Color, olive brown to olive green, occasionally reddish-brown ; 

 antennae, reddish-brown. 



Length of female 18 mm., of male 22 mm. 



This species is readily distinguished from the preceding by 

 its larger size, longer first antennae, and more slender second 

 antennae, and by the larger size of first coxal plates. 



Distribution : Cape Cod to New Jersey ; coast of Texas ; New 

 Haven, Connecticut. 



The habitat of this species is different from the preceding, 

 being usually in the neighborhood of salt marshes and often quite 

 far from the shore in almost dry places among grass and weeds. 

 This species crawls more readily than agilis but is a weaker 

 hopper. 



For a fuller account of its habits the reader is referred to 

 Miss Smallwood's contribution in the Cold Spring Harbor Mono- 

 graphs, No. 3, 1905. 



Talorchestia Dana. 



Similar to Orchestia except that first gnathopods in female 

 are simple instead of subchelate and second pereiopods usually 

 have inner margin of dactyl more sharply constricted than in 

 allied genera.-

Eyes large and circular. 



First antennae short, extending slightly beyond penultimate 

 joint of second pair which is one-third as long as body in female, 

 but%which may equal the length of the body in the male; flagel- 

 lum multiarticulate and longer than peduncle. 



Mouth parts forming a conspicuous projection on ventral side 

 of head, extending below the level of the coxal plates. Mandibles 

 without palp. Maxillipeds with triarticulate palp. 



Coxal plates increasing in height and length from the first to 

 the fourth, but not so high as their respective segments, their ven- 

 tral margins slightly rounded and provided with numerous short
