Eirenis coronella shows geographical variation in ventral scale count, the number increasing from the west to the southeast (Table 2). This probably clinal variation has been partly responsible for the recognition of the subspecies E. c. fraseri. Apart form its higher ventral scale counts, this taxon is said to be more robust than typical E. c. coronella from further west and to have a more obscure pattern. However these features show considerable variation through the range of E. coronella and the status of its presently recognized subspecies needs reappraisal. Eirenis arabicus is said to differ from E. coronella in its narrower head, more tapering frontal scale which is longer than the snout and by the presence of six instead of seven upper labial scales on each side. As stated, body proportions in Eirenis are often quite variable, especially when preservation artifacts are included, and the head of the type of E. arabicus is not in fact exceptionally narrow. Frontal shape is also rather variable in E. coronella and, contrary to Haas, here too this scale is usually longer than the snout. The reduction of upper labial count from seven to six occurs occasionally in E. coronella by loss of the suture between the six and seventh labial scales; in some cases this fusion may be incomplete (see Fig.5). It seems therefore that E. arabicus is conspecific with E. coronella. The Eirenis coronella from southwest Saudi Arabia differ substantially from those found to the north and east and are named below as a distinct subspecies [ARNOLD 1982].
