THE CRUSTACEA OF NEW JERSEY. 317 



above eye-socket, with nine teeth, of which six on rostrum, and 

 last back about opposite ends of grooves which extend parallel 

 along base of carapace keel anteriorly. Position of this last spine 

 thus about midway in length of carapace. Ophthalmopod mod- 

 erate, depression on which it rests small. Eye large, and peduncle 

 not nearly so robust, though basally becoming more bulky. 

 Antennulues with large peduncle, not quite extended so far an- 

 teriorly as rostrum tip, basal joint trifle more than half length 

 of rostrum, second joint less than half length of first, and third 

 joint half length of second. Edges of antennules and scales 

 setaceous. Flagella of antennules biramous, outer branch a little 

 longer than peduncle and inner branch about half length of 

 outer. Antennae with very short though robust peduncles of 

 three rather uneven subequal joints, and flagella extremely long 

 filaments, about one and four-fifths times length of entire ani- 

 mal. Rostrum rather compressed, unarmed, very slightly inclined 

 upwards towards tip, and two denticles on lower edge. Antennal 

 spine, hepatic spine, carina and groove all well-defined. Hepatic 

 spine with nearly horizontal suture below. Cervical suture ex- 

 tends half way from hepatic spine to dorsal keel. Outer joint 

 of mandibular palp much larger than inner, very wide. First 

 maxilla with long endognath, and well segmented. First maxil- 

 liped with slender four-jointed endopod and lamellar unseg- 

 mented exopod. First and second gnathopods with well-de- 

 veloped epipods, and exopods large. Peraeopods all with small 

 exopods, and only first, second and third with epipods. Pleopods 

 all robust, well developed. Telson with deep median groove, and 

 ends in sharp point. Color mostly transparent, turning brownish 

 in alcohol. Length of body from tip of rostrum 195 mm. 



Remarks. — This southern species occurs occasionally as far 

 north as the shores of our State at least, though it does not seem 

 to have been recorded north of Norfolk, in Virginia, before. 

 It occurs associated with the preceding species, and is doubtless 

 confused by such observers as casually notice large prawns. 

 Southward it ranges to Florida and the Gulf of Mexico. I know 

 of two large New Jersey examples, one secured at Holly Beach 

 in August of 1893 by Mr. N. H. Boon, and another taken at 

 Adantic City in 190 1, and obtained from Mr. C. Buvinger.
