56 Bibliographical Notice. 
yellow, this species can be easily distinguished from the fore- 
going one. 
Dr. Cantor refers to a different species, found in 1836 by 
Mr. Griffiths under stones in the Naga Hills, and to another 
observed in Bengal (vide Ann. and Mag. Nat. Hist.-1842, vol. ix. 
p: 277). 
The eee p. 55, is from a coloured drawing by Dr. Cantor 
in the Collection of the British Museum. The original specimen 
is also in the same collection. 
8. D. Cantoria, n. sp. 
This species, named after Dr. Cantor, who appears to have 
been the first to draw attention to this curious form, is the 
largest of the three species at present known. It was discovered 
by Mr. Fortune, the well-known Chinese traveller. 
In length it is more than double that of either D. Grayia or 
D. ferudpoorensis ; and the expanded hammer-head-like portion 
is exceedingly well marked. 
There is something highly characteristic in the manner in 
which the peculiar longitudinal band (which seems to be of a 
different structure from the rest of the body) terminates towards 
the hammer-headed extremity: in D. ferud- 
poorensis it ends without expanding laterally ; in 
D. Grayia it expands as shown in the previous 
figure ; while in D. Cantoria it terminates in 
the manner here represented. 
There appears to be no trace of this genus in the fine collec- 
tion of annulose animals at the Jardin des Plantes, Paris. 
Full details, with carefully drawn-up specific descriptions, will 
shortly be forwarded to the Linnzean Society ; in the mean time 
this brief notice may cause some attention to be paid to these 
little animals, which doubtless are common on the continent 
of Asia; and the author would be happy to receive specimens, 
so that he may be enabled to complete his account of the 
group. He is led to believe that, in addition to the localities 
given above, they occur likewise in the neighbourhood of Kandy 
(Ceylon) and near Calcutta.
