No. 102. ¢ adult. Alexandra, Dec. 9, 1905. Bill dark

This specimen has puzzled me considerably and it is only 
with hesitation, while awaiting further evidence, that I name 
it, after Gould, Sterna gracilis. It appears to be nearly 
adult, but is unusually small, the measurements being: 
culmen 1°3, wing 8°3, tarsus “8 in. The tail is probably 
undeveloped, being very short indeed and only bluntly forked. 
The most striking difference is in the small bill, which, even 
in its present dried state, may be seen to be wholly of a dark 
red colour (as Mr. Stalker also observes on the label), and 
not black or partly black as in the typical bird. Another 
important difference is shown in the primary-feathers ; these 
are certainly not completely margined with white on their 
inner webs and, by the fourth and fifth, the light patch on 
the inner side becomes almost obsolete, being only apparent 
at the base of the feather. 
Should this example prove to be S. gracilis, it is most 
surprising to find it so many miles inland, for, as Mr. Saunders 
points out, this group of Terns is essentially maritime. 
Mr. Stalker notes that this form is reputed to breed on the 
Brunette Creek.
