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

but after the severe storm of September 4, 1913, another individual was found in a small boat that had 

 been sunk off Pivers Islands. On August 20, 1914, 6 specimens, 3 males and 3 females, were collected 

 under the rocks of the jetty east of Fort Macon. A male and female were found together in every case 

 in a hollow under a flat rock. The males were colored much like C. heterochcBlis , except that the con- 

 spicuous orange and vermilion areas on the tail fin were lacking. The females were a deep greenish 

 blue with white marking on the large chela. During the night of August 20 a large male shed his 

 shell but increased very little, if any, in length. _ To provide for the withdrawal of the large hand through 

 the relatively very slender wrist a large oval area on the upper and inner surface of the proximal part 

 of the shell of the hand is detached and the carpus, meros, and ischium, at least, are split lengthwise 

 so that the hand is not drawn through them at all.

Cephalothorax about half as long as abdomen, subcylindrical, with a large sinus in front behind the 

 eyestalks in which the rostrum appears as a small median projection. Eyestalks contiguous, broad at 

 the base, corneal surface well developed 

 and, in lateral view, with.a minute point on 

 the anterior surface. Antennular and an- 

 tennal peduncles very long, the former with 

 a short scale which barely exceeds the 

 basal article, and the latter with a long nar- 

 row scale which extends to the middle of 

 the terminal article. Third maxillipeds 

 exceeding antennal peduncles by less than 

 the length of their terminal article. Cheli- 

 peds unequal and somewhat dissimilar, the 

 larger one appearing to be stouter and 

 rougher than its mate; fingers slightly gap- 

 ing, the thumb in line with the hand and 

 broad at base ; movable finger much narrow- 

 er and rather strongly curved ; carpus short ; 

 meros about as long as movable finger. Sec- 

 ond pair of legs about as long as chelipeds 

 but very slender, weakly chelate and with 

 the carpus divided into five articles having the proportions of I , i^/.Vs 



Abdomen well developed, compressed, with strong swimmerets.

a. Front of carapace and appendages, lateral view; h, the same, 

 dorsal view; c, large hand; rf, second leg; e, telson and uropods. 



Telson tapering, armed above 

 at each side with two spines, one of which is at about the middle of the length and the other at about 

 halfway between the middle and the distal end; terminal spines well developed. Urftpods with oval 

 blades. 



Length of a female (type) i6 mm. ; cephalothorax 4 mm. 



Color, in life almost transparent except for a small amount of red pigment on the appendages and 

 telson. 



A single specimen, a female carrying orange-yellow eggs, was collected on Shark Shoal breakwater 

 July 9, 1916, by Mr. O. W. Hyman. It was kept alive in the laboratory for over a month, during which 

 time the eggs dropped off without hatching and the animal moulted twice without appreciably increasing 

 in size. 



The species appears to be very close to A. evermanni Rathbun but differs in the length of the third 

 maxillipeds, the proportions of the articles of the carpus of the second pair of legs, the arrangement 

 of the spines of the dorsolateral stu^ace of the telson, the width of the caudal laminae and the slightly 

 more developed rostrum. It also bears a good deal of resemblance to A. acanlhopus De Man, but it 

 differs from it in having the scale of the second antenna longer than the basal article , the more extensive 

 corneal siuface of the eyes and the outline of the front margin of the carapace. From both these species
