This appendix is mainly designed to supplement the table on p. 60, by giving a list of the auxiliary regiments grouped according to the provinces in which they were raised. I have also added for the sake of completeness a further section dealing with the _cohortes civium Romanorum_, and a few regiments of which we do not know the place of origin. The list thus contains, or is intended to contain, the names of all the auxiliary regiments known to us, and includes far more than existed at any one time. The greater part of this list is, of course, merely a repetition of that drawn up by Cichorius in his articles on _ala_ and _cohors_ contributed to Pauly-Wissowa, and in view of the admirable summary of the evidence there given I have restricted myself to appending to the title of each regiment the name of the province in which it was stationed, or, when this is unknown, a reference to a single inscription mentioning it. Only in cases where I have been able to add to the list a regiment unknown when Cichorius wrote have I added a note on the evidence. The whole may, in fact, be described as a summary of Cichorius’s articles, with a supplement bringing them up to date, and as such may, I hope, be of some value to students of this subject. As in the list on p. 60, regiments raised before 70 and those of later date are divided into two groups, distinguished by the letters A and B. BRITAIN. _Alae._ A. I Flavia Augusta Germania Superior—Pannonia Britannica M. C. R.[507] Inferior. Brittonum V. Mauretania Caesariensis. _Cohorts._ A. I Britannica M. C. R.[508] Pannonia—Dacia. I Brittonum M. E. Pannonia—Dacia. II Brittonum M. C. R. P. F. Dacia. II Brittonum Mauretania Caesariensis. III Britannorum Raetia. III Brittonum Dacia. III Brittonum V. E. xi. 393. IV and V Brittonum supposed because of the existence of VI Brittonum ii. 2424. B. I Flavia Brittonum Dalmatia—Noricum. I Ulpia Brittonum M. Dacia. I Aelia Brittonum M. Noricum. I Augusta Nervia Pacensis Dacia. Brittonum M.[509] I Aurelia Brittonum M. Dacia. II Flavia Brittonum Moesia Inferior. II Augusta Nervia Pacensis Pannonia Inferior. Brittonum M. BELGICA. _Alae._ A.
