Geographical variation: — The following may be regarded as 
sub-species:—(1) 4. g. glareolus (Schreber) of West-Central Europe, 
from the Baltic to the Alps and Pyrenees and from the Atlantic coast 
to Silesia, is brighter in colour, and perhaps on the average 
(hind foot, 16-6 to 18; condylo-basal length of skull, 23 to 24-6 mm.) 
slightly larger than (2) E. g. britannicus. (3) E. g. suecicus (Miller) of 
the Swedish and Finnish lowlands with the Somes sae watershed of 
Norway, has the red mantle narrower and the sides and face greyer 
than in &. g. glareolus. (4) E. g. ¢stericus (Miller) of the Danube basin, 
from Bavaria through Piaseaty to Rumania, and probably to Bulgaria 
and the Black Sea coast, has also a narrow mantle, but is lighter and 
yellower, and has the auditory bullae more abruptly inflated on the 
inner side. (5) 4. g. helveticus (Miller) of the Jura Mountains, the non- 
Alpine parts of Switzerland, and the lower western French Alps, is a 
pale buffy-grey form with the hind foot 17 to 19 and the condylo-basal 
length of skull 23 to 25-4 mm. (6) &. g. sazanzcus (Thomas) of the 
Syansk Mountains, Lake Baikal, is a small grey form with short brain- 
case, hind foot 16, and condylo-basal length of skull 23 mm

* Adams's results agree closely with those of other observers, as Hollis (MS.) in Devon, and with the 
average for all Britain, as shown by specimens in the British Museum; they may fairly be taken as repre- 
sentative for the sub-species britamnicus. All the specimens were dissected.
