Cotugnia columbae sp.nov. from the domestic pigeon is described and compared with other species of the genus. The tapeworm measures 108–130 mm in length and 2·236 mm in maximum breadth. The rostellum bears 200 hooks, 7·7–10·6 μm. long arranged in two rows. Testes number 105–130 and the cirrus pouch measures 0·354–0·376 x 0·054–0·065 mm.We are grateful to Dr C. M. Singh, Director, Indian Veterinary Research Institute, and to Dr H. D. Srivastava, erstwhile Assistant Director and Head of the Division of Parasitology, for their interest in these studies and for the provision of the necesssary facilities.

The post-cercarial development of G. crumenifer (Creplin) has been experimentally elucidated.Gyraulus convexiusculus (Hutton) serves as the intermediate host under natural conditions.The adult stage of the fluke was raised experimentally in ruminants, the time taken by the parasite to attain maturity being 118 days in the kid and 114 in the buffalo calf.Cercaria chungathi Peter & Srivastava, 1955, has been established to be the larva of Gastrothylax crumenifer. The cercaria, the redial parthenita and the metacercaria have been described.The authors are grateful to the Director, Indian Veterinary Research Institute, for his keen interest in these studies.

In 586 .iortrial laciabons of 150 Friesian cattle maintained at the National Veterinary' Research institute, Vom, from 1968 to 1983. Maximum milk production ,was attained in the fifth week of lactation. The fourth and sixth lactation curves showed superiority over the first, second, third and fifth. The curves apparently indicate that culling of unproductive animals before the 6th lactation could be economically unreasonable.
