1896.] THE SECRETARY ON ADDITIONS 10 THE MENAGERID, 303 
The last three or four tracheal rings are closely united, but not 
fused, to form a box, and there is a well-marked pessulus. The 
first bronchial semiring, to which the intrinsic muscles are attached, 
is much longer from back to front, and is arched in the usual way. 
After this follows a rather deep semiring, which is immediately 
succeeded by several thinner bars ; these latter get deeper towards 
the opening into the lungs. 
§ General Observations and Classification of the Laride. 
In having no ambiens Rhynchops is unique among the Laride, 
but not among the Limicole in general, if, that is to say, we 
include, as I think should be done, the Auks in the Limicole. In 
the latter group the ambiens is sometimes present and sometimes 
absent. The Gull-tribe can be conveniently (even if merely arti- 
ficially) divided up as follows, Rhynchops undoubtedly belonging 
to a distinct subfamily, not definitely nearer to the Terns than to 
the Gulls :-— 
Sternine. ABXY-+*. Cxca nipples. Biceps slip present. Ex- 
pansor secundariorum absent. 
Rhynchopine. ABXY—. Ceca nipples. Biceps slip and ex- 
pansor secundariorum absent. 
Larine. AXY+. Czxca nipples, biceps slip, and expansor 
secundariorum present. 
Stercorariine. AXY+. Czxca long. Biceps slip present. Ex- 
pansor secundariorum absent. 
I should regard Gygis as a Gull and Anous as a Tern, on 
account of their leg-muscles; but then Anouws has the eapansor 
secundariorum. These two genera require further investigation 
before they can be placed; and I am a little suspicious that they 
may be found to destroy the neatness of the above arrangement.
