. REPORT ON THE PYCNOGONIDA, 81 



Observations. — This species is in all probabilitj- nearly allied to Pcdiene longiceps, 

 Bohm (Sitzungsberichte der Gesellsch. Naturf. Freunde in Berlin, 1879, p. 59). However, 

 as no figure of Bdhm's species has ever been published, and as the description of it 

 cannot be entirely applied to my specimen, I thought it safer to consider, and to describe 

 this as a new species. 



Pallene longiceps, Bohm, has rudimentary two-jointed palpi, and a short and blunt 

 oculiferous tubercle. Moreover, the form of the denticulated spines of the ovigerous 

 legs of the present species is different from the form described by Bohm for his Pallene 

 longiceps. The latter species is from Japan, whereas my Pallene languida was obtained 

 in the vicinity of Melbourne.

This species has been described and figured by Kroyer {lac. cit.), and again by Bohm 

 {loc. cit.). It may not, however, be considered superfluous to publish new figures ; those 

 of Kroyer are in general highly characteristic, but they are, as regards the details, not 

 very exact ; from Bohm's figure, which has been drawn on much too small a scale, 

 nobody, I think, would recognise the species. 



The description given by both authors is nearly correct. The basal joint of the 

 mandible reaches farther than the tip of the proboscis ; it shows dorsally a little 

 beyond the middle a slight angle, furnished with a row of stronger hairs : therefore 

 the joint seen from the dorsal surface seems to be divided into two. Eudiments 

 of palpi are present in the form of rounded knobs on both sides of the cephalic 

 segment. The ovigerous legs of the full-grown animal are ten-jointed ; I have figured 

 joints six to ten in fig. 3. The sixth joint shows a wreath of short strong sjjines imme- 

 diately before the articulation with the seventh joint. The seventh to the tenth joints are 

 armed with curved spines and strong hairs, but no denticulate spines at all are present. 

 These last five joints of the ovigerous leg are very curiously bent in the form of an S, as 

 has been correctly observed and drawn by Kroyer. The legs are comparatively stout. The 

 only specimen of this species brought home by the Challenger is a male, with rounded, 

 rather large genital openings, which, as far as I could ascertain, are present only on the 

 ventral surface of the second joint of the two hindermost legs. The fourth joint of the 

 leg is more than twice as long as the second, and not inconsiderably swollen in the 

 Challenger specimen ; ventrally a little in front of the middle it is furnished with a 

 distinct and comparatively strong tubular process, which in all probability communicates
