Brief Aug 19, 1932 a total of 103 snakes for less than two weeks at Murcié. On the way out, we stopped at Arroyo Guayaque to seine fish. Arroyo is 20 miles from Murcielago. The seining was remarkably good, catching at least eight species in- cluding one little beast which looks like an athorine. In Alamos we stopped to meet Jim Hilton, who talks much as he writes. He showed us four Terrapene klauberi which he is going to give the San Diego Zoo and gave us some Hemidactylus from alamos. Past Navajon we ran into a very heavy thundershower. The roads were very muddy and difficult to drive. We met an American who said that there was a bad spot further on where two trucks were stuck, and the only way past was in the railroad bed. We decided that this obstacle would better be faced in daylight so we asked out, hoping for a dry morning. is an athorine of a genus previously recorded further north than Mazatlan.
