Nematodes of the superfamily Rhabditoidea are usually free-living; however, a few species appear to be definitely parasitic. The Nematode described in this paper belongs to the latter group. It was found in large numbers in the small intestine of one of two bats, Lasiurus borealis, captured September 15th, 1932, in the vicinity of Washington, D.C. Additional specimens of this species of bat were not obtained for examination. Two specimens of each of two other species of bats, Eptesicus fuscus and Nycticeius humeralis, collected from the same locality were negative for this parasite. The Nematode is a member of the family Cylindrogasteridae Chitwood 1933, and appears to be congeneric with Longibucca vivipara Chitwood 1933, found in the wall of the stomach of a South American snake, Pseudoboa cloelia.

“Piranabú,” “Piranampú” or “Piranampú” (the last according to Goeldi, 1898) are local names on the Amazon applied to the siluroid fish which, so far as it is possible to determine from memory and from the rough sketches and notes which I made at the time, is the modern Pirinampus pirinampus (Spix). This fish, of which I examined eight examples, attains a length of at least 60 cm., has an elongated adipose fin more than one-third the length of the entire body, microscopic scales, possesses maxillary barbels about half the length of the body, and in general appearance closely resembles the figure (Tab. VIII, a) of “Pimelodus ctenodus” provided by Spix (1829). I am much indebted to Mr J. R. Norman, of the British Museum, for his kind assistance in identification.

Turning sickness of cattle, a very fatal disease, long known in tropical East Africa, is characterised by circling or turning movements made by the affected animals. Recent observations prove that the malady occurs sporadically throughout Uganda and in the greater part of Kenya and Tanganyika where East Coast Fever is highly enzootic. It appears to occur mostly in hot dry periods of the year.
