THE CRUSTACEA OF NEW JERSEY. 305 



The very curious free-swimming young- were taken in towing 

 nets. Large examples are eight to ten inches long and about 

 two broad. By means of the strong raptorial claws the animal 

 can hold its prey securely, and can give a severe wound to the 

 human hand, if handled incautiously. It also uses the stout 

 caudal appendages, which are armed with spines, very effectively. 

 The colors are quite vivid, considering its mud-dwelling habits. 

 The body is generally pale green or yellowish-green, each seg- 

 ment bordered behind with darker green and edged with bright 

 yellow. The tail is tinged with rose and mottled with yellow and 

 blackish. Outer caudal lamellae with base and spines white, last 

 joint yellow margined with black. Inner ones black, pale at base. 

 Eyes bright emerald-green. Inner antennae dark, with yellow 

 band at base of each joint, and flagellum annulated with black and 

 white. 



I have seen this species several times in New Jersey, as at Cor- 

 son's Inlet, Stone Harbor, Anglesea and Cape May. During 

 191 1 Mr. Brown secured several at the latter locality, and these 

 are the basis of the above description. During that season the 

 species was abundant about Cape May. It has also been found 

 near Point Pleasant. 



During May of 1912 several large examples were seined in 

 Chincoteague Inlet at Wallop's Beach, Virginia, with Crago sep- 

 temspinosus, Callinectes sapidus, Ovalipes ocellahis and Pala:- 

 monetes vulgaris. 



Mr. W. T. Davis tells me has obtained it on two occasions on 

 the south side of Staten Island, N. Y. 



Order SCHIZOPODA. 



TJie Schizopods. 



Mandibular palp generally exceeds length of mandible itself. 

 Maxillipeds sometimes quite pediform. First pair of legs de- 

 veloped as true gnathopoda, and others uniform, not cheliform 

 or modified as prehensile organs. Exopods stronglv developed 

 on all limbs of trunk. Ova invariably placed below trunk and
