[2] Clarke was also an artist and a collection of his scientific illustrations is held at Museum of New Zealand Te Papa Tongarewa.

[9] Clarke obtained the specimen of Himantolophus appelii, which he described in his scientific paper, from Mr Appel of Hokitika and named the species in his honour.

The address expressed their appreciation of Clarke's work and in particular their recognition of his "study and original observations of the fish of this coast".

A special value attached to these drawings inasmuch as some represented rare and others absolutely unique specimens which had come under Mr. Clarke's observation".

[15] The Museum of New Zealand Te Papa Tongarewa did in fact purchase Clarke's drawings and watercolours from his wife in 1921.
