7. Pontellopsis pexa nov. sp. Plate LIV, figs. 11—14. 
Female — length 2,2 mm. 
Seen from above, the body appears of the usual Pontellopsis shape. It is robust, and 
the last thoracic segment is produced into bluntly rounded processes (Plate LIV, fig. 11). The 
cephalic segment and the first three thoracic segments, have narrow bands of short hairs. The 
dorsal surface of the last thoracic segment is covered with short hairs as shewn in the figure. 
The rami of the rostum are long and slender (Plate LIV, fig. 12). 
The abdomen is composed of two segments. The genital segment is long and asymmetrical. 
The distal end of the right side is considerably inflated. The furcal joints are comparatively 
short and are nearly symmetrical. The abdominal segments are without spines. 
The antennules are twenty-jointed. The third to the eighth joints are rather indistinctly 
separated. 
The antennae, mandibles, maxillae and maxillipedes are similar to those Poxtellopsis armata. 
The first four pairs of feet are also similar to those of that species. 
The fifth pair of feet is quite asymmetrical. The exopodite of the right foot is much 
shorter than the exopodite of the left foot. The distal end of the inner margin is produced into 
a strong spine. The apex of the right exopodite terminates in three small teeth. The exopodite 
of the left foot is moderately long and spiniform. There is no inner edge spine and the apex 
terminates in a single point.. The endopodites are asymmetrical and the apex is bifurcate 
(late elV. fig. 14). 
This species has a certain amount of resemblance to Pontellopsis tenutcauda (Giesbrecht), 
but it can readily be separated from that species, or any of the other known members of the 
genus, by the bluntly rounded projections of the last thoracic segment, and by the structure 
of the fifth pair of feet. 
Male unknown. 
Occurrence. — One specimen was found in the plankton collected at each of the 
following two stations. 
Stat. 138. — Stat. 145. 
8. Pontellopsts macronyx nov. sp. Plate LIV, Figs. 1—10. 
~ Female — length 1,97 mm. 
Viewed from above, the body appears moderately robust. The last thoracic segment is 
symmetrical. It is produced posteriorly into pointed processes (Plate LIV, fig. 1). The rami of 
the rostrum are long and slender. 
The abdomen is composed of two segments. The combined length of the abdomen and 
furca is contained two and a half times in the total length of the cephalothorax, from the 
frontal margin to the base of the genital segment. The genital segment is moderately long. It 
is slightly asymmetrical. The proximal and distal regions of the margin of each side are furnished 
with spines. The right distal spine is shorter than the left distal spine. The furcal joints are 
short (Plate EVE, fig. 1).
