A previously undescribed virus has been isolated from Culex spp., Psorophora ferox and sabethine mosquitoes in Trinidad. The name Aruac is proposed for this agent. Aruac virus has not been isolated from any source other than mosquitoes. Neutralizing antibody to the virus has not been demonstrated in human serum. Some of the physical and biological properties of the virus are described. (AU)

179 blood specimens from inhabitants of Grenada were collected in August, 1956, and have been studied for evidence of immunity to a number of insect transmitted viruses. Haemagglutination-inhibition tests and virus neutralization tests have been employed in these studies. There is evidence that dengue infection has been prevalent, principally in coastal towns and villages. The presence of Ilheus and St. Louis virus remains conjectural. Yellow fever, from our data, might have been present last in Grenada at the turn of the century. (AU)
