claws is perhaps, on the average, somewhat weaker, tkougk only slightly so, than in the
species mentioned.
The frontal organ, up per lip and lateral eye s are similar to those
of the preceding species.
Male: —
Shell: — This agréés both in shape and length with the male shell of the preceding species.
With regard to the other organs but little information can be given, as they were in so
damaged and dirty a condition in the only specimen accessible that it was impossible to carry
out a detailed investigation with any certainty. As far as could be seen, the exopodite of
the second antenna, the mandible, maxilla and fifth, sixth and seventh lirnbs seemed to agréé
closely with these organs in the female. The endopodite of the second antenna was very like
this organ in the male of the preceding species.

Description: — Shell: — The shape is somewhat, tliough rather slightly, different
in males and females. — It is oval, with or without a weakly developed posterior corner.
The rostral incisui- is most frequently narrow and comparatively deep, only in exceptional
cases quite shallow. Near the inner edge of the incisur there are two medial bristles situated close
to each other. With rather strong calcification. All the species hitherto known are rather large.
