524 BIRDS OF SOMERSETSHIRE. 
Family CoLyMBID#. 
The Colymbide or Divers may be divided into 
two families, the Grebes and what may be called the 
true Divers. The Grebes are separated not only 
from their near relations, the Divers, but from all 
the rest of the birds in this great Order, by the 
formation of their feet, which are not fully webbed, 
like the others, but much more resemble the lobe 
foot of the Bald Coot, the membrane, however, in 
this case reaching the whole length of the toes, 
without being indented at the joints as in that bird: 
in other respects they very much resemble the rest 
of the Divers. Of the Grebes I can include three 
out of the five British species, and of the true Divers 
two out of the three, making five Somersetshire 
species out of the eight British Colymbide. 
GREAT CRESTED GREBE, Podiceps cristatus. The 
present species, the Great Crested Grebe, can only 
be considered a rare accidental visitor to our county. 
‘There are two specimens in the Museum at Taunton, 
one presented by the Rev. Gerald Carew at the same 
time as the Osprey, before mentioned (ante, p. 4), 
and probably also shot in the ponds at Chargot; 
and another, a young bird of the year, in the collec- 
tion formerly belonging to the late Mr. Beadon, and 
said, in his note-book, to have been killed in West 
Sedgemoor when it was much flooded. Mr. Sanford
