The outer uropod is a little shorter than the inner and bears 
long setae on its outer, as well as on its inner margin; it is a little 
more than three times as long as broad. Tie telson reaches about 
to the apex of the inner uropod; it is deeply sulcate above with 
two pairs of dorso-lateral spinules and in the form of its apex 
resembles P. incisus. 
This species is, I believe, the smallest known Macruran. It is 
smaller even than P. sabsechota, Kemp, the largest individual in 
the collection, an ovigerous female, being slightly less than 7°5 
mm. in total length. The eggs are comparatively large for such 
a small species; when not eyed and to all appearances freshly 
extruded they are about 0°34X0'27 mm. in longer and shorter 
diameter; when fully eyed and ready to hatch they measure about 
0°48 X 0° 36 mm. 
Pontophilus lowist is perhaps distantly related to P. bidentatus, 
de Haan ', and P. japonicus, Doflein®, but from both these species 
it differs conspicuously in the form of the carapace and in the 
presence of a series of spines on the outer edge of the antennal 
scale. 
The colouring of the species differed considerably in specimens 
from different localities. Individuals found on a muddy bottom 
were for the most part densely pigmented with grey and brown, the 
last abdominal somite and taii-fan being colourless except for a dark 
transverse band on the latter. Specimens from sandy ground were 
much lighter in colour, often quite pale and sometimes with one or 
two transverse brown bands. In one example from this type of 
bottom the pigmentation is very peculiar, the carapace being deep 
amber brown, the abdomen white with transverse bars of brown 
on the fifth somite and tail-fan and the antennules bright red. 
2074-51 Port Blair, Andamans, 3-12fms. S. Kemp. 69, 4°5-7°5 mm. 
Specimens were found off Ross I. and in various other parts 
of the harbour, but were most abundant at the inner end ona 
muddy bottom. The types of the species are numbered 9074/I0 
in the Indian Museum register. 
With this species I have associated the name of Mr. R. F. 
Lowis, Deputy Superintendent of Port Blair, to whom I am much 
indebted for assistance during my visit to the Andamans.
