' NEOLITHIC " MOSS REMAINS FROM FORT WILLIAM 105 



and especially in T. pseudo-tamarisci, Limpr. (which I take to 

 be only a luxuriant, tripinnate form of T. Philiberti), there is a 

 very distinct difference. The stem leaves in T. delicatidum 

 are (constantly, I believe) comparatively small, from a wide and 

 short base (almost as wide as the whole length of the leaf) 

 abruptly contracted to a proportionally short, not very tapering 

 acumen. In the more robust forms at least of T. Philiberti 

 these leaves are very inucli larger, gradually narrowed almost 

 from the base into a very long, tapering acumen, terminated 

 in recent specimens by the characteristic filiform point. This 

 outline is well shown in the Fort William specimens, furnishing 

 a complete contrast to the form of leaf in T. dclicatulum, and 

 leaving no doubt at all as to the identification. 



Brachythecium rutabulum, B. and S. Scanty. 



B. plumosum, B. and S. In considerable quantity and showing 

 some variation. 



Eurhynchium pralongum (L.), Hobk. Several stems. 

 E. striatum, B. and S. A fragment only. 



E. myurum, Dixon. Two forms, one the ordinary, another a larger 

 one, with wide, obtuse and subobtuse leaves, which I should 

 hesitate, however, to refer to var. robustum, B. and S. 



E. inyosuroides, Schp. Frequent. 



E. rusciforme, Milde. Several fragments. 



Hyocomium flagellare, B. and S. In very small quantity. 



Plagiothecimn undulatitm, B. and S. A scrap merely, but quite un- 

 mistakable. 



Hypnurn fluitans, L. One or two small bits. 

 H. uncinatitm, Hedw. A few branches. 



H. falcatum, Brid. One or two fragments. One stem which was 

 almost certainly this had nearly all the leaf-tissue eroded away, 

 doubtless water-worn, and scarcely more than the stout falcate 

 nerves left. 



H. cupressiforme, L. Very little. 



? H. palustre, L. A scrap of a Limnobium was detected by Mr. 

 Nicholson on a slide which I sent to him containing another 

 plant. It is almost certainly H. palustre. 



H. cuspidatum, L. 



Hylocomium loreum, B. and S. Next to Antitrichia the preponderat- 

 ing plant. 



H. brevirostre, B. and S. In quantity. 

 H. squarrosum, B. and S.
