20 DR. J. G. DE MAN ON THE PODOPHTHALMOUS 
22 millim.; the legs of the second pair are about twice as long 
as the bap helonorae measuring 58 millim. 
Mr. Miers presumes that this species is identical with Naswioides 
hirta, A. Milne-Edw., from Zanzibar; I think he is right. 
As Naxia (Nasioides) Petersii has been observed on the 
coast of Mozambique and at the Amirante Islands, it would 
appear to occur throughout the whole northern Indian Ocean.

Three specimens are in the Collection, viz. one adult female 
provided with eggs, found at King Island Bay, and a smaller 
sterile female and a very young male from Elphinstone Island. 
The cephalothorax of the adult specimen is 54 millim. long 
(the rostrum included) and 41 millim. broad (without the lateral 
spines). It belongs to that common variety in which the rostrum 
consists of two long and straight spines that are each provided 
with a short, exterial, obliquely directed accessory spine at the 
base. The upper surface of the carapace is granular, nowhere 
spinose. 
Schizophrys aspera has been recorded from Zanzibar (Ge: 
Edwards), Madagascar (Milne-Hdwards), Mauritius (White), 
the coast of Malabar (JfiIne-Edwards), Borneo (Dana), Torres 
Strait (Haswell), New Caledonia (Milne-Edwards), Navi- 
gator Islands (Milne-Edwards), and Japan (de Haan and 
Stimpson). 
This species may thus be said to occur throughout the whole 
Indo-Pacific region.
