CRUSTACEA.

Feejoe Islands. 



Length of carapax, seven lines; greatest breadth, thirteen and one- 

 half lines; ratio of length to breadth 1 = 1-93, or nearly to 2. The 

 colour is red, excepting a white band to the tarsus just anterior to 

 the claw which is brownish black. The surface is polished and 

 smooth ' The areolet 1 M is convex, and so the front margin of 2 M 

 to the right of 1 M; but 1 M fades into 2 M, and the latter is hardly 

 distinct behind. A large areolet corresponding to 2 L, 3 L, is the only 

 distinct one in the anterolateral region, although a depression extends 

 inward from the limits of the penult tooth. The upper and lower 

 mar-ins of the hand are parallel, and the fingers are short. There is 

 no trace of a tubercle at the external angle of the orbit ; the first lobe 

 of the anterolateral margin has a straight margin, and is but slightly 

 divided from the second lobe. 



Genus ACT^EA, I)e Hamu 



Eegio carapacis postka plana, cmtero-laieraU* frontalisqw deelives. Ov- 

 inia Tdatu externa non mierrwpta. Artmdus antennarum externarum 

 1 mus frontem attingens. 



Posterior part of carapax flat, the frontal and anterolateral regions 

 rounded and much inclined. Orbit not interrupted by a hiatus at 

 the external angle. First joint of outer antennae reaching the front 

 and affixed to it. 



This genus is closely allied to Actaeodes, the difference consisting in 

 the character of the fingers; and in some instances it is difficult to 

 determine whether the fingers are pointed and not excavate, owing to 

 the transitions between the two genera. It differs from Zozymus in 

 the pointed fingers, and also in not having the eight posterior legs 

 cristate.
