RATHBUN— MARINE BRACHYURA 219 



The outer angle of the basal antennal joint is less advanced than the lobe at the inner 

 angle of the orbit. 



Wrists faintly divided into 3 or 4 fiat lobules. The granules of the hand show a 

 tendency to a longitudinal arrangement. Fingers broad with sharp edges, grooved, not 

 gaping ; dactylus with spinules on basal half of upper margin, a large shining tooth at base 

 of cutting edge, succeeded by 2 denticles ; 2 denticles on basal half of immovable finger ; 

 tips crossing, that of the dactylus within the other and curving inward. Granules on the 

 legs sharper than on the carapace ; hairs more numerous ; carpopodites longitudinally 

 grooved. According to previous descriptions, antero-lateral lobes are less strongly marked 

 in large specimens.

Carapace moderately convex, posterior third flat ; antero-lateral margin much longer 

 than postero-lateral, which is concave. Surface broken into many small granulated lobules 

 separated by smooth, naked interspaces; from each granule arise several long, soft, yellow 

 hairs forming a coat which only partially conceals the areolation. Mesogastric region 

 divided into 6 lobules, the largest is the anterior, which is wider than customary in Actcea 

 and somewhat diamond-shaped ; on each side of its posterior end there is a small lobule ; 

 behind each of these, another ; and behind these a transverse lobule. Protogastric region 

 divided by a longitudinal curved furrow into a large inner lobule twice as long as the 

 small outer one. Cardiac region divided longitudinally in two. Intestinal region covered 

 with many small islets, the limits of which are not always well defined. Antero-lateral 

 margin divided into 4 lobes besides the orbital angle ; first two small, third longer than 

 the sum of first and second, fourth small. Two transverse grooves in front of the 

 posterior margin. Middle lobes of front narrow, rounded, separated from each other by a
