there. Chehebar says that in drainages that have the big crustaceans, the mink eat lots of them; in other drainages they eat mice. Adrian identified some of the mice as Irenomys. Grigera and coauthors has just published "Flora of Puerto Blest." May 7. Bariloche to Buenos Aires with a dozen live Akodon longipilis for Martha Piantanida. She was supposed to meet me at the airport but didn't show. Turns out, I had given her the wrong date of my arrival. Ho hum. May 8. Buenos Aires. Went to the flea market in San Thelmo and found some good old postcards of Llao Llao, Valle Encantado, etc. May 9. Went to the Facultad de Medicina in the morning and talked with Kravetz, He is not going to the mammal meetings in South Carolina, but still wants to invite the Society to Argentina. Also talked with Maria Isabel Belloqc about her owl predation thesis, and with a new student, David ... , who is doing diet studies of the mice in Kravetz's agricultural/border study area. Gustavo Zuleta was there also. In the afternoon went out to the Natuiral History Museum where the mammal department consists of Martha Piantanida and Abel Fornes's widow (technician). They had some akodons that they wanted me to identify, and we pawed through assorted Buneomys (=Auliscomys micropus) and Phyllotis. They, dressed in their white lab coats with overcoats over them, hunted down skulls (not always successfully) while I peered through the gloom of a distant light bulb at the specimens. There was an interesting series of six Phyllotines from Las Cuevas, Catamarca, that were uniformly pale golden, small feet, phyllotis-like interorbital, throat and belly not Graomys, the teeth somewhat strange: maybe Andalgalomy s. Two much larger beasts from thje same place but greyer, not golden. Also found a Phyllotis osilae from Cordoba Province, and maybe some others; they are going to hunt down the skulls. In the preparator's lab were three jars containing two Buneomys (labels say) from Somuncura and maybe Rio Pichilefu, and the other with a big Notiomys. These presumably were from Bonino, Bellati, and Susan Martin and had been sent to Crespo, who is alive but in poor health. The specimens in the University collection that I contributed to in 1964?) and that Martha curated were pretty much destroyed by rats; the remains were sent to the Mar del Plata museum (Scaglia). Bone chill drove me home at 6. May 10. Buenos Aires. Went to La Plata on the bus. Alcover was not there but was warmly welcomed by Dra.... Brandoni ..., who is interested in fossil Octodontidae, another lady whose husband?? works with sharks, by Diego Verzi, the student who is working with Alcover on Aconaemys, by Richard Madden a yankee from Duke who is working on fossil primates from the La Venta fauna, and his Chilean lady assistant. Pascual was not in but was due to attend a PhD presentation on fossil sharks in the afternoon. The wonderful macro-fossils are still on exhibit but poorly lit, dirty glass, haphazard labelling, and chilly ambiente. There seemed to be much more student activity than at the museum in BA.
