. Bulletin of the British Ornithologists' Club. Vol. 87 48 Bulletin annually plumaged Abyssinian populations of cinereola. The great sexual dimorphism in size in chiniana is evident in the figures for heterophrys and also for ukamba when Lynes' figures, based on many more specimens, are used. Again, restricta and distincta agree in showing the least dimorphism. Summarizing what can be learned from museum specimens restricta appears most nearly related to distincta. However, the marked difference in habitat, arid sandy thorn bush versus rocky, grassy hillsides, is too great to unite them

The final disposition of restricta must await its study in the field. 40 E. restricta Map of East Africa showing the distribution of the new species Cisticola restricta , and its possible relatives chiniana, distincta and cinereola.
