First Records for the Ruddy-tailed Flycatcher and Purple-crowned Fairy Hummingbird from Mexico.-On November 4,1961, near the Laguna Cob& 8 miles southeast of Tenosique, Tabasco, I collected two species not heretofore recorded from Mexico. Within a period of fifteen minutes, I obtained a pair of Ruddy-tailed Flycatchers (Terenotriccus erythvurus) and a female Purple-crowned Fairy Hummingbird (Heliothryx barroti) . The Ruddy-tailed Flycatcher has previously been taken in Guatemala and British Honduras, from which areas it ranges southward to Brazil and Bolivia. The race of this species that reaches Tabasco is T. e. fulvigukztis. The Purple-crowned Fairy Hummingbird has also been taken in Guatemala and British Honduras, and it ranges southward as far as Colombia and Ecuador. Laurence C. Binford, my field companion, and I subsequently saw the Ruddytailed Flycatcher on November 6, 7, 11, 13, and 14, 1961, at the same locality, and Binford collected an additional female on November 6. We subsequently saw the fairy hummer on November 5, 6, 12, and 13, 1961, and Binford obtained a male on November 6. The two species were found both within the rain forest and at its edge. These records were obtained while on an expedition sponsored by the Louisiana State University Museum of Zoology, at which institution the specimens are now deposited. -DELWYN G.
