endopodite is rather shorter than the exopodite. The joints are of nearly equal length, but 

 the first joint is slightly wider than the second joint. The apex of the second joint is furnished 

 with two finely pointed spines and two setae (Plate LXV, fig. 14). 



The second, third and fonrth pairs of feet are nearly similar to those oï Peltidium intermedium. 



The fifth pair of feet is short and moderately robust. The second joint is furnished 

 with two marginal and three apical setae. The distal marginal seta is moderately stout and 

 the distal portion is clothed with short spines (Plate LXY, tig. 15). 



Male unknown. 



This species can readily be recognised by its oblong ovate body, by the six-jointed 

 antennules, by the arrangement of the setae on the fifth pair of feet, and by one of these setae 

 being stouter than the others. 



Occurrence. — One specimen was found in the washings from dredged invertebrata 

 collected at Station 273, at a depth of 13 metres. 



4. Pcltidium minulum nov. sp. Plate LXY, figs. 16 — 20. 



Female — length .8 mm. 



Seen from above, the body appears comparatively narrow. It is elongate ovate in outline. 

 The greatest width is at the distal end of the cephalic segment and is contained fully one and 

 two-third times in the total length of the animal. The distal ends of the cephalic and thoracic 

 segments are pointed. The segments are produced dorsally in the middle line into triangular 

 projections. The rostrum is moderately large and prominent. The frontal margin is broadly 

 rounded. The genital segment is large and broad. The pointed distal ends of the segment 

 reach to near the middle of the furcal joints. The furcal joints are short and moderately stout. 

 Each joint is twice as long as broad and the middle of the outer margin is furnished with 

 a short seta (Plate LXY, fig. 16). 



The antennules are composed of seven joints. The fifth and sixth joints are very short. 



The antennae, mandibles, maxillae and maxillipedes are nearly similar to those of 

 Peltidium exiguum. The second joint of the second pair of maxillipedes is broad. The terminal 

 claw is comparatively short and is bluntly pointed. 



The exopodite of the first pair of feet is moderately stout. The first joint is much shorter 

 than the second joint. The third joint is very short and is furnished with two rather stout 

 curved claws. The endopodite is considerably shorter than the exopodite. The joints are of 

 nearly equal length but the second joint is much narrower than the first joint. The apex of 

 the second joint is furnished with four setae (Plate LXV, fig. 19). 



The second, third and fourth pairs of feet are similar to those of Peltidium exiguum. 



The fifth pair of feet is comparatively long and slender. The second joint is furnished 

 with two outer marginal. and three apical setae (Plate LXY, fig. 20). 



Male unknown. 



This species can be distinguished from the other members of the genus by the comparatively 

 short and stout furcal joints, by the rather slender fifth pair of feet, and by the arrangement 

 of the setae on the second joint of this pair of feet.
