To complement the Fact Sheet on Bornella hermanni, which Angas (1864) described and illustrated from Sydney Harbour, here is a scan of the original watercolour from the collections of the Australian Museum Library. It clearly shows the three pairs of dorsolateral processes, which are one of the characters differentiating this species from B. stellifer. Although the published colour painting (Angas, 1864: Pl VI, fig. 1) does not show the colour pattern clearly, Angas was a skilled and accurate artist and in the original painting the colour pattern of white specks, broken orange lines, white papillae and lack of orange rings on the dorso-lateral papillae, are accurately recorded. Bornella hermanni is not uncommonly found in central and southern New South Wales.
I have also included a photo of a specimen photographed by me from Sydney for comparison.
