 three, or less than half, can be claimed by us. We

differences, our object at present being merely to 

 act as interpreters of our author, and to place his 

 figures before our readers, in the hope that they may 

 be a farther help to such of them as may desire to 

 become better acquainted with Eoraminifera. 



ANOMODON ATTENUATUS. 



AMONG the mosses are a number of 'species 

 whose head-quarters appear to be North 

 America, where they are common and bear fruit 

 freely; and some of these are found not unfrequently 

 in Europe, but have not been detected in Britain. 

 That several of them ought to occur here is certain, 

 and every year adds a few to our list. 



To my valued correspondent, the Rev. J. Fergus- 

 son, I am indebted for a very interesting species of 

 this kind, which he discovered in August, 186S, 

 growing very sparingly on rotten trunks of trees 

 and damp sandstone rocks, in the Den of Aiiiie, 

 Eorfarshire. 



Anomodon attenuates (Huebener, 1833) ; Hypnum 

 attenuatim (Schreber, 1771) ; Leskea attemtata 

 (Hedwig, 1787). — Dioicous, matted, procumbent, 

 much branched; branches vague, curved at apex, and 

 also taking the form of very slender, attenuated 

 flagellse, deep green. Cauline leaves imbricated, 

 becoming reflexed and patulous when moist, some- 

 times secund ; from a narrow clasping base, ovate, 

 lanceolate, acute, thick, and opaque ; nerve strong, 



pale, vanishing below apex; cells very minute, 

 rounded, finely papillose, paler at base. Perichrctial 

 leaves narrowly acuminate, with the nerve obsolete, 

 and laxer pellucid areolation. Capsule on a largish 

 smooth stalk, erect, cylindric ; lid pale, conic, with 

 an oblique beak. Peristome with long narrow 

 whitish teeth.
