of the second tibia is liberally provided with 
small stout sete not connected with tubercles; its distal fringe is inconspicuous. 
The tarsus is covered with setze which increase in length distally, forming a fringe of 
long and stout sete. The tubercular character of the leg completely disappears on 
this and the succeeding joint. On the propodus there is a scanty supply of minute 
sete dorsally, and ventrally at the proximal end of the joint is a well-developed 
enlargement bearing three spines of moderate strength; the rest of the ventral surface 
is occupied by a band of small but fairly prominent spinous setie. 
A single specimen of this species was taken off the Barrier, lat. 78° 25'40" S., long. 
185° 39’ 6” E. in 300fms. Bottom, mud. ; 
It is an adult female, with the Genital apertures prominent on the second cox of 
all the legs. 
PALLENOPSIS. 
Body slender or robust, distinctly segmented. 
Proboscis cylindrical, ventral in origin, flexibly united to the trunk. 
Abdomen long and slender. 
Chelifori well developed ; scape long, two-jointed. 
Palps reduced to a more or less conspicuous knob. 
Ovigers ten-jointed, present in both sexes, without a terminal claw or denticulate spines. 
Legs with auxiliary claws. A tubular duct occurs in a mid-ventral position on the femora of the 
male. 
Ocular tubercle placed anteriorly on the cephalon, with two unequal pairs of eyes. 
As above stated, the generic definition is much altered from the original of Prof. 
E. B. Wilson (32). Besides the two new species described below, no less than thirteen 
have from time to time been recorded, all of them from a strictly limited number of 
specimens. They are separated by characters which, when committed to paper, do 
not appear as definite as one would like. Nothing is known with regard to the 
variation which may occur within the limits of “a species,” and so it must remain open 
to question whether I have taken the right course with reference to P. hiemalis and 
P. pilosa, Hoek, or not. 
PALLENOPSIS GLABRA. 
Pallenopsis glabra, Mébius (23), p. 184. 
Specific characters :— 
Body comparatively slender, with lateral processes widely separated, and with two small tubercles 
dorsally. 
Chelifori well developed, scape two-jointed, the whole limb minutely scabrous. 
Palps reduced to a conspicuous stump. 
Ovigers ten-jointed, without claw or denticulate spines. 
Legs long, covered throughout with minute spinous sete.
