140 ON THE ANATOMY OF THE EURYL^EMID^E. 



instead of being composed of more or less transversely-directed fibres 

 running between the two tendons, as in many birds where this structure 

 obtains. In Euryloemus ochromelas it is apparently double, there being 

 a second additional slip given off lower down from the hallux-tendon, 

 which joins the tendon of the digital flexor at the point where the latter, 

 splitting up into three, receives the main vinculum.

Left foot of Cymbirhynchus macrorkynckus, viewed from behind, to show the deep 

 plantar tendons, and the vinculum (y.), which the flexor longus hallucis (/. I. k.) 

 sends to the tendon of the flexor profundus digitorum. The skin has been turned 

 aside, and the superficial flexors removed ; the flexor longiis hallucis has been cut 

 short above and displaced. 



P. Z. S. 1880, As regards the alimentary canal of these birds, there is nothing

slightly bifid at the tip. Both it and the palate generally are smooth ; 

 along its posterior sides it is provided, as is frequently the case, with 

 about eighteen small, backwardly directed, spiny processes, that at the 

 angle being much larger than the others. There is no crop developed ; 

 and the proventriculus is zonary : in Cymbirhynclius it is |, in E. ochromelas 

 | inch in vertical depth. The stomach has the character of a not very 

 muscular gizzard, and is lined with hardened brown epithelium ; the left 

 lobe of the liver is the smallest (considerably). The caeca are present, 

 as might have been predicted from the nude oil-gland*, and are truly 

 Passerine in nature, being mere nipples J, or, in the smaller species, y 1 ^ 

 inch long. The following are the intestinal measurements :
