I Ingenuorum C. R.[552] v. 3936. IV Voluntariorum C. R. Pannonia Superior. VI Ingenuorum C. R. Germania Inferior. VIII Voluntariorum C. R. Dalmatia. XIII Voluntariorum C. R. iii. 6321. XV Voluntariorum C. R. Germania Inferior. XVIII Voluntariorum C. R. Pannonia Superior. XIX Voluntariorum C. R. vii. 383. XXIII Voluntariorum C. R. Pannonia Superior. XXIV Voluntariorum C. R. Germania Superior. XXVI Voluntariorum C. R.[553] Germania Superior. XXX Voluntariorum C. R. Germania Superior. XXXII Voluntariorum C. R. Germania Superior. The following regiments seem to have a similar character, although we know nothing concerning the occasion of their creation: I Italica Voluntariorum C. R. xiv. 171. II Italica Voluntariorum C. R. M. Cappadocia. I Campanorum Voluntariorum Dalmatia—Pannonia Inferior. C. R.[554] Lastly, a series of at least seven regiments bearing the inexplicable title of Campestris, of which only the following have left traces: III Campestris Dacia. VII Campestris Syria. The following three regiments should perhaps be included in the same category: Ala I C. R. Pannonia Inferior. Cohors Apuleia C. R. Cappadocia. Cohors I Lepidiana C. R. Moesia Inferior. In a final section I have grouped together regiments which bear non-ethnical titles, and a few cases of ethnical titles which are at present inexplicable, owing to our ignorance of the situation of the tribes referred to. In the former case it must, however, be remembered that many of these regiments may have had ethnical titles which are not mentioned in the only references to them which we possess. _Alae._
