282 ON THE ANATOMY OF THREE KINGFISHERS. [ May 12, 
I may add a few remarks on some other points in the anatomy of 
the three birds. The tongue of Ceryle stellata and that of Alcedo 
ispida bear a close general resemblance to each other and differ widely 
in form from that of Dacelo gigas. In the first two (figs. 1 & 2) it 
is broad, thin, flat, and sharply acuminate at the tip, while in Dacelo 
(fig. 3) it is much thicker proportionally and of a sagittate form.

3. Tongue of Dacelo gigas. 
he bronchial tubes in Alcedo ispida are considerably longer propor- 
tionally than those of Dace/o gigas. In the latter bird a well-marked 
subtriangular pale yellowish-red gland exists at the external side of 
the origin of each bronchus ; and traces of a similar structure exist in 
the former. The length of the cesophagus in Dacelo gigas is 54 
inches, and that of the intestinal canal 27 inches. There are no 
ceca. The diameter of the first portion of the intestine, which was 
distended with food, greatly exceeded that of the succeeding por- 
tions in the specimen examined. The dimensions of the digestive 
tube in dlcedo I could not accurately ascertain, as the viscera were 
considerably injured ; but Macgillivray, who has figured the digestive 
organs of this species not very satisfactorily (the form of the tongue 
being incorrectly given, and the stomach represented as much more 
muscular than it is in reality), states the length of the cesophagus as 
3 inches, and that of the intestine as 103 inches. The liver was 
larger in proportion and more elongated in form in the specimen of 
Alcedo than in that of Dacelo. The specimen of Dacelo examined 
was a female which had died in the beginning of February ; and the 
left ovary was of a narrow oblong form, its length being 3} lines, 
and its breadth 13 line. The oil-glands of Dacelo and Alcedo 
differ considerably : in the latter the gland is deeply divided into two 
lobes, while in the former the anterior margin is only slightly exca-
