doubtfully recorded as occurring in Scotland), and hyperborata. 
Comparing the whole known Lepidopterous fauna of Norway 
(east and west of the Fjeld) with that of Scotland, but confining the 
comparison to the Macrolepidoptera, the Scottish Microlepidoptera 
not being yet sufficiently worked out, we get the results shown in

On the Evolution of the Peridinina and the Peculiarities of Organi- 
zation which approximate them to the Noctiluce. By M. 
PovcuHET. 
The author brings forward some observations which, he thinks, 
reveal a new order of phenomena in the genesis of the Peridinians, 
His observations were made in the Bay of Concarneau, when the 
towing-net collected daily the following species :—Ceratiwm furca, 
Ehr. ; C. tripos, Nitzsch; C. tripos, var. megaceros; Dinophysis acuta, 
Ehr. ; ? Protoperidiwm pellucidum, Bergh; Peridinium divergens, 
Ehr.; ? Diplopsalis lenticula, Bergh; ? Glenodinium cinctum, Ehr. ;

The different varieties of Ceratium furca and tripos always oc-
