31 May 87 Campi Lowell. 6148 461 Tiris fumidus Laying 6149 462 Myiarchus sp? 9.9X14.1 ♂ 6150 463 Ditto 9.6X13.7 ♀ 6151 467 Ditto 9.5X12.5 ♀ Laying. I. Mr Brown, Bill I big black, A little before sunset I heard a Call note resembling that of M. cinerascens but differing very that I thought it worth while in- vestigating, with the result of seeing four of the above species, and obtaining three of them. They were in low Magnit trees, and easily approached. Did not notice any prentiariitis as it was late and I shot on sight. Stomachs contained portions of buttle. They appear to differ from M. erinitis, especially in greater length.
