Two interesting and unusual Spiruroid parasites have been reported from the intestines of marine fish. These are referred to the new genera and species, namely, Bulbocephalus inglisi and Cestocephalus serratus. The former is characterized by a globular head and the muscular oesophagus has two bulbs in its most anterior part. The glandular portion of this oesophagus is 20–25 times as long as the muscular part. The diganosis of Cestocephalus serratus is mainly based on the presence of an oblong head which is covered anteriorly by lobe-like structures in the manner of bothridia in some Cestodes. A new subfamily (family Spiruridae) has been proposed to accommodate Bulbocephalus gen.nov. The family or subfamily diagnosis of Cestocephalus gen.nov. has been restricted at present due to the paucity of material.
