The Rev. F.C. R. Jourpatn exhibited a series of over 
80 eggs of the Raven (Corvus corax) from different parts of 
the Palearctic region, arranged geographically to show the 
gradation in size and the greater frequency of the blue type 
of colouring in southern forms. The following races were 
shown :— 
C. corax principalis (Greenland). 
C. c. islandicus (Iceland). 
C. c. corax (British Isles, etc.). 
C. c. hispanus (Spain). 
C. ¢. sardus (Corsica). 
C. c. lawrencet (Cyprus, Mesopotamia, Palestine,and India). 
C. ¢. tengitanus (Algeria). 
C. ¢. umbrinus (Egypt and Palestine). 
The series exhibited represented exactly half the series in 
Mr. Jourdain’s collection. 
Of Corvus cornix a series of 16 clutches was also shown, 
including representative sets of :—- 
C. cornix corn (British Isles, Denmark, Hungary). 
C. c. sardonius (Corsica). 
C. c. pallescens (Cyprus). 
C. ¢. valachus (Romania). 
Among the series of four clutches of the Cyprus form was 
a set of seven eggs, blue, with a few brownish markings. 
The eggs ,of this race are nearly always below the average 
size. 
Mr. H. Mont exhibited an egg of the Satin Bower-bird 
(Ptilonorhynchus violaceus) and an egg of Phonygammus 
keraudrent ; both laid in captivity.
