Pearson - 1995 8 Davis. Dr. Delia Enria and G. Calderon from Pergamino gave a presentation on Hanta Virus and snowed us with the precautions necessary. I talked with her later, and gave a blood sample. She firmly defended her territory against any incursions by me or Hjelle. Nadia Guthman and Mariana Losada did some work for her (at El Bolson?) and are hoping that Enria can help them get support for a study of the ecology of whatever species of mice are involved. Pergamino has already taken a sample of 49 mice from the El Bolson region, but everything was negative. The banquet was attended by at least 100 people, mostly young, perhaps students taking "Cursos" at the meetings. We were seated at 10:30 p.m., fed at 12, came home at 1:00 when the fun was just starting. Much din. The new president is Reca. Roig and Kravetz were not present. Piantanida appeared briefly for her poster session. There was one session containing 17 oral presentations about Ctenomys. On Saturday morning, after the meetings were over, I went to the Museum and met Pardinás there, who showed me some tuco skulls that he had recovered from owl material in a cave in Rio Negro. Some of them seemed to be too large for haigii or mendocinus. I also looked through a cabinet of mouse secimens, skins and skulls. Many of them are old, even Budin specimens, Not enough material to form a critical mass. However, I do not know what else is available in the Paleontology section of the Museum. I suspect that there are serious territorial problems. Tonni, the mammalogist, did not attend the meetings; it is said that he had recently had an appendectomy. Luciano De Santis and Marcelo Tejedor from the Facultad de Ciencias Naturales y Museo, Catedra de Anatomia Comparada, Paseo del Bosque, and Pablo Straccia from the Escuela de la Salud y del Comportamiento, Catedra de Introduccion a la Ecologia, Mar del Plata gave me a manuscript to read concerning recent records of Lestodelphis. Later, F. J. Goin from the Departamento Cientifico Paleontologia Vertebrados, Museo de La Plata, asked me to be a co-author on a manuscript that was essentially a revision of the genus Lestodelphys including a couple of fossil species. He seemed to
