Probably, however, in xxxiii the names of regiments have been omitted after the title _tribunus cohortis_, which occurs six times at the end of the list, and some of these might have been old formations.

APPENDIX I During the course of this essay an attempt was made to estimate roughly the total number of auxiliary troops in existence during the first century, but the evidence for this period was too scanty to permit of discussing further the size and composition of the various provincial garrisons.[446] In the second century, however, the evidence of ‘diplomata’ and dated inscriptions becomes relatively copious, and it has seemed possible to draw up something like an ‘army list’, giving the names of the regiments stationed in every province during this period so far as they are known. Such a list cannot, of course, make any pretensions to completeness, but it is hoped that the main conclusions which it suggests will not be found incorrect, and that it may be of service to future workers in the same field. The period to which the list is intended to apply extends from the death of Trajan, in 117, to the accession of Marcus, in 161, during which no hostilities on a large scale took place, so that in view of the general character of the military system we may safely assume that few regiments were transferred from one province to another. In drawing up the list the following principles have been observed. In the first place, all regiments have been included which are assigned to a particular province by a ‘diploma’ or inscription dated within the limits of the period. Secondly, those regiments are included which can be shown to have existed before and after the period, since they must obviously also have been in existence during it, although their allocation to a particular province is of course not so certain. To this category belong those regiments which, while only mentioned in later inscriptions or the _Notitia Dignitatum_, bear evidence in the titles ‘Claudia’, ‘Flavia’, ‘Ulpia’, or ‘Aelia’ that they were created at an earlier date.
