No. 10 garth: brachyuran fauna of the galapagos 369 



Color in life. — Carapace clear pearly gray with numerous orange red 

 dots along midline and continued on rostrum. Eye dark purplish red with 

 green highlights; a few red dots on eyestalk. Merus of ambulatory legs 

 banded with similar dots. Chela with faint tint of orange along upper 

 surface. (Petersen) 



Habitat. — Sand, sand and shell, sand and mud. 



Depth.— 20-160 fms. 



Remarks. — This species is the only representative of its genus thus 

 far found on the Pacific side of the Isthmus of Panama. Its similarity to 

 J. frontalis (A. Milne Edwards) (1879) of the Atlantic has been noted 

 in the original description. Because of its wide bathymetric range, 20-160 

 fms, A. hoodensis belongs at once to both littoral and abyssal faunas.
