lower hind angle. Second gnathopods of female with oblong 

 propodus rounded below, and second joint rather broad, also 

 somewhat strongly and evenly convex in front. Lower hind 

 angles of second and third abdominal segments produced into 

 acute triangular points. Rami of first uropods shorter than 

 peduncle. Rami of second uropods subequel to peduncle. Rami 

 of third uropods equal or exceed peduncle, rather large. Telson 

 notched behind, lobes rounded, spinulous. Color olive-brown to 

 olive-green, sometimes reddish-brown. Antennse reddish-brown. 

 Length i8 mm. 



Remarks. — The distribution is from Cape Cod to Texas. I 

 have New Jersey examples from. Point Pleasant and the Manas- 

 quan River banks, secured by Mr. Wilmer Stone. It differs 

 from Orchcsfia agilis chiefly in its larger size, longer first an- 

 tennae, less robust hand of the second pair of gnathopods of the 

 male, of which palm not lobed. and differently shaped second 

 joint in female gnathopods. It also has a different habitat, 

 living usually around the salt marshes, frequently not near the 

 shore. In such localities it is found among grass and weeds, 

 or under various objects affording refuge for concealment. It 

 also runs or crawls more than Orchcsfia agilis, and hops less 

 frequently. It is said to live nearly or quite up to the fresh- 

 water, sometimes occurring in almost dry places above high- 

 water marks.
