It is clear, I think, that the beautiful specimen obtained by Mr. 
Bell Marley at Durban belongs to the species represented by Herbst 
in his plate 31, fig. 1, but his text covers more than one species and 
the name he gives is here unavailable. The account, however, which 
Fabricius gives of his Pa/inurus ornatus is quite suitable to the Natal 
specimen, for which also the specific name is highly appropriate, so 
that I am unwilling to accept Ortmann’s verdict that it ought to be 
dropped. As Fabricius says, the segments of the pleon are smooth, 
altogether without a furrow, though this is true also of P. polyphagus 
(Herbst), seemingly near to ornatus but distinct from it. 
Mr. Bell Marley’s account of the colouring in the freshly captured 
animal is as follows: ‘‘ The carapace is a really dark turquoise blue, 
the spines coral red, with bases orange in the larger spines, the [pleon] 
segments are green (sage) with brown, at the sides are cream spots ; 
about head much pink with white, brown and blue marks; the 
antenne light red at head and ending in brown and dark brown ; legs 
marbled brown and yellow, toes red.” This description, dated 31st 
July, 1917, is still in many respects applicable to the specimen as 
received in Tunbridge Wells, September 21st. But the dark 
turquoise blue of the carapace has taken something of a greenish
