guished by its larger size throughout, and by the greater amount of white mirror in the pattern of 
the three outer primaries.” My experience of the species does not exactly accord with this; for in 
all the specimens I have examined the size has not exceeded that of L. sco;puUnus, whilst the bill 
has been slightly narrower. As will he seen from my descriptive notes above, the markings on the 
primaries are somewhat variable, and therefore too inconstant, taken alone, to serve as a specific cha- 
racter. It appears to me that the pale brown colour of the bill and feet, which in the other species 
are arterial red all the year through, affords the safest criterion for distinguishing this bird. 
All the examples of this Gull I have hitherto met with have been collected on the Otago coast, 
in the southern portion of the colony. 
Mr. Saunders has courteously placed at my disposal the woodcuts by means of which he demon- 
strated the differences in the primaries of the three allied species.
