made, but unfortunately they had to be left behind, and only 
seven species were accidentally preserved which were collected 
in Grinnell Land and at Cape Baird. These'were Cetraria cucul- 
lata, (Bell.) Ach.; C. chrysantha, Tuckerm.; Peltigera aphthosa, 
(L.) Hoffm.; Placodium elegans, (Link) DC.; P. crenulatum, 
(Wahlenb.) Tuckerm.; Cladonia rangiferina, (L.) Hoffm., and 
Omphalaria (?). This last was collected on quartz at the ex- 
_ treme northern point reached, and appears not to have been in a 
state to admit of its being satisfactorily determined. Mr. Lein- 
hart compares it with O. Sz/estaca, Koerb., but which, according 
to that author himself, (Parerg, p. 443), is the same as O. phyl- 
lisca, (Wahlenb.) Tuckerm., Syn., p. 140. 
The writer remarks on the scarcity of C. rangiferina in Grin- 
nell Land as compared with its abundance in Scandinavia. In the 
former it is rare and cannot forma source of food supply for animals.
