A male specimen, taken by Mr. Bell Marley at Vetch’s Pier, 
Durban, last year, has a carapace measuring 20 mm. in length and 
about 16 mm. in width, therefore much smaller than the specimens 
described by M*Leay and Krauss. The pleon answers to the figure 
given by the latter, being seven-segmented, but with the median 
segments perhaps immovable. Krauss says that this species is never 
overgrown with marine organisms, and the present specimen answers 
to that statement, but, whereas M°Leay says that ‘the shell of this 
species is without hairs,” here the numerous tubercles which he 
describes are conspicuously furnished with groups of sete, which 
probably enable it to dispense with alien growths. The brown spots 
are still visible all over the under surface and in some other parts of 
the specimen.

A male specimen from Isipingo, Natal, has been sent me by 
Mr. Bell Marley. It was taken on seaweed, and some of its numerous 
curved setze were furnished with the weed, faded but greenish. Its 
length in the middle line is 15 mm., or 17 mm. if extended to a point 
between the tips of the horns. The breadth between the tips of the 
penultimate lateral teeth of the carapace is 12 mm. The size is 
therefore rather larger than that given by Krauss, but the proportions 
do not materially differ. Krauss states the colour to be yellowish- 
brown; Mr. Bell Marley records it as green. In other respects it 
closely agrees with the description and figures supplied by Krauss.
