CRUSTACEA OF THE MEEGTTI AECHIPELAGO. 03 



Stimpson, however, says in his description that the antennse 

 are similar to those of JPiluonnus; but perhaps he has mistaken 

 their real structure, as his specimens were very small. The 

 species lately described and figured by Miers under the name 

 of FseudorTiomMla sulcatifrons, var. australiensis, is also closely 

 allied to this species ; but it seems to differ by its longer and 

 more slender dactylopodites, by the non-emarginate front, and 

 the complete absence of hairs on the wrist (Miers, Zoology of 

 the Voyage of H.M.S. 'Alert,' Crustacea, p. 242, pL xxiv. 

 fig.C). 



Should JPilumnoplax sulcatifrons, Stimps., prove to be identical 

 with Eucrate a finis, Hasw., I should then be inclined to retain 

 the latter name, although of later date than the former, because 

 in both species the anterior margin of the front is transversely 

 Bulcate.

Carcinoplax setosus, Alph. Milne-Edwards, Nouv. Arch, du Museum 

 Hist. Nat. t. ix. p. 267, pi. xii. fig. 2. 



Three specimens (one d , two $ ) were collected at Owen 

 Island. 



The cephalothorax of the largest individual is 7| millim. 

 broad. 



This small species has been found on the shores of Kew Cale- 

 donia and of the island of Banda (Leaden Museum). 



61. Caecinoplax iwtegee, Miers. 



Carcinoplax Integra, Miers, Report on the Zoological Collections made 

 in the Indo-Pacific Ocean during the Voyage of H.M.S. 'Alert,'' 1884, 

 p. 543, pi. xlviii. fig. C. 



Three specimens were collected at Elphinstone Island, two 

 males and one female. 



I am enabled to add some additional remarks to Miers's descrip- 

 tion of this species, as the Mergui specimens are of a much larger 

 size than those he described. The cephalothorax of the largest 

 specimen ( J )is IO5 millim. broad and 7| millim. long; unfortu- 

 nately this specimen has lost both chelipedes. The specimen 

 which was described by Miers was ooly half that size. The front 

 is much deflexed, and divided by a small median triangular incision 

 iuto two lobes ; the margins of these lobes are nearly straight
