identical with Puitippi’s genus Pe/tedium. 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 wzce versa. 
Four species, all apparently undescribed, were obtained from the material collected by 
the ‘Siboga’ in the Malay Archipelago. 
1. Peltidium faleatum nov. sp. Plate LXIV, figs. 7—11. 
Female — length 1,1 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 broadly rounded. The genital segment is very large and much produced posteriorly. The 
distal ends of the segment project slightly beyond 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 Peltedium 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 .87 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
