Anatomy. — “Concerning an Isolated Muscle of the Ciliary Body 
of the Pigeon’s Eye, Situated near the Eye-splt’. By J. H. 
ZALMANN. (Communicated by Prof. J. BOEKE). 
(Communicated at the meeting of June 25, 1921). 
When making a sagittal section of the pigeon’s eye we soon reach, 
after the cornea and the iris, the eyesplit situated in the basis of 
the iris and in the basement membrane of the corpus ciliare. 
In the ciliary body peripheral to this eyesplit we are then parti- 
cularly struck with a stout muscular fascicle which, in virtue 
of its firm structure, projects into the spaces of Fontana and is 
distinguished from the other ciliary muscles by its peculiar form.
