E. B. Delabarre, Ph. D. 197 



The latest publication on the lichens of Labrador is the pamphlet enti- 

 tled Labrador, published by Dr. F. Arnold at Munich in 1896. This is 

 based on the work of Meyer (i), Schlechtendahl (2), Breutel (3), Tucker- 

 man (4), Wainio (5), and Eckfeldt (6), and on specimens collected by the 

 Rev. Mr. Waghome and communicated to Dr. Arnold by Mr. J. W. Eck- 

 feldt.

The total number of species given in Dr. Arnold's list is one hundred 

 and twenty-seven, besides numerous varieties and forms. The present 

 collection of forty-three specimens includes five species which are not 

 recorded in Dr. Arnold's list, namely, Cetraria Islandica van platyna, 

 Cetraria cuctillata, Theloschistes poly carpus, Lecanora palles- 

 cens, and Cladonia bellidiflora var. ochropallida. 



1. Cetraria arctica, (Hook.) Tuck. On Mt. Fatmee, at an altitude 

 of 3,500-4,000 ft.; also at Nachvak. The species appears in Eckfeldt's 

 enumeration. 



2. Cetraria Islandica, (L. )Ach. Mixed with Cetraria cucuUata 

 and C. nivalis. Both Arnold and Eckfeldt credit it to Labrador upon 

 material collected by the Rev. Mr. Waghome, and in my own herbarium 

 I have material collected by him at Battle Harbor. 



3. Cetraria Islandica, (L.)Ach., d. platyna (Ach.)Th. Fr. With 

 the preceding species and also mixed with Cladonia rangiferina, CI. syl- 

 vatica and Stereocaulon tomentosum. A specimen in my herbarium 

 was collected by the Rev. Mr. Waghome at L'anse au Loup. 



4. Cetraria Islandica, (L.)Ach., b. Delissei (Bor.) Schaer. This 

 variety is recorded in Eckfeldt's list, and a specimen in my own her- 

 barium was collected by the Rev. Mr. Waghome at West S. Modeste. 



5. Cetraria cucuUata, (Bell.) Ach. On Mt. Faunce, 3,500-4,000 ft. 

 altitude, and at Nachvak, with Cetraria arctica, C. Islandica and Cla- 

 donia rangiferina. Evidently this is one of the most common species 

 as indicated by the fragments mixed with many other lichens, though it 

 does not appear in Dr. Arnold's list. 



6. Cetraria nivalis, (L.) Ach. On Mt. Fatmee, 3,500-4,000 ft. alti- 

 tude; other specimens have no definite locality recorded. It occurs alone 

 and mixed with Cetraria Islandica and species of Cladonia. It is given 

 in Eckfeldt's enumeration, and a specimen in my herbarium was col- 

 lected by the Rev. Mr. Waghome at Battle Harbor. 



7. Cetraria Fahlunensis, (L.) Schaer. The species is recorded in 

 Eckfeldt's enumeration, and my herbarium contains a specimen collected 

 by the Rev. Mr. Waghome at Battle Harbor.
