122 Some Natal Crustacea 
Baker’s description of the carapace suffers somewhat from the loss 
of a line for which one already given is substituted. In Kemp’s 
account, what is said of “the first pair of pereeopods” must refer to 
the first pair of maxillipeds. Our specimen from Isezela, Natal, a 
female 30-5 mm. long, laden with eggs, does not essentially differ from 
Baker’s account of the Australian form. The rostrum does not reach 
beyond the eyes and there are only four median teeth as in some of 
McCulloch’s specimens, and in that which Haswell refers to A. palpalis. 
The telson has the dorsal spines and setz as described by Baker, but 
the truncate apex carries four spines. The three joints of the palp 
of the mandibles are equal, all setose; no cutting plate could be 
perceived. As shown in the figure, the inner plate of the first maxilla 
appears reversed, and such a position of it in the other species may 
have caused Thomson to overlook it. Both of the second perzopods 
have the wrist composed of seven jointlets, with the two preceding 
joints showing only the faintest signs of subdivision into two parts 
each, as proved to be the case with Baker’s specimen (see McCulloch, 
loc. cit.). Yet this is of no use for specific distinction, since Kemp 
finds that exactly the same character may occur in A. palpalis. The 
second antennz agree well with Baker’s account, as also the third 
maxillipeds. 
Mr. Bell Marley records the colour in life as ‘red speckled on pale 
brown, legs banded red, antennz white,” and says that it was found 
‘under large rocks near water’s edge.” 
In another specimen from the same locality, colour ‘“ brown-red 
speckled on grey,” a male, with carapace 13 mm. long and pleon twice 
that length measured round the curve to the apex of ‘the telson, the 
rostrum reaches slightly beyond the eyes. The dorsal teeth are four. 
The endopod of the first maxilliped is apically simple, not bifid. The 
third maxillipeds are very unequal in length. The second peraopods 
show obscurely nine jointlets to the wrist, with the two preceding 
joints pretty clearly subdivided.
