GEORGE HODGE ON THE PYCNOGONOIDEA. 281 
Report on the Pycnogonoidea, with descriptions of Two New 
Species. By George Hodge. 
Tue Pyenogons dredged during the expedition belong to four 
genera—Pycnogonum, Phoxichilidium, Pallene, and Nymphon. 
Of the latter, seven species were taken, one of which is new to 
science (NV. brewrostre Hodge,*) and two have not been 
recorded as British, MW. hirtum and N. brevitarse, although 
specimens of the new species, and also of those locally new, had 
previously been taken at Seaham, both by inshore dredging, and 
from the fishing lines. Only one individual of the genus 
Pallene was taken, and that a new species (P. attenuata, 
Hodge). 
The rarity of the male Nymphons is singular, none were obtained 
during the expedition, although the number of females was con- 
siderable (23); as a general rule this is found to hold, whilst in 
the case of Pycnogonum, the males are quite common, and the 
females rarely seen. 
PALLENE ATTENUATA, n. sp., Hodge. (Pl. XV., figs. 1-5). 
Rostrum thick, constricted at the base, swelled near the 
middle and rounded at the apex. Legs long, sparingly 
hispid; first, second, and third joints short, the second the 
longest; fourth rather stout, and as long as second and 
third united; fifth and sixth slender and about the 
length of fourth ; seventh very short; eighth convex on 
outer margin, straight on inner, with a few short hairs 
scattered along both margins. A single claw at the 
extremity, which when pressed against the limb reaches 
to junction of seventh joint. Foot jaws long and slender 
projecting considerably beyond end of rostrum. Anterior 
portion of thorax attenuated, and advanced to nearly on a 
line with the tip of rostrum, where it slightly bulges, 
and gives origin to foot jaws; immediately behind which 
is seated the oculiferous tubercle, which is long and narrow. 
Abdomen long, rounded at apex, slightly tapering to 
* The new species described in this paper were characterised in a report presented to the 
Cambridge meeting of the British Association.
