and 1 were doubtful as to the tletermiiijition oi' one of the t'ornis; a spoci- 

 iiien was sent to Mr. Macvicar, wlio named it as " one of the numerous 

 forms of Lophozia aJpestris^ a very eommon plant in Spitzbergen." 



L. EXCiSA var. cylindracea (Dum.) K. M. A plant from Bear 

 Is. and Prince Charles Foreland may belong here, but it more 

 probably belongs to an innovating form of anotlier species. 



L. BIOUKNATA (Scluuid.) Dum. Klaas Billen Bay. No perianths 

 were present, but the odour was cliaracteristic. 



HARi'ANTiius SCUTATUS (W. ct M.) Sprucc, was present in small 

 (piantity in material from l>ear Is., Hermansen Is., and l^-ince 

 Charles Foreland. The specimens, as Mr. Jones remarked, were 

 very variable in regard to infolding of leaves, frequency and size 

 of underlcaves, and amount of thickening at cell-angles, much more 

 so than is usual in Britisii plants. 



Ckpiialczia Bici siMDATA (L.) Dum. Bear Is. and Prince Charles 

 Foreland. 



C. LEUCAXTiiA Spruce. AVith Blepliarostoma trichoplnjUum on 

 Bear Is. 



C. RECLUSA (Tayl.) Dum. = C. serrifora Lindb. A small quantity 

 of what appeared to be this species was mixed with G. hicuspidata 

 and JVebera nutans from Bear Is. As it was sterile, much broken 

 up, and on an unusual habitat, the determination is doubtful. 



Cepiialoziella 15YSSACEA (Both.) Warnst. Damp slopes, 

 Prince Charles Foreland. The plants were sterile, and the formalin 

 had injured them so much that it is impossible to give a definite 

 determination. The leaves were distant, two-thirds bilobed into 

 acute segments ; the apical leaves were eroded by the formation 

 of two-lobed gemmse ; small 2-3-celled, subulate underleaves w^re 

 present at the apices of the shoots. A packet from Vogel Hook con- 

 tains a sterile plant which is best referred to the above species, though 

 the lobes are not so divaricate as usual. Cephaloziellas were present 

 in other samples, but were so much injured by the formalin that deter- 

 minations would have been little more than mere guesses. 



Blepiiahostoma trichophyllum (L.) Dum. Often abundant 

 and in almost pure masses. Bear Is., Cape Boheman, Hermansen 

 Is., Advent Bay, Gips Valley, and Klaas Eillen Bay. 



Anthelia juratzkana (Limpr.) Trevis. In wet region (drain- 

 age channel), Bear Is. This had suffered so much from the formalin 

 that it was difficult to recognise as an AntJielia, but INIr. Knight 

 reassured me on that point. 



Ptilidium cn.iAPE (L.) Hampe. Abundant and often in pure 

 masses ; dry tundra and among boulders, Bear Is. ; damp slo})es. 

 Prince Charles Foreland and Advent Bay. In bogs, Advent Bay, 

 the form inundatum Schiffn. was collected. 



P. PULCiiEiiRiMUM (Web.) Hampe. Damp slopes, Prince Charles 

 Foreland. 



ScAPANiA CURTA (Mart.) Dum. Eock-crevices, Bear Is. and 

 Cape Boheman. From the latter locality the var. geniculata 

 (Massal.) K. M. was also collected. 



S. lERTGUA (Nees) Dum. Bear Is. 



No holoarctic species was found in the collection, though careful
