130 Notes on North American Crustacea^ 



Great Egg Harbor, N. J., by Professor Baird. I have also 

 dredged it in the harbor of Beaufort, N. C, and off the neigh- 

 boring coast at the depth of from two to seven fathoms. 



Palacmonetes exilipcs, nov. sp. 



Rostrum long and slender, longer than the antennal scales, and 

 with its dorsal crest rising i-ather abruptly (more so in some speci- 

 mens than in others) a short distance behind the eyes, and serrated 

 with six (rarely seven or eight) small, acute, equidistant teeth, sepa- 

 rated rather widely from each other at base ; the second tooth is 

 placed just over the base of the eye-peduncles. The point of the ros- 

 trum is very slender and acute, never bifid ; and the inferior crest is 

 armed with two or three teeth. Antennulse variable in length, but 

 usually half or two-thirds as long as the body, with the outer flagel- 

 lum longest, and having the thick part much shorter than the slender 

 part, and united to it for nearly the whole of its length. Feet very 

 slender and naked ; in the second pair the carpus is a little thickened 

 toward the extremity, and reaches to the end of the antennal scale ; 

 and the hand is small, about half as long as the carpus, and but little 

 thicker than its extremity. Fifth pair of feet longer than the third 

 and fourth, and reaching a little beyond the extremity of the anten- 

 nal scale. 



Length about an inch and a half. 



This species has been distributed under the name Palaemo- 

 noj)sis exilipes. 



Found in fresh water at Somerville, S. C, by Dr. Charles 

 Girard. 



lieaiicfer pandaliformis, nov. sp. 



liostrum slender and much longer than the carapax and than the 

 antennal scales, curving upward, and very slender at the extremity. 

 Its dorsal crest commences at the anterior third of the length of the 

 carapax, and its posterior two-thirds is armed with seven teeth, the 

 second tooth being over the base of the eye-peduncles ; its anterior 

 third is unarmed, except by a minute tooth close to the extremity. 

 Below, the margin of the rostrum is densely fringed with short hairs.
