intermediate between pumilum and “ griseiceps.” The latter 
I consider to be unquestionably the grey extreme of the same 
species, the rufescent phase of which is G. pumilum—the 
differences being exactly parallel with those noticeable in G. 
gnoma.

Ir must not for one moment be thought that these notes pro-

I then crossed the island and spent a short time at Bastia 
and Aleria on the east, returned to Ajaccio on March 19th, and

Though the laws concerning guns hampered me consider-

permitted. Thus was my chance of noticing several more
