Show 1896.] IN THE ANATOMY OF THE KINGFISHERS. 605 In Halcyon rufa (fig. 1), H. sp., Ceryle alcyon (fig. 2), and C. americana there is only a single tendon, but it gives off a for-wardly running wristward slip. The main tendon, as in Alcedo, is continued over the muscles of the forearm to the ulnar side. Ln Ceryle (fig. 2) there is this difference, that the main tendon is very wide and diffused. Sauropatis sordidus (somewhat unexpectedly) agrees with Halcyon in its single tendons. Fig. 1. Fig. 2. Fig. 3. Pig 1.-Halcyon rufa. Tendons of tensor patagii brevis. Fig. 2.-Ceryle alcyon. Tendons of tensor patagii brevis. Fig. 3.-Sauropatis albicilla. Tendons of tensor patagii brevis. In Bacelo, Sauromarptis, Pelargopsis, Sauropatis (fig. 3) (sanctus, albicilla, vagans, chloris), Cittura (sanghirensis, cyanotis), and Tanysiptera the tendons are more complicated. There are two separate tensor patagii brevis tendons which often converge, and very nearly if not quite meet at their insertion onto the forearm ; the anterior of these, which is alone continued onto the ulnar side of the arm, has a wristward slip. Syma agrees with these genera in having two parallel tendons, but differs from them in having no wristward slip. To another myological peculiarity of some Kingfishers attention was first called by Dr. R. O. Cunningham. H e pointed out the existence in Ceryle stellata of a tendinous link uniting the two Uventres cervicis muscles, and the absence of this link in Alcedo. I have examined the genera mentioned in the table at the end of this paper (p. 606), with the exception of Syma and Tanysiptera (upon which I have a note by Prof. Garrod), and find that there are quite as many genera which have this tendinous link as there |
