 Sea (Czeruiavski) ; Red Sea (Kossmann) ; Seychelles (Chevreux) ; 

 Ceylon, Maldives, Seychelles, Zanzibar, Red Sea (Walker) ; Tuamotu 

 and Grambier Archipelago (Chevreux) ; Algoa Bay, 10 fathoms 

 (Stebbing.) 



Walker's species A. lobata remains obscure. Of the two features 

 which are claimed as distinguishing this species from others, the lobe 

 on apex of 2nd joint of 1st and 2nd gnathopods is present in several 

 other species, and the supposed tertiary cutting-edge in the mandible 

 seems to be only the new mandible forming within the old (cf. 

 Stebbing's figure of A.flindetsi, Challeug. Rep. vol. 29, pi. 118). The 

 lobe on the third joint of the gnathopods is also stated to be charac- 

 teristic and is represented in the figures as rather strong, but this is 

 also the case with the South African specimens of A. vaillantii and 

 cannot be regarded as a distinguishing character. Walker himself is 

 inclined to regard his specimens as immature, and the structure of the 

 mandible confirms him. I am inclined therefore to regard lobata as 

 an immature form of vaillantii.

I have little hesitation in identifying these specimens with Dana's 

 species, appending however a brief description of them. 



Eyes subrotund. Side-plate 1 scarcely produced forwards, 5 largest.
