32. Notes on the Species, External Characters oe Habits of the 
Dugong.— By N. Annanvate, D.Sc., Deputy Superintendent 
of the Indian Museum. [ With three plates. i 
The present communication is largely of the nature of a pre- 
liminary notice. Later I hope to offer to the Society a memoir on 
the anatomy of certain organs an a in the Dugong, 
he I eum. 
At present : feel confident in sagan Serg four fully adult Indian, 
two fully adult Australi : and part three immature Indian 
skulls before me) tha e individual. poate among Indian 
specimens are at ‘ante as Mein as those which were believed by 
Owen to constitute a specific difference between Indian and 
these cannot be specific, hey are not constant even in a series 
wen’s Halicore australis, therefore, must 
be relegated, as most recent ce ene have thought pro- 
bable, to the synonomy of H. dugon 
n the summer of 1905, I was Stel by the authorities of 
the Taian Museum to visit the northern part of the Gulf of 
Manaar, in order to obtain a complete skeleton and skin of an 
collection, and the most nearly perfect skeleton, having 
obtained from Queensland in exchange with the Brisbane 
Museum. Thanks largely to the ae offices of the Rev. A. D. 
Limbrick, of Raémandd, I w: fortunate as to obtain a fine 
male, the external characters of hich w are described below :—

better not to change it
