TRAPEZIA CYMODOCE. 177 



description given by Mr. Heller ; the breadth of the carapace 



is 9'/3 mm. 



10. Trapezia digitalis Latr. 

 Heller, 1. c. pag. 352. 



Six very beautiful specimens (3 cf and 3 9) are iu the 

 collection. 



They agree entirely with the quoted description , but I 

 will remark that the lateral margins of the carapace , though 

 not being armed with a lateral tooth, are however pro- 

 vided with a very small scarcely visible incision , which is 

 to be seen only by a magnifying glass, even in the adult 

 specimens. — Our specimens are of a very dark blackbrown 

 colour , but the lower part of the outer and iuner surface 

 of the hands, as also the fingers are of a light yellowish 

 gray colour and the lower surface of the ambulatory legs 

 are marked purplish red.

 of Nat. Hist, for Nov. 1878, pag. 409. 



There are sixteen fine specimens of this species (8 cT 

 and 8 9) in the collection , which agree entirely with the 

 description , given by Mr. Heller. As has been shown 

 already by Mr. Miers in his note on some Crustacea from 

 the Gulf of Akaba (1. c), this species may be characterized 

 by the distinct lateral tooth of the carapace , the distinctly 

 developed frontal teeth , the blunt tubercle on the inner 

 angle of the carpopodite of the anterior legs and the upper 

 part of the outer surface of the hands being covered with 

 hairs , which characteristics are not found in the other 

 species. — The anterior margin of the arms is armed
