Aegires punctilucens - Alder & Hancock's illustrations

July 12, 2005
From: Bill Rudman


To accompany my discussion [message #14248] on Aegires punctilucens and A. exeches here are two of Alder & Hancock's illustrations of a specimen he described from England to compare with the original illustrations of A. punctilucens from D'Orbigny (1837: Fig 106, figs 1, 3) [message #14230].

The figures [Pl 21, figs, 2, 4] show that the flattened tubercles in d'Orbigny were probably exaggerated but Alder & Hancock again show the characteristic coloured spots, with black dots around the edge of the brownish band. Of particular interest is the clearly bifid tip to the rhinophore, which Alder & Hancock mention in the text and which Fahey & Gosliner state is characteristic of the Indo-West Pacific A. exeches but is absent in the Atlantic A. punctilucens.
