en found only in Borneo and Sumatra, but as Sumatran types
have been found in Tenasserim, perhaps some day the _Ptilocercus
Lowii_ may be discovered there. It has a rather shorter head than
the true Banxrings, more like _T. Ellioti_, but its dentition is
nearly the same, as also are its habits. Its chief peculiarity lies
in its tail, which is long, slender and naked, like that of a rat
for two-thirds of its length, the terminal third being adorned with
a broad fringe of hair on each side, like the wings of an arrow or
the plumes of a feather. There is an excellent coloured picture of
it in the 'Proc. Zool. Society,' vol. of Plates.

I had almost concluded my sketch of the Insectivora without alluding
to one most interesting genus, which ought properly to have come
between the shrews and the hedgehogs, the _Gymnura_, which, though
common in the Malay countries, has only recently been found in
Burmah--a fact of which I was not aware till I saw it included in
a paper on Tenasserim mammals by Mr. W. T. Blanford ('Jour. As. Soc.
Beng.,' 1878, page 150). Before I refer to his notes I may state that
this animal is a sort of link between the _Soricidae_ and the
_Erinaceidae_, and De Blainville proposed for it the generic name
of _Echinosorex_, but the one generally adopted is _Gymnura_, which
was the specific name given to it by its discoverer, Sir Stamford
Raffles, who described it as a _Viverra_ (_V. gymnura_); however,
Horsfield and Vigors and Lesson, the two former in England and the
latter in France, saw that it was not a civet, and, taking the naked
tail as a peculiarity, they called the genus _Gymnura_, and the
specimen _Rafflesii_. There is not much on record regarding the
anatomy of the animal, and in what respects it internally resembles
the hedgehogs. Outwardly it has the general soricine form, though
much larger than the largest shrew. The long tail too is against its
resemblance to the hedgehogs, which rests principally on its spiny
pelage.

The teeth in some degree resemble _Erinaceus_, the molars and
premolars especially, but the number in all is greater, there being
forty-four, or eight more. It would be interesting to know whether
the zygomatic arch is perfect and the tibia and fibula united, as
in the hedgehogs, or wanting and distinct as in the shrews. I have
given a slight sketch in outline of the animal.
