DECAPOD CRUSTACEANS OF THE BEAUFORT, N. C, REGION. 391 



to a narrow point. First pair of legs short and stout; hand inflated, with short fingers and articulated at 

 lower angle with carpus; carpus with its anterior margin excavate to receive the hand, its superior angle 

 with a bundle of hairs. Second pair of legs slender, the carpus divided into three articles of which the 

 central is the longest. Third, foiulh, and fifth legs slender, with long spines on inferior margin of 

 propodi; dactyls bifurcate at tip. 



Telson narrow, tapering, upper siuiace with two pairs of small spines near margin, tip obtuse and 

 armed with a strong median spine on either side of which are two slender spines. 



Length of a male, 12 mm.; carapace, including rostrum, 5 mm.; rostrum, 2.5 mm. 



In life it is almost transparent and colorless. It lives among floating Sargassum and at times is 

 easily taken in the harbor and along the sea beaches. An occasional individual is found to carry an 

 isopod parasite {Probopyrus latreuticola Gissler)') in one of its branchial chambers.

Elongate, compressed. Carapace smooth and polished, its anterolateral angle with a spine, a 

 triangular tooth below eye, and a strong spine on either side at base of rostrum. Rostrum slender, almost 

 twice as long as remainder of carapace, rotmded and almost unarmed above, base somewhat flattended 

 and horizontal, distally inclined slightly upward, serrated below and lamellate toward base. Outer 

 flagellum of antennule thick and much shorter than inner, neither quite reaching tip of antennal scale. 

 Antennae longer than rostrum; scale lanceolate, less than half as long as rostrum. Legs all short; first 

 pair very short, stout, hand inflated, fingers curved, closing completely; second pair also chelate, very 

 slender. Carpus triarticulate ; other legs with simple, curved dactyli. 



Abdomen strongly geniculated between third and fourth segments, the third segment of the male 

 bearing a low hump; fifth segment with a spine on each side on posterior margin ; sixth segment with a 

 posterolateral spine and a stronger one on each side at base of telson; telson with two pairs of dorsal 

 spinules, posterior margin armed on each side with one long and one short spinule. 



Length of a male, 40 mm.; carapace, including rostrum, 19 mm.; rostrum, 12 mm. 



Color usually green but sometimes gray or grayish red. 



Very common in nearly all parts of the harbor where there is a growth of Zostera. 



Genus CONCORDIA Kingsley.

Carapace, rather short, elevated and armed dorsally with five or six slender spines the first of which 

 is near the extremity of the rostrum while the last is a little forward of the middle of the carapace, these 

 teeth well separated and the carapace between them not carinate; rostrum short, little if any advanced 

 beyond the eyes. Abdomen strongly bent in the middle; telson narrow, sides straight, tapering to an 

 acute tip. Eyestalks short and stout. Antennules with the basal articles ciliate above, flagella short, 

 the outer one stout and ciliate, the inner one slender. Antennal scale extending to about the middle of 

 the flagella of the antennule; flagellum of antenna slender and about twice as long as the carapace. 

 First pereiopods short, stout, fingers shorter than the palm; second pereiopods longer and slenderer, 

 carpus composed of three articles of which the distal and proximal ones are of nearly equal length and 

 considerably shorter than the intermediate one. The other pereiopods are slender, the propodal articles 

 with a few minute spines on the posterior border, the dactyls short, curved and with spines on the 

 concave margin. 



Length, 8 to 12 mm. 



This species has not been detected within recent years. The original specimen, collected at Fort 

 Macon, by Prof. H. E. Webster and described by Kingsley, is preserved in the United States National 

 Museum. Other specimens are from "off South Carolina, " and Punta Rassa, Fla. The type specimen 

 lacks some of the pereiopods, but the others show that the carpus consists of three articles instead of two, 

 as has been understood from Kingsley 's description.
