Show 348 THE SECRETARY ON ADDITIONS TO THE MENAGERIE. [May 4, &c. 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 shownf that in the Passeres and in Upupa epops the tendons of the flexor 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, II, III, IV, representing 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. Fig. 1. Left foot of Gallus bankiva; V, vinculum running downwards from the outer hallucial tendon to the inner digital common tendon. 2. Right foot of Apteryx mantelli. 3.
