Chiefly an enumeration, with descriptions of new species, of the 
Orchids collected by Barter and Mann. Of the 67 species 
examined 48 were previously undescribed. But little resemblance 
is traced with Abyssinian species; only one species of JEulophia 
being common to W. Africa and Abyssinia.

Malmgren, J.—Ofversigt af Spetsbergens Eanerogam-Elora. Tv. 
Vet.-Ak. Eorh. 1862, p. 229. Ninety-three phanerogamic Spits¬ 
bergen species are enumerated, of which fifteen are new to Dr. 
Hooker’s list (Linn. Trans, xxiii. p. 283, where the Spitzbergen 
species are indicated by S. in the column 4 Arctic Europe’). On 
the other hand Dr. H. has eight or nine not in Hr. Malmgren’s 
enumeration. Spitzbergen is said to be richer in species, con¬ 
sidering its latitude, than any other Arctic tract. This is attri¬ 
butable, to the influence of the Gulf-stream. Of the 93 species 
81 are common to Greenland. It is remarkable, however, that 
none of the species common to these Eloras are absent from the 
Arctic Elora of the mainland of the Old World. Hr. Malmgren 
says the Elora of the Northern Coast of Spitzbergen, under 80° 
lat. differs considerably from that of the Western, and approaches 
in character to that of Lancaster Sound, Barrow’s Straits and
