Decapod Crustacea of Bermuda, Part II. 79 



it; in arm Hiatus it usually barely reaches it. The second anten- 

 nular segment is about equal to the third in both species, but is 

 stouter and more hairy in armlllatus. Seen from a nearly front 

 view, the front edge of the carapace of the latter is 5-lobed or 

 sinuous, due to emarginations above and below the ocular lobes 

 and on either side of the rostrum. In hctcrocluclis this edge is 

 nearly evenly curved. 



In armiUatus the second joint of the antennae has three small 

 distinct denticles on the outer edge, the lowest bearing a minute 

 spine ; in lietcrocli(clis the denticles are scarcely distinct, except 

 the lower, which usually is a very minute spine, scarcely worthy of 

 the name, not visible from above. 



The large chela of armiUatus differs in its longer form and 

 hairyness, and the grooves and furrows of the dactyl and form of 

 the plunger ; there is no supermarginal groove on the inner side 

 of the palm, while in hctcrocluclis it is conspicuous. The carina 

 and lateral grooves of the dactyl of the smaller chela of the male 

 are also characteristic of the latter. No. 1829 I. River. 



Legs of third pair are little compressed, and have about eight or 

 nine pairs of small spines beneath, besides the distal ones, all 

 accompanied by many short hairs and a few long ones, especially 

 distally; ischial spine inconspicuous or lacking. Fifth legs are 

 smaller, nearly terate, and have a brush of many rows of short 

 hairs ending about the middle ; dactyl flatish, curved, acute. 



This species is not common at Bermuda. At least, very few 

 specimens referable to it are in the collections that I have studied 

 from there. In the Yale Museum there are specimens from Fort 

 Macon, N. C. (No. 1830) ; Beaufort, N. C. ; Indian River, Fla. 

 (No. 1760, figured) ; Key West; Sarasota Bay, West Fla. (No. 

 1725 figured) ; Colon; etc. 



It has been recorded from North Carolina to Rio Janiero 

 (Kingsley) ; Bermudas (G. Brown Goode, coll.) ; Mamanguape 

 to Maceio, Brazil; Porto Rico, off Vieques Island, 16 fathoms 

 (Rathbun). The specimens from Panama, in the Yale Museum, 

 referred to this species by Kingsley, prove to be a distinct species. 

 (See our plate xxxiii, figures 1,2.) 



The specimens from Beaufort, N. C., as figured by Brooks and 

 Herrick, seem to be unquestionably of this species. Their beauti- 

 ful colored figure (pi. II) is an excellent illustration of the male 

 of this species when fully developed and highly pigmented.
