CBUSTACEA OF THE MEEGUI ABCHIPELA&O. 33 



In two specimens only the last antero -lateral tooth on each 

 side is spiuif orm ; and this probably has also been the case iu the 

 third example, but unfortunately in it these teeth seem to be 

 broken off. In the specimens from New Caledonia, described by 

 M. Alph. Milne-Edwards, the last two antero-lateral teeth were 

 spiniform. Not only is the anterior margin of the arms of the 

 chelipedes armed with more or less acute tubercles, but some 

 are also present on the upper margin. The ambulatory legs are 

 densely covered, along their upper margins, with long yellowish 

 hairs and, as in the Red-Sea specimen described by me some 

 time ago, the upper margin of the meropodites is spinulose and 

 not granulose, as stated by Alph. Milne-Edwards. 



CJilorodius sculptus, a very distinct species, has previously been 

 found in the Eed Sea {de Man), on the shores of the Seychelles, 

 the Samoa Islands, and New Caledonia.

Twenty-five ratlier young specimens of this widely distributed 

 species are in the Collection ; all belong to the typical L. exaratus, 

 M.-Edw. Thirteen were collected at Elphinstone Island Bay 

 (7 d , 6 $ ), six at Owen Island (3^,3$), and six at King Island 

 Bay. One of the Elphinstone-Island female specimens is infested 

 with a Sacculina.

Two specimens ( c? $ ) were collected at Owen Island. The 

 cephalothorax of the larger specimen, the male, is 16| millim. 

 bruad ; whereas the female individual, which is already carrying 

 eggs, is scarcely 10 millim. broad. According to Milne-Edwards, 

 this species, however, attains a breadth of 20 millim.
