life more highly colored than the smaller ones. The carapace and legs 

 were finely and elaborately variegated and mottled with red, yellowish- 

 brown and gray, producing the general effect of reddish-brown. A 

 small, whitish spot, bordered with brown, appeared behind the bases 

 of the posterior lateral spines. The under side was pale orange, pink- 

 ish around the mouth, deeper orange on the chelipeds and legs, and 

 with some spots of orange-brown on the basal segments of the abdo- 

 men. The chelae, above, were deep red-brown, the fingers crossed by 

 two light orange-red bands ; the iridescent area on the outer surface 

 reflected prismatic colors, but especially green, red and silvery tints. ' ' 

 ''Younger specimens, noted by my son, C. S. Verrill, in April, 1898, 

 had the following colors in life : Carapace light gray, with darker 

 shades over the cardiac region and around the edge of the carapace. 

 Ventral surfaces white. Chelipeds light gray, purple at the joints. 

 Ambulatory legs light gray, except the posterior legs, which have a 

 red blotch on the last joint. Eyestalks light gray, the eyes black. 

 Chelae with a brilliant iridescent area." (Extract from Decapod 

 Crustacea of Bermuda.) 



Material examined: One male, Bury Island, Bahamas, January 

 21, 1923; one male from Turtle Harbor, Florida, November, 1924, 

 taken by the " Ara," William K. Vanderbilt, commanding. 



Technical description: Carapace oval, 27.5 mm. long, 40.5 mm. 

 wide from tip to tip of lateral spine; frontal margin from tip to tip 

 of preorbital spines 10.5 mm. wide ; the preorbital teeth are triangular, 

 acute, separated from the four frontal teeth by a very deep V-shaped 

 sulcus ; the four frontal teeth are prominent, subequal, subacute, tri- 

 angulate, separated from each other by V-shaped sinuses of approxi- 

 mately the same size as the teeth. The inner, inferior orbital angle is 

 dorsally prominent, triangular; there are two closed sinuses on the 

 superior orbital margin; one V-shaped sinus on the outer half of the 

 inferior orbital margin. There are nine teeth, including the postorbital 

 tooth on the anterolateral margin ; of these the second to fifth inclusive 

 are subequal and slightly larger than the sixth to eighth teeth, which 

 are narrower basally and also subequal ; each of the anterolateral teeth 

 has the tip acute, forward-directed, the posterior lateral margin con- 

 vex, the anterior margin, concave. The ninth or lateral spine is acute, 

 directed outward and slightly forward and in the males is twice or 

 more than twice as long as the eighth spine. The postlateral margin 

 is shorter than the anterolateral and concave ; the posterior margin is
