 joint of second to fourth pairs of feet with pointed process. First

 peared. Length 2.7 to 4.5 mm. 



Male. — 'Body more sharply defined behind than in female, so 

 that at dorsal end a slightly gibbous projection. Cephalosome

 prominent. Lateral corners of last pedigerous segment less pro-

 thoracic segment. Anterior antennae straight, with first and sec- 

 ond joints fused. Mouth-parts as in female. Urosome rather 

 narrow, second segment largest. Outer rami of last pair of legs

Remarks. — On June 21st, 191 1, this species was taken in 

 great abundance in surface towings in Great Egg Harbor Bay off 

 Ocean City, by Mr. W. B. Davis and the writer. We found 

 quantities of the megalops of various common crabs, together 

 with the fry of Menidia menidia notata and Syngnathns fusciis, 

 and various medusse, associated. It was also very abundant in 

 Great Bay, in Ocean County, on July ist to 3d, 191 2, when we 

 secured myriads in surface towings. Inland, as far as the salt 

 water extended, we found them in countless numbers, even in 

 the quiet little estuaries. In such places many were eagerly de- 

 voured by the abundant young silversides (Menidia menidia 

 notata). The above description and the accompanying figures 

 were made from examples obtained in Great Bay. Mr. F. J. 

 Keeley has also obtained it in abundance in surface towings off 

 Longport. 



The coloration of this species is given h\^ most writers as often 

 more or less tinged with lig-ht red, and the antennae are often
