Based on published records of earlier collections, a list of marine algae was compiled totaling 178 species: Chlorophyta-15 genera, 29 species, Phaeophyta-19 genera, 34 species, Rhodophyta-76 genera, 112 species, Cyanophyta-2 genera, 3 species. The history of marine algal collections in Libya is discussed briefly. Oceanographic Expedition (1908-1910 were identified and published by Lemoine (1915) and Petersen (1918). Muschler (1910) and Pampanini (1931) compiled lists of marine algae from Tripolitania and Cyrenaica. Fragmentary algal collections dredged by a DanishPresently, extensive collections are being made along the coast in preparation for the publication of a complete marine algal flora of Libya. It was thought necessary to have a correct nomenclatural and taxonomic list of the species thus far reported by previous workers. It

Cross-national variation in elder health is well established, with older adults in developing countries reporting poorer health than elders in developed countries. However, cross-national research using performance-based assessment is rare. We examined grip strength in American and Indian elders using a common methodology and found that older adults in India had significantly poorer strength than the US sample even when matched for age, gender, medical conditions, and self-rated disability. The difference in performance is likely explained by life-long differences in nutrition, occupational demands, and access to medical care. These differences in health among people who have survived to old age may also explain differences in life expectancy in later life.
