Knight Jones, E. W. (1940). The occurrence of a marine leech, Abranchus blennii n.sp., resembling A. sexoculatus (Malm), in North Wales. Journal of the Marine Biological Association of the United Kingdom. 24(2): 533-541.
Summary. Several specimens of an ichthyobdellid leech were found on Blennius pholis collected on the coast of Anglesey.The leech resembles Abranchus sexoculatus (Malm), a rare form only recorded previously from Sweden and not yet adequately described. Slight differences, however, indicate that it may be a distinct species and the name Abranchus blennii is provisionally put forward for it. A short review of the genus Abranchus and a description of the appearance and structure of the leech follow.
