from Anglesea, the only known instance, I believe, of the occurrence 

 of this species in the Coastal District. 



The Submaritime group characterizes the narrow zone which 

 marks the transition from salt marsh to sandy upland. The soil of 

 this zone is a silt darkened by organic matter. Normally it is quite 

 damp, but, except in the more depressed areas where the ground is 

 soggy, it forms a firm sod due to the interlacing rootlets of the thick 

 vegetation which covers it. The Submaritime zone evidently marks 

 the line along which the seepage of fresh water takes place from the 

 mainland. Chemical analysis of the water from the same zone at 

 Cold Spring Harbor, Long Island, showed it to be entirely fresh, ^* 

 though salt water occasionally invades the zone at the highest tides 

 or during severe storms. The dominant vegetation consists of a 

 mixed growth of Spartina patens and Juncus gerardi on the firmer 

 areas and of a nearly pure groAvth of Scirpus mnericanus in the wet 

 depressions. Other plants more or less frequent in this zone are 

 Echinochloa walteri, DistichUs spicata, Scirpus olneyi and 7'obustus, 

 Dondia maritima, Tissa marina, Kosteletzkya virginica, Ptilimnium 

 capillaceum, Sabatia siellaris, Asclepias lanceolata, Gerardia purpurea 

 and maritima, Pluchea camphorata, Iva oraria and Baccharis halimi- 

 j'olia. 



The Orthopteran faunule of the Submaritime zone is especially 

 distinguished by the abundance of Clinocephalus elegans, which 

 frequents the Spartina patens- J uncus gerardi areas, and of Orcheli- 

 mum herhaceum, which is partial to the patches of Scirpus americanus. 

 The entire faunule includes the following species: 



Tryxalis hrevicornis Conocephalus nebrascensis 

 Pseudopomala brachyptera " caudellianus 



Meryniria vigilans " palustris 



Clinocephalus elegans " fuscostriatus (?) 



Chloealtis conspersa Orchelimum herbaceum 

 M elanoplus feniur-nibrum " spimdosum 



Paroxya floridiana Xiphidium fasciaium 

 Conocephalus lyristes " spartince 



" exiliscanorus 



Of these species the most abundant in the Submaritime zone is* 

 M elanoplus femur-rubrum. Next to it in point of numbers comes 

 Xiphidium fasciatum. Other abundant species are Clinocephalus 

 elegans, Paroxya floridiana and Orchelimum herbaceum. Locally 

 Tryxalis brevicornis is common in the Scirpus areas. The remaining
