I have only to add to the quoted descriptions that the posterior 

 half of the upper surface of the cephalothorax is also punctate, 

 so that the whole upper surface is punctate. This species pre- 

 sents a singular resemblance to Xantlio nudipes, Alph. M.-Edw. 

 (I. c. p. 197, pi. vii. fig. 5). In this latter form, however, which 

 has the fingers of the cbelipedes pointed and not at all excavated, 

 the distance of the orbits measures only a third of the breadth of 

 the carapace, whereas in Leptodius nudipes the cephalothorax is 

 scarcely twice as broad as the distance of the orbits. 



Leptodius nudipes, Dana, has been recorded from the Strait 

 of Balabac, New Caledonia, New Zealand, and the Sandwich 

 Islands.

Three specimens (1 c? , 2 § ) of this rare species were collected 

 at Owen Island. They agree perfectly with the original descrip- 

 tion and with the figure quoted. 



The cephalothorax of the largest specimen ( c? ) is 12 millim. 

 broad, and the smaller female, which is already provided with 

 eggs, is only 10 millim. broad. According to Dana, however, 

 this species attains a breadth of more than 10 lines. 



The rare Leptodius cay^pes has hitherto been recorded, so far as 

 I know, only by Dana and by Stimpson from the Benin Islands. 



26. Leptodius, sp. 



The Collection contains two very young specimens, namely, 

 a male individual found at Elphinstone Island, and a female from 

 Owen Island, which are closely allied to Leptodius exaratus, but 

 which differ from that common species by the hands being covered 

 with small granules. The cephalothorax of the male specimen is 

 scarcely 9 millim. broad, that of the other scarcely 10 millim. 

 As regards the shape of the carapace, these examples resemble 

 very well Leptodius exaratus, the antero-lateral margins being 

 armed with four teeth, but the upper surface is somewhat 

 minutely granular anteriorly. The cbelipedes of the male are 

 unequal, those of the female almost equal ; the granules, with 

 which the outer surface of the hands is provided, are more 

 distinct in the male than in the female. 1 do not venture to 

 give a new name to these specimens, especially as this granula-
