Observations on shells in India, listing some specimens with particular regard to their locality, elevation, and relationship to other known types.

Responds to CD’s criticism of his use of word "Kingdom" in discussing geographical distribution of Crustacea.

What does CD think of A. R. Wallace’s paper in the Annals & Magazine of Natural History ["On the law which has regulated the introduction of new species", n.s. 16 (1855): 184–96]? EB considers it good on the whole.

Japanned variety of peacock.

Regional variations in bird species.

EB has little faith in the aboriginal wildness of the Chillingham cattle.

Races of humped cattle of India, China, and Africa.

Indian and Malayan gigantic squirrels, with various races remaining true to their colour, would afford capital data for Wallace, as would the local varieties of certain molluscs. Has Wallace’s lucid collation of facts unsettled CD’s ideas regarding the persistence of species?

Bengal hybrid race of geese is very uniform in colour and as prolific as the European tame goose [see Natural selection, p. 439].

Will see what he can do for CD with regard to domestic pigeons.

Reports success of hybrid cross with Vallota and the failure of another cross.
