The morphology ofTrypanosoma striatin.sp., from an Indian fresh-water fish

The new species ofTrypanosomadescribed in this paper is parasitic in the blood ofOphicephalus ( = Ophiocephalus) striatusBl., an air-breathing teleostean ‘Serpentfish’ found extensively in the fresh waters of India. This fish is one of the important food-fishes of India, especially in areas far away from the sea, which are mainly served by inland fisheries. It is equipped with an elaborate accessory air-breathing organ and therefore survives when taken out of water and kept in a moist condition. This hardiness of the fish has made it a popular item of diet since it is available in the hottest months of the summer in a fresh condition or even alive. With the expansion of the inland fisheries of India the importance of fishes of the genusOphicephalusis also on the increase.
