between the palettes of these animals and those found in the young 
specimen of Furcella which prevents one from saying that the animal 
is absolutely the animal of the Furcella. 
The palettes of Furcel/a were slender, cylindrical, with a dilated 
tip like a double-headed hammier, like the young palette of T'eredo 
malleolum of Turton, but of a much larger size; and they had a 
small, slightly-raised tubercle on the middle of the inner side of the 
dilated end. 
The palette in the two specimens of Teredo which we have lately 
received is of precisely the same form, and nearly of the same size ; 
but instead of having this small tubercle, the middle of the dilated 
end is produced into an elongated process about half an inch long, 
which is more slender and oblong at the base, thicker, flattened, and 
dilated above, and truncated at the top. 
The valves of the shell are exactly like those of the Teredo navalis, 
T, norvegicus, and other normal species of the genus, but larger. 
I am inclined to name this species Teredo furcelloides; for I 
do not think it would be safe to decide, without further evidence, 
that it is the animal of Furcella, Lamk.; but at the same time I 
consider it right to bring the occurrence of this animal at once before 
the Society, as it has led me to doubt if my conclusion was correct 
that Furcellais a genus of Conchiferous Mollusks without any valves, 
as I was inclined to believe before the animal occurred, and which 
the evidence then before me led me to believe was a correct conclusion. 
The palettes are situated at the hinder end, just within the edge 
of the mantle, the siphons being quite distinct from or within their 
base. The siphons are slender, of nearly equal diameter, and. united 
nearly to their tips; in their contracted state they just reach to the 
dilated part of the palette at the base of the terminal elongated pro- 
cess. There are some fragments of a thin lamina of shell attached 
to the hinder end of the mantle near the base of the palettes. 
If this should prove to be the animal of Furcella, or even of a 
Furcella-like Teredo, it shows most conclusively that the cup at the 
end of the tubes cannot be regarded as the analogue of the true 
valves of the genus, as I have also proved in a former paper (see 
Proc. Zool. Soc. 1858, p. 258). 
If these animals prove to belong to the genus Furcella, as I su- 
spect they may, then that genus or group of species will only be 
separated from the other Teredines by the habit of living in sand, 
by the club-shaped form of the tube closed at the end with two 
arched plates, the division and separate prolongation of the tubes of 
the siphonal aperture, and the hammer-like form of the palettes.

Near the middle of May a pair of these birds formed a rude nest 
of dry rushes on the ground ; and soon afterwards two eggs were laid. 
The parent birds took turns upon these eggs during the time of in-
