Family IX. EURYL^MID^. 



The Ewylcemidce have heen variously arranged by naturalists, 

 but until recently have been usually referred to the neighbourhood 

 of Coracicts, and considered to be non-Passerine *. Nitzsch, in his 

 celebrated ' Pterylography,' first showed that the pterylosis of 

 Eurylannns is that of the Passeres; and Blanchard subsequently 

 figured the sternum, and proved that this is also of the Passerine 

 form, although the manubrium sterni is unforked, contrary to what 

 is generally the case in the typical Passeres t. 



In 1877 + Garrod further showed that the palate of these birds is 

 truly Passerine, but that they differ singularly from all other known 

 Passeres in the structure of the foot. The tendon of the flexor 



Left foot of Cymborhynehus macrorhynchus viewed from behind, to show the deep 

 plantar tendons, and the vinculum (v.) which the flexor longits hallucis 

 (f.l.h.) sends to the tendon of the flexor profundus digitorum (f.p.d.). 

 The skin has been turned aside, and the superficial flexors removed ; the 

 flexor hallucis longus has been cut short and displaced. 



(P.Z.S. 1880, p. 382.) 



longus hallucis sends out a strong vinculum to join the tendon of 

 the flexor profundus digitorum, as is the case in nearly all non- 

 Passerine birds in which a hallux is developed.
