Campylorhynchus jocosus
Oct. 21 El Batel, 5100 feet, Sinaloa.
One group found in dense brush just north of the pass, apparently a family group. Three were collected on October 17. Two more were seen at the same place today. The call-note is a harsh rattle, unlike that of any when I have ever observed in that the quality of tone suggests that of Sciuus.
The species has not been seen elsewhere, and [illegible] has been collected or seen by Leopold or Russell.
