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 woodcut, 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. 3. 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 Linnsean 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. BIBLIOGRAPHICAL NOTICE.
