90 PERCY SLADEN TRUST EXPEDITION 



about the apex of the sixth joint in the third perseopods the serrate spines are more 

 numerous. The third and fourth pairs have a minute character bringing the species into 

 accord with P. latifrons. In that species Professor Sars notices, in speaking of the third 

 and fourth perseopods, that " the auditory cilium characteristic of these feet is inserted 

 in advance of the middle of the sixth joint's outer margin and less strongly developed tban 

 in the genus Apseudes." His figures of the third perseopod of Apseudes robustus show 

 that the cilium in question is there very near the base of the joint. In our Parapseudes 

 it will be seen that, though varying in position on the different limbs, it is always at a 

 considerable distance from the base of the sixth joint. 



The presence of the pleopods could not be made out. 



Both branches of the uropods appear to begin with an ill-defined minute joint, perhaps 

 only a cuticular fold, followed in the inner branch by eight unequal but fairly long joints, 

 and in the outer by three such joints, most of the joints carrying long setse. 



Length, in bent position, 2 mm. Hansen's Apseudes intermedins measured 2 - 3 mm., 

 for females with half-developed marsupium, therefore perhaps not full-grown. Our specimen 

 contained eight large eggs in the marsupium, and was probably fully adult. It resisted 

 efforts to straighten it out for exact measurement. 



Locality. Egmont, breakers on reef edge. 



The specific name alludes to the prominence of its setose furniture.

An ovigerous specimen, a little under 2 mm. in length, was taken at Zanzibar by 

 Crossland. As no male accompanied it, the identification with the Mediterranean species 

 can only be regarded as conjectural.
