Carpenter — Torres Straits Pycnogonida. 555- 



where the genital aperture is situated ; the femur is once and two- 

 thirds as long as the coxal joints taken together, somewhat swollen 

 centrally in the female (containing eggs in the specimen examined), 

 cylindrical in the male, in which sex (fig 2) it has a distal conical 

 process bearing spines ; there are also distal spines in the female^ 

 and a few long hairs in both sexes. The first tibial joint is some- 

 what shorter than the femur, it bears numerous hairs and spines,^ 

 and, like the femur, has a distal conical process in the male ; the 

 second tibial joint is somewhat longer than the femur (shorter 

 relatively than in P. austraUensis), slender, cylindrical, and very 

 hairy, bearing a few stout spines at its distal end (fig. 6). The 

 tarsus is very short, armed with a few strong spines ; the propodua 

 (fig. 6) is about six times as long as the tarsus, moderately arched 

 with three strong spines beneath its base, and numerous smaller 

 ones beneath the rest of its extent ; it bears a strong claw about 

 three-fifths its length. (None of the spines on the legs are toothed 

 like those of P. aitstraliensis.) The four pairs of ambulatory leg& 

 are of about equal length. 



The smooth spines on the false legs in this species are, I believe, 

 peculiar among the Pallenidse, and seem to indicate a transition ia 

 the Phoxichiliidse. 



Family.— EURYCYDID^. 

 Genus. — Ascorhynchus, Sars. 



In a recent list of the genera of the Pycnogonida (7), Schimke- 

 witsch states his opinion that this genus should be sunk in Eurycijde, 

 Schiodte [Zetes, Kr.). Sars (6), however, points out that the 

 absence of a distinct scape to the proboscis in Ascorhynchus and 

 other structural characters require their separation.

Proboscis narrowly flask-shaped, two-thirds as long as the rest 

 of the body, and reaching when folded beneath beyond the hinder 

 edge of the second trunk segment. Oculif erous tubercle prominent,, 

 conical, and pointed. A dorsal spinous process at the junctions of 

 the segments, and a prominent spine at the hinder end of the last 

 trunk segment. A dorsal spine at the extremity of each lateral
