Of particular zoological interest in this connexion is a Ceylonese genus Dyscritina, in which the cercopods are long, many-jointed and filiform during the early stages of growth, and only assume at the last moult the forcipate structure characteristic of the family.
Of the Ceylonese galls, " some are as symmetrical as a composite flower when in bud, others smooth and spherical like a berry; some protected by long spines, others clothed with yellow wool formed of long cellular hairs, others with regularly tufted hairs."
Ceratophora and Lyriocephalus scutatus, the latter remarkable for its chameleon-like appearance, are Ceylonese.
Among primates, a Ceylonese monkey (Macacus pileatus) has been naturalized in Mauritius for centuries, the circumstances of introduction being unknown.
Finally the name Tarantula, in a scientific and systematic sense, was first given by Fabricius to a Ceylonese species of amblypygous Pedipalpi, still sometimes quoted as Phrynus lunatus.
