1892W. B. Scott in Proc. Acad. Nat. Sci. Phil. 412 As early as the Puerco, however, we find that p4 in every known genus is complicated by the addition of a second cusp upon the inner or lingual side of the protocone, which may be called the deuterocone. 1922W. K. Gregory Orig. & Evol. Human Dentition ii. i. 104 A similarly situated, but better developed, basal cingulum in later mammals may be traced from the premolars, where it gives rise to the so-called ‘deuterocone’ or internal spur, backward to the ‘protocone’ of the molars. 1968R. Zangerl tr. Peyer's Compar. Odontology 188 W. B. Scott thus proposed a special terminology for the description of the premolars, in which the cusps are simply numbered as protocone, deuterocone, tritocone, tetracone, and ‘-conid’ respectively.
1892W. B. Scott in Proc. Acad. Nat. Sci. Phil. 415 In the premolars, therefore, when a cusp occurs occupying the position taken by the metaconid in the molars, it cannot be regarded as homologous with that element, but rather with the deuterocone of the upper premolar and may consequently be called the deuteroconid. 1907H. F. Osborn Evol. of Mammalian Molar Teeth viii. 199 There appears a cuspule on the inner side of the crown of the protoconid... (This is the deuteroconid of Scott's terminology.)

1897W. G. Searle Onomasticon Anglo-Saxonicum p. xii, The Anglo-Saxon personal names may be divided into several classes. 1. The first and chief class consists of names that may be termed dithematic names, as they consist of two elements or themes, mostly monosyllabic, a first element or prototheme, and a second element or deuterotheme. 1937H.

1895Cambr. Nat. Hist. V. 141 It is a curious fact that the result of parthenogenesis in some species is the production of only one sex, which in some Insects is female, in others male; the phenomenon in the former case is called by Taschenberg Thelyotoky, in the latter case Arrhenotoky; Deuterotoky being applied to the cases in which two sexes are produced. 1965F.

1959L. H.
