In Halcyon rufa (fig. 1), H. sp., Geryle alcyon (fig. 2), and 

 C. americana there is only a single tendon, but it gives off a for- 

 wardly running wriatward slip. The main tendon, as in Alcedo, is 

 continued over the muscles of the forearm to the ulnar side. In 

 Ceryle (fig. 2) there is this difference, that the main tendon is 

 very wide and diffused. Sauropalis sordidus (somewhat unex- 

 pectedly) agrees with Halcyon in its single tendons.

In Dacelo, Sauromarptis, Pelaryopsis, Sauropatis (fig. 3) {sanctus, 

 albicilla, vagans, Moris), Oittura (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 vvristward 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 I)r. E. O. Cunningham, lie pointed out the 

 existence in Ceryle stellata of a tendinous link uniting the two 

 hivcntres 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
