identical with Philippt's genus Peltidiunï. The description of the exopodite and endopodite of 

 the first pair of feet in the report on the Ceylon Copepoda is erroneous. The endopodite 

 should be exopodite and vice versa. 



Four species, all apparently undescribed, were obtained from the material collected by 

 the 'Siboga' in the Malay Archipelago. 



i. Peltidium falcatum nov. sp. Plate LXIV, figs. 7 — 11. 



Female — length i,i mm. 



Seen from above, the body appears very broad and considerably depressed. It is oblong 

 ovate in outline. The greatest width is at the posterior end of the cephalic segment and is 

 contained 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 median 

 line into triangular projections. The rostrum is very large and prominent. The frontal margin 

 is broadlv rounded. The genital segment is very large and much produced posteriorly. The 

 distal ends of the segment project slightly bevond the end of the furcal joints. The furcal 

 joints are two and one-third times longer than broad. The outer margin of each joint is furnished 

 near the middle with a short seta (Plate LXIV, fig. 7). 



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



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

 those of Peltidium purpureum Philippi. The terminal claw of the second pair of maxillipedes 

 is nearly as long as the second joint. It is moderately stout at the base and contracts gradually 

 to point at the distal end (Plate LXIV, fig. 9). 



The exopodite of the first pair of feet is very slender. The second joint is distinctly 

 longer than the first joint. The third joint is very short. It is armed with one stout and one 

 slender curved claw. The endopodite is shorter than the exopodite. The joints are of equal 

 length, but the first joint is much wider than the second joint. The apex of the second joint 

 is furnished with two stout blunt pointed spines, and two setae (Plate LXIV, fig. 10). 



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



The fifth pair of feet is very small. The second joint is furnished with four outer 

 marginal setae and one apical seta. The fourth outer marginal seta is short (Plate LXIV, fig. 11). 



Male unknown. 



This species can readily be recognised by the very wide body, by the slender exopodite 

 of the first pair of feet, and by the short second joint of the fifth pair of feet. 



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

 collected at Station 226, from a depth of 1595 metres. 



2. Peltidium intermedium nov. sp. Plate LXV, figs. 6 — 10. 



Female — length .Sj mm. 



Seen from above, the body appears moderately broad and rather depressed. It is somewhat 

 quadrangular in outline. The greatest width is near the posterior end of the cephalic segment 

 and is contained one and three-fourth times in the total length of the animal. The distal ends
