7 6 ' Shufeldt aud I differ'radically on a question of fact, namely whether the upper cervical ap- terium occurs in the swifts. I am certain that that it does, in spite of Nitzsch's antiquated and inaccurate figure of the pterylosis of Cypselus apus, upon which Dr. Shufeldt lays so much stress. As for the differences be- tween Nitzsch's and Lucas' figures of the hummingbird pterylosis, I think Dr. Shufeldt is most decidedly straining at a gnat! I see no essential differences between the two figures. If there is a "piearian bee" in my "thinking- cap" as Dr. Shufeldt suggests, it is unknown to me for I never believed in the "Picarite" at all, but I am sure that as far as the pterylo- sis is concerned hummingbirds are emphati- cally cypseloid, Dr. Shufeldt to the contrary notwithstanding.
