The _Forastero_ class includes all the cocoas which have thick skins and large pods with rather flat beans.] [Footnote 2: _S. singularis_, a nearly allied insect, is common in certain localities and does similar damage.] [Footnote 3: Cf. _Bull. Ent. Res._, vol. i. (1911), p. 83; _Bull. Imp. Inst._, vol. viii. (1910), p. 150; vol. xiv. (1916), p. 174; vol. xviii. (1920), p. 319.] [Footnote 4: This has since been identified with _Gelechia gossypiella_, Sanders, an insect which subsequently effected such enormous damage in Egypt.] [Footnote 5: These names are substituted for Bauchi and Nupe in the old system.] [Footnote 6: Lady Lugard, _A Tropical Dependency_, 1905, p. 236 _et seq_.] [Footnote 7: _Ibid._, p. 209.] [Footnote 8: Included in Southern Nigeria exports.] [Footnote 9: Including copal resin.] [Footnote 10: Including dressed skins.] [Footnote 11: Identical with what is termed _E. biplaga_ at Ibadan, but probably a local form of _E. insulana_.] [Footnote 12: For the most recent information respecting cotton cultivation here and elsewhere in West Africa, Professor Dunstan’s Reports to the Brussels Congress of Tropical Agriculture (1910) should be consulted.] [Footnote 13: Since named _S. guineensis_ var. _robustum_, Stapf.] Transcriber's note: pg 42 Changed: and Protectorate, to: Protectorate. pg 77 Changed: decending the rapids to: descending pg 91 Changed: some localites to: localities pg 146 Changed: ap-apparently rather harsh to: apparently pg 165 Changed: _Apocynacea_ to: _Apocynaceæ_ pg 171 Changed: _Lophila procera_ to: _Lophira_ pg 172 Changed: _Nicotiana tobacum_ to: _tabacum_ pg 174 Changed: _Pseudrocedrela Kotschyi_ to: _Pseudocedrela_ Other spelling inconsistencies have been left unchanged.
