In the summer of 1907 the Norwegian bryologist, Herr B. 

 Kaalaas, kindly permitted me to accompany him on a collecting 

 trip on the western Norwegian coast in Romsdals Amt. His 

 main purpose was to establish more definitely the northern limit 

 of the Norwegian range of the "Atlantic species," many of which 

 he had himself been the first to find in that country. While I 

 was with him we found one new station for S. planifolia, by the 

 lake Gusdalsvand in Vanelven, a point which we reached from 

 temporary headquarters at Aaeim. Our most northerly oper- 

 ations, and the last before I was obliged to leave, began with a 

 trip by water from Molde to the small fishing village on the low 

 cape Bud. From there we walked to the little settlement of 

 Farstad, as I remember, where we succeeded in finding quarters. 

 It was Herr Kaalaas' idea to investigate from here particularly 

 the high promontory of Stemshesten. We learned, however, of 

 an area of limestone to the southward in the Tverfjeldene* and 

 decided to divide our forces for the one day we had available, 

 Herr Kaalaas investigating Stemshesten, while I tried to reach 

 the marble of the Tverfjeldene. With the time consumed in 

 going and coming, together with a certain amount of climbing, 

 I was not able to make a thorough survey of the place, but did 

 find a number of interesting bryophytes. Among them was a 

 Scapania which I took from its general appearance to be S. 

 planifolia, and it was so recorded b}' Kaalaas as the most north- 

 erly station for this species. t Miillert also records this as the 

 northern limit of the species. On more careful examination my 

 specimen proves, however, to be S. nimbosa. The descriptions 

 of Macvicar§ with figures show two quite distinct species, and 

 I have also been able to compare authentic material of both dis- 

 tributed by the English hepaticologist, W. H. Pearson, so that 

 there is no question as to the identity of the plant. The record 



* The gneiss of western Norway is varied by occasional outcrops of limestone 

 (marble), which are in some cases large enough to support a distinctive calcicolous 

 flora. We had previously driven from Molde to such a locality north of there con- 

 taining a cave (Troldkirken), from which the Tverfjeldene are not far distant.
