Notes.

Six of the seven adults from Misali Island have an additional palatal tooth, recalling var. scissidens Connolly, 1922, described from Dar-es-Salaam. The additional tooth is not present on either of the two adults from Ras Kiuyu. This is a very widespread species and several such forms have been named. Neubert (1998) points out a discrepancy between Paladilhe’s (1872) description and figure of Ennea isseli Paladilhe, 1872 from Yemen, and figures an additional specimen which strongly resembles Gulella gwendolinae . This raises the possibility that Ennea isseli is a senior synonym of Gulella gwendolinae and, if so, also the question of whether it is truly native to Arabia. A direct comparison of types is advised.
