250 MR. C. L. MARTIN ON ECHINOPS, 
the light of a canine ; but this tooth differs so little from the acknowledged false molar 
succeeding it, that its claim to the title of canine only rests in its situation. The dental 
formula then of Ericulus stands thus :

The general form of the body, the character of the spiny covering, and the feet, are 
as in Hrinaceus ; the ears are naked ; the muzzle as in Centetes. 
I am the more particular in making these observations, inasmuch as the genus Eri- 
culus, Is. Geoff., closely approximates in its characters to that for which I have proposed 
the name of Hchinops ; but from which, nevertheless, it is sufficiently distinct. 
In the Zoological Proceedings for 1833, p. 81, reference is made to a letter of Mr. 
Telfair’s, accompanying a very young insectivorous animal, known to the natives of 
the interior of Madagascar by the name ‘‘ Sokinah,” and which Mr. Telfair was dis- 
posed to refer to the genus Centetes. 
The specimen in question (preserved in the Museum Zool. Soc. Lond.) was compared 
with young specimens of the common hedgehog (Hrinaceus Europeus, Linn.), and the 
half-spiny tenrec (Centetes semispinosus, Ill.), but being only seventeen days old, its 
characters could not be satisfactorily determined ; the form, however, of the muzzle and 
of the body, together with the array of short close spines, with which it was invested 
above, like a young hedgehog, raised some doubt, at least in my own mind, as to its 
belonging to the genus Centetes. While engaged in examining a collection of speci- 
mens from Madagascar and Mauritius, presented some time since to the museum of the 
Zoological Society by the same gentleman (the late William Telfair, Esq.), from whom 
the ‘‘ Sokinah” had been received, I discovered a specimen of an insectivorous animal, 
the general form and aspect of which strongly led me to regard it as the adult of the 
same species. An investigation of its dentition confirmed the views I had entertained 
respecting the ‘‘ Sokinah,”’ and I at once recognised it as the type of a new genus.
