THALAMITOÏDES TRIDENS. 99 



Chlorodopsis spinipes , Alph. Milne Edwards, 1. c. pag. 

 23Ü, pi. Vm, fig. 6. 



A single female specimen, with the carapace 8 mm. broad, 

 is in the collection. 



Etisus laevimanus Rand. 



Four male and eight female specimens were again col- 

 lected ; in some specimens the surface of the carapace is 

 ornamented with more or less numerous dark spots, more 

 or less distinctly marked , [Etisus maeulatus Heller) , but 

 in other individuals these spots are quite wanting , the ca- 

 rapace being coloured with some large dark spots. The 

 largest specimen , a male , has the carapace 36 mm. broad. 



Thalamita savignyi Alph. Milne Edw. 



In all our specimens , ten males and five females , 

 the surface of the carapace is covered with a dense pubes- 

 cence of very short hairs. In one adult male there are 

 only three spines on the left antero-lateral margin, but 

 there are five teeth on the right, the fourth of which is 

 rudimentary.

A male and a female specimen provided with eggs are 

 collected , as I think , for the first time in the Red Sea ; 

 our species is thus distributed throughout the whole Indo- 

 Pacific region , being found also on the shores of Mada- 

 gascar and Upolu. The breadth of carapace of the fe- 

 male (the distance of the external orbital angles) is only 

 10^2 mm.
