STUDIES IN AUSTRALIAN CRUSTACEA— McCULLOCU. 59 



tions or cilia, three on both upper and lower borders, and one 

 down the middle on either side. These joints are more com- 

 pressed and broader in the last pair than in the preceding ones. 



Ground colour yellow, but the anterior half of the carapace, 

 the arms, wrists, and upper parts of the hands closely covered 

 with red dots, which give them a pink colour. A large heart- 

 shaped carmine spot on the middle of the back. Lower half of 

 the hand white. On the legs the red dots combine to form a 

 darker shade. 



This species is very similar to E. crenata, de Haan, but the 

 absence of teeth on the antero-lateral borders at once distin- 

 guishes it. With further material, it may prove that this is 

 but the adult form of one of the other species known from the 

 Queensland coast, but for the present it is deemed best to figure 

 it under a new name. 



Moreton Bay, Queensland, in shallow water. Three specimens ; 

 the largest being 53 mm. and the smallest 46 mm. wide ; col- 

 lected by Mr. W. Hamilton, after whom the species is named.

I have compared four specimens of this southern form, includ- 

 ing one from Mr. Grant's collection, with a specimen of T. ungui- 

 formis from Japan. They differ from it in having the length of 

 the body equal to its width, and the front much longer and 

 differently shaped. The dactyli of the ambulatory legs also 

 appear to be much broader. Though I think it probable that 

 an examination of further specimens will show these characters 

 to be constant, and therefore of specific value, I prefer for the 

 present to regard them under a varietal name only. 



Length of specimen figured (a female), 15 mm.

A large specimen from Moreton Bay agrees perfectly with the 

 above figure and description.
