    Three new species of Eimeria are described from iguanid lizards of Central and South America. The oocysts of each species have no micropyles or residua and the sporocysts lack Stieda bodies, but all have a sporocyst residuum. Eimeria sanctaluciae n.sp. was found in the St. Lucia tree lizard, Anolis luciae, collected from the Maria Islands, Lesser Antilles. The oocysts are spherical to subspherical, averaging 17.3 x 16.5 microns, with a single layered colourless wall; about 60% contain polar granules. The sporocysts are ellipsoidal and average 7.7 x 5.5 microns. Eimeria liolaemi n.sp. was recovered from the blue-gold swift, Liolaemus taenius, from Chile. The oocysts are spherical to subspherical, measuring 21 x 20.1 microns with a single-layered colourless wall. The sporocysts are subspherical and average 7.4 x 6.8 microns. Eimeria caesicia n.sp. is described from the Brazilian collared iguanid, Tropidurus torquatus. The oocysts measure 27.4 x 23.7 microns, are spherical to subspherical, with a bilayered wall, the outer surface of which appears pale blue in colour, the thin, inner wall appearing brown, when viewed by direct light under the optical microscope. The sporocysts are subspherical and average 9.4 x 7.2 microns. Unnamed polysporocystid oocysts with dizoic sporocysts are reported from the faeces of the lesser St. Vincent tree lizard, Anolis trinitatis and the possibility of spurious parasitism briefly discussed. In addition, oocysts of an unnamed Isospora sp. with a smooth oocyst wall which closely resembles I. reui were recovered from A. trinitatis

    El volumen dedicado al Gran Mariscal de Ayacucho (Venezuela, 1795-Colombia, 1830), presenta 225 documentos, de entre los casi siete mil que ha dejado, la gran mayoría escritos de su puño y letra. Ellos nos ofrecen, más allá del perfil establecido por la historiografía tradicional, la viva imagen del gran americano, del brillante militar, del estadista y del magistrado, y destacan, asimismo, dos de sus preocupaciones fundamentales: la unidad latinoamericana y la educación. Siendo una misma la causa de los americanos, es una misma nuestra patria, escribía en 1821. Y para la realización efectiva de esa unidad, Sucre tenía una confianza total en la acción educativa. Esta edición suministra elementos precisos para la cabal comprensión de la extraordinaria personalidad de una de las más auténticas glorias de América
