IgI6. | S. Kempe: Notes on Crustacea Decapoda. 405 
The first peraeopods areas described by Borradaile ; the chela 
resembles that of H. vitiata, the fingers being shorter than the 
palm and meeting only at the tips when the claw is closed. The 
second legs are very slender, reaching beyond the antennal scale 
by nearly two-thirds the length of the carpus; the merus is in- 
distinctly divided into 13 or more segments, while the carpus is 
composed of from 21 to 24 segments. The last carpal segment is 
the longest, about equal in length with the palm and one and a 
half times as long as the fingers. 
Of the remaining pairs of the peraeopods the third is the long- 
est reaching beyond the antennal scale by almost the entire length 
of the propodus. In each pair the merus bears conspicuous teeth 
externally near the lower border: 5 in the third pair, 5 or 6 in the 
fourth and 3 or 4 in the fifth. The posterior edge of the propodus 
is set with fine setae and some seven or eight very slender spinules 
The toothing of the dactylus is characteristic. Asin H. vittata it 
bears 3 or 4 teeth on its posterior margin which increase in size 
distally ; the actual apex of the dactylus does not, however, take 
the form of a tooth, comparable to the others, but is extremely 
slender and, at the base, less than half the breadth of the adjacent 
tooth of the marginal series. 
The abdomen, telson and uropods do not appear to differ in 
any marked degree from those of H. vittata. 
The three specimens obtained are all ovigerous females; the 
largest is about 2r mm. in length. 
The colouration of living specimens is striking, the entire 
carapace and abdomen being marked with longitudinal stripes 
composed of small bright red chromatophores. On the carapace 
at the base of the rostrum the first three pairs of lateral stripes 
meet in the middle line. The three succeeding pairs are strictly 
longitudinal, but beneath them the striping on the carapace is 
oblique. In the middle of the abdomen there are about twenty 
longitudinal stripes. The eyestalks are heavily blotched with red; 
the antennules and antennae are transparent with a faint yellow- 
ish tinge; the third maxillipedes and all the legs, except the second 
pair, are conspicuously banded with red. The tail-fan is dotted 
with red and the eggs are sage green. In colour, therefore, the 
species bears a striking resemblance to Hippolysmata vittata and 
H. dentata, but lacks the transverse bands on the abdomen that 
are found in the former of these species.

The three specimens were all obtained in a single haul of the 
net on rough ground in the southern entrance to the channel off
