forms ; fourteen species {LoxophyUum lamella^ Elir. ; Loxo- 



jphyllum fasciola^ Ehr. ; Ampliileptus anaticula, Ehr. ; Cydt- 



dhim glaucoma^ Ehr. ; Pleuronema chrysalis, Elhr. ; Condylo-

Ehr. ; Aspidisca turrita, Ehr. ; Eiqjlotes cJiaron, Ehr. ; Sfylo- 



nychia piistulata, Ehr. ; Metopus sigmoides, Chip. & Lachm. ; 



Vagi'mcola crystallino, Ehr.; Cothurnia imberhis^YAxx.) occur 



both in fresh Avaters and in the sea; two genera [Chanostoma 



margaritiferam and Sjjarofn'cha vexillifer), tliree species 



[Holophrya gido, Chlamydodon cyclops, and Ervilia saltna), 



and four varieties [Cothurma tmherhis, A^ar. curvula, Vagini- 



cola crystallina, var. annulata, Vurticella microstoma, var. 



h'dophila, and Vorticella nehidifern, var. saUna) are new; 



and the Infusoria wliich have hitherto been known only out 



of fresh waters are represented only by six species {Enchelys 



nebulosa, Ehr.; Cyrtostomum leucas, Stein ; Cinetochilummar- 



qaritaceum , Ehr. ; Glaucoma scintillans, Ehr. ; Halteria gran- 



dincUa, Ehr. ; and Stichotricha Miil/eri, Lachm.). 



Of Rhizopoda the following were fuund in the salt-pool of 

 Szamosfalva : — Eleiirojd/rysJielix^Yntz] Flecfophrys proli'fera, 

 Entz ; Euglyplia piisilla, Entz ; Microcometes tristripetus, 

 Entz ; Orbulinella smaragdea, Entz; Ciliophry!^ infusionum, 

 Cienk. ; Amoeba guttida, Duj. ; Amoeba Umax, Duj. ; Amoeba 

 •princeps, Ehr. ; Amadxi dijffiuens, Ehr.; Amoeba radiosa, Ehr. ; 

 and JPodosfoma Jiligerum, Clap. & Lachm.* The general 

 character of the Khizopod-fauna of the salt-pool may be 

 summed up as follows : — '^ On the whole, the salt-pool is 

 poor in Rhizopcid-forms ; those forms occur in greatest number 

 which, while they are very common in fresh water, are pro- 

 bably to be reckoned in the series of those organisms which 

 occur both in fresh and in sea water ; among the compara- 

 tively numerous forms peculiar to the salt-pool the specific 

 allies of two {Euglyplia pusilla and Microcometes tristripetus) 

 have hitherto been found only in fresh water, while the nearest 

 relative of another species [Plcia-op/irys Helix) lives in sea 

 water; of two new genera {Flecfophrys and Orbulinella) one 

 {Orbiilinella) is allied to the marine Foraminifera with per- 

 forated shells ; and, finally, it may be noted as a negative 

 character, that the Arcellce, so numerous in fresh waters, and 

 which are so easy to find that one can see them with the 

 naked eye, as well as the Diffiugice, which are equally abun-
