endopodite of the fourth pair of feet is also as long as the first joint of the exopodite, but 

 the proximal joint is very short (Plate LX, figs. 22 and 23). The armature of the four pairs 

 of feet does not appear to differ from that of the females of the genus. 



The fifth pair of feet is rather small and is distinctly two-jointed. The proximal joint 

 is comparatively large and is only slightly expanded internally. The apex is narrow and is 

 furnished with three setae. The distal joint is narrowly and irregularly wedge-shaped with a 

 distinctly pointed apex. It is furnished with two outer marginal setae and three inner marginal 

 setae (Plate LX, fig. 24). 



Female unknown. 



It is scarcely likely that this can be the male of either Phyllopodopsyllus bradyi (T. Scott) 

 or Phyllopodopsyllus furcifer G. O. Sars as the size is much too small, and the furcal joints 

 are so distinctly different in shape and proportional length. It may, however, prove on future 

 investigation to be the male of Phyllopodopsyllus minor (Thompson and Scott). The type 

 dissections of Phyllopodopsyllus minor shew no tracé of the tooth-like processes on the inner 

 expansion of the apex of the second joint of the basiopodite of the second, third and fourth 

 pairs of feet. I prefer, for this reason, to regard it as distinct in the meantime. 



Occurrence. — One specimen was obtained from the plankton collected at Station 40, 

 off Pulu Kawassang, Paternoster Islands. 



32. Family Laophontidae. 

 Genus Laophonte Philippi, 1840. 



The members of this genus are readily distinguished by the very feeble exopodite and 

 greatly produced endopodite of the first pair of feet. The endopodite is two-jointed and ter- 

 minates in a very powerful claw. 



Two species belonging to this genus were found in the material collected by the 'Siboga' 

 in the Malay Archipelago.
