On Arthrostoma felineum, gen. et sp. nov., a Parasite of Cats

Abstract

This small species of Ankylostome worm was found in the small intestine of a golden cat (Felis temmincki) from Sumatra, in association with numerous specimens of Ancylostoma caninum, A. braziliense and Strongyloides sp. It has been experimentally transmitted to the domestic cat.The cuticle shews not only transverse striations but numerous very fine longitudinal striations.Like Ancylostoma, the body shews a distinct longitudinal torsion, and when the dorsal aspect of the cephalic opening is facing upwards, the posterior extremity is displaced laterally. The body is narrowed anteriorly, terminating in a pyriform buccal capsule which, as in Ancybostoma, opens dorsally. The anterior end does not form a hook– like bend as in Necator and forms allied to it.
