348 THE SECRETARY ON ADDITIONS TO THE MENAGERIE. [ May 4, 
&e. Dr, Alix* has described how that, in the common Swan 
(Cygnus olor), there is no long flexor tendon to the small hallux. I 
have not examined that species ; but there is undoubtedly a small one 
in C. nigricollis, C. atratus, and in all the other Anserine birds I have 
examined, as above mentioned. However I have found this tendon 
to the hallux wanting in 
Parra africana, Pygosceles papua, 
Chauna derbiana, Podiceps minor. 
Professor C. Sundevall has shown+ that in the Passeres and in 
Upupa epops the tendons of the flezor longus hallucis and the flexor 
perforans digitorum are quite free from one another, not being united 
by any vinculum. In all the Passeres which I have examined my 
observations agree with these generalizations. However, the same 
condition maintains in Botaurus stellaris and almost in Ardea cinerea, 
where the vinculum is scarcely more than a single fibre (vide fig. 9). 
DESCRIPTION OF FIGURES. 
In all the figures the numbering refers to the digits I, I, II, IV, repre- 
senting the hallux, second, third, and fourth digits respectively. In all, the 
deep plantar tendons are alone represented, and these from their plantar aspect, 
the hallucial tendon being the outer of the two at the heel-joint.
