PRELIMINARY DESCRIPTIONS OF FIVE NEW SPECIES 



OF CRUSTACEANS FROM THE COAST 



OF NORTH CAROLINA. 



BY W. P. HAY. 



Published by permission of the U. S. Fish Commissioner. 



For some time past the writer has been engaged in the prepa- 

 ration of a report on the decapod crustaceans of Beaufort, N. C, 

 and the surrounding territory, and in the course of the work 

 several new species of these animals have come to light. As 

 publication of the complete report will be considerably delayed, 

 it seems desirable to publish the following brief descriptions of 

 the most important of the new forms. The types have been 

 deposited in the U. S. National Museum and full descriptions 

 and figures will be included in the report. 



Coralliocaris wilsoni sp. nov. 



Holotype, d\ Cat. No. 47,957 U. S. N. M., U. S. Bur. Fisheries S. S. 

 Fish Hawk, about 20 miles off Beaufort, N. C, in 10 to 20 fathoms, 

 August 1, 1914. Paratypes, 2 $s, Cat. No. 47,961 U. S. N. M. 



Rostrum about one-third as long as carapace, slightly decurved and 

 armed above with 11 to 13 acute, nearly equidistant teeth. Antennal 

 scale broad, equal to the rostrum in length. First pair of legs alike, 

 slender, chelate, the tips of the fingers hairy. Second pair of legs very 

 unequal, the larger one, in the male, having the chela so enlarged that 

 its bulk is almost equal to the rest of the animal; hand cylindrical, mov- 

 able finger strongly curved and bent inwards, its cutting edge with a 

 prominent lobe near the base; thumb bent downward out of line with 

 the hand, its cutting edge with two teeth. Smaller chela about one-third 

 the size of its mate, somewhat compressed but otherwise similarly con - 

 structed. 



Three specimens were collected in 1914 from the canals of a large sponge 

 dredged up by the steamer Fish Hawk and a series of 8 or 10 was obtained
