The unique example (a female nearly adult) was obtained at the Moluccas, Amboina, 
in 100 fathoms. 
Perhaps the nearest ally to this interesting species is the Naxia ( Naxioides ) robillardi, 
Miers, 1 described from a specimen dredged in 30 fathoms at the Mauritius ; on account 
of the strongly divergent rostral spines this species may be regarded as intermediate 
between Naxia aud the genus Hyastenus. 
Naxia hirta (A. Milne Edwards).

An adult male was dredged in 1 5 fathoms, at Samboangan. In the disposition of the 
spines and tubercles of the carapace, structure of the orbits, antennse, and legs, it 
very closely resembles the type of Podopisa petersii, as figured by Hilgendorf, 2 from 
Mozambique ; the chelipedes are, however, somewhat more slender. The rostrum, in the 
adult (which in Hilgendorf’s specimen was broken), is of moderate length, with the 
spines at first subparallel, but slightly divergent from the accessory spines, which are 
placed at some distance from the distal extremity ; the rostral spines are themselves not 
much more than one-thircl the length of the carapace : —

2 Dr. F. Hilgendorf has, according to Dr. E. von Martens (Crust, in Zool. Record, 1878, p. 17), himself recognised 
the identity of the genus Podopisa with Naxioides, which is not to be distinguished from Naxia, Milne Edwards. 
But it is possible, I think, that Hilgendorf s species may yet prove to be distinguishable from Naxia hirta. In all the 
specimens I have examined, the carapace (as in Dr. Hilgendorf’s figure), is much more tuberculated than in Naxia 
hirta , ye figured by A. Milne Edwards, the rostral spines are longer, and the posterior spine of the carapace shorter 
than in that figure..
