Nares, F.B.S., entitled ‘A Narrative of a Voyage to the Polar Sea during 1875-1876,’
published in 1878. In that short contribution we stated that the collection was so
interesting and the specimens were so variable, that we should publish their descrip-
tion in a separate Monograph.
The Government Grant Committee of the Koyal Society voted a sum of money in
order to assist us in the production of this work.
We beg to thank Dr. Gunther, F.E.S., in whose charge the specimens now are,
Dr. J. Gwyn Jeffreys, F.B.S., the Eev. A. M. Norman, F.L.S., Dr. Carpenter, C.B.,
F E S., and Major Feilden especially for their kind assistance.
