tion may hereafter prove to be a character o£ very young indi- 

 viduals, similar to what occurs in young specimens of Eriphia 

 IcBvimana. Perhaps these specimens belong to Haswell's Lep- 

 todius granulosus (Proc. Linn. Soc. N. S. W. vol. vi.), but his 

 description is not at my disposal.

Seven specimens were collected at Owen Island, viz. two very 

 young males and five females ; two of the latter are adults. 

 They fully agree with the original description and figure. In 

 the adult females the anterior margin of the arms of the cheli- 

 pedes is armed with a row of four or five strong spines. The 

 species may easily be distinguished by this character from the 

 closely allied Chlorodopsis melanochira, A. M.-Edw., from New 

 Caledonia. In the females the black coloration of the fingers 

 does not extend on the outer or inner surface of the palm, 

 whereas in the adult male it does do so according to Mr. Miers. 

 In the young specimens the anterior margin of the arm is still 

 nearly unarmed, only presenting one or two small acute tuber- 

 cles at the proximal end ; the anterior margin of the front 

 and the orbits are also less spinulose in these young indi- 

 viduals. 



Chlorodopsis pilumnoides has hitherto only been recorded from 

 Singapore and the Philippine Islands.

A male specimen is in the collection from Sullivan Island, 

 and it perfectly agrees with a specimen collected at Djeddah, 

 in the Eed Sea. It is only 10 millim. broad, whereas the
