tion of the types of endings I follow v. Lenhossék in the main, but 
without including, as he does, the fine, net-like terminations of the fibers 
of the radix longa in the category of oculomotor endings. 
The most striking and peculiar as well as most abundant type is 
the calyx ending (Fig. 3, 4, 5, 6). The comparatively coarse oculo- 
motor neurite expands on reaching the ciliary ganglion cell into a cup- 
shaped termination or calyx, with a variable number of sepal-like 
processes. The calyx embraces that pole of the cell from which the 
neurite arises. The ending is intracapsular, as shown by Figure 6, and 
is so closely applied to the cell as to suggest the fingers of the hand 
grasping a round object of convenient size. The finger-like or sepal-like 
processes differ in length. They are usually confined to one half of the 
cell, but one or more may extend as far as the opposite pole. Usually 
they end freely, but they may approach and unite to form one or more 
loops. Occasionally they break up into a small number of terminal 
knobs. The circle of processes extends all the way around the ganglion 
cell, as may readily be determined in methylene blue sections by focus- 
sing through the faintly stained and fairly transparent cell-body. In the 
drawings only the upper surfaces of the cell-bodies have been represented. 
The methylene blue staining, while not as satisfactory for the nerve 
cells (at least in my preparations), brings out the details of these calyx 
endings better than the silver method employed by v. Lenhossék. 
This author describes the terminations as ,gabelformige Endigungen”, 
each being composed of a triangular basal expansion from which two, 
or more rarely three, unbranched processes run meridionally over the 
surface of the cell, but without reaching the opposite pole. Methylene 
blue staining demonstrates the calyx-like form of the ending, and shows 
that the processes are often as many as six, and even more, in number. 
v. Lenhossék recognized the resemblance to the ,Endkelche” of Held 
in the nucleus trapezoides of mammals. Since he found the _ ,gabelfor- 
mig” ending more abundant in a 21-day chick than in adult fowls, 
he looks upon it as a ,primitive Form”, from which the other types of 
terminations take their origin. . 
A second type of oculomotor termination is the brush ending 
(Fig. 7 and 8), to which we pass from the calyx form through inter- 
mediate gradations. The heavy oculomotor neurite breaks up, before 
reaching the ganglion cell, into two or three main branches, which 
may again subdivide. These forkings are applied to the surface of the 
cell-body, chiefly on the side approached by the neurite, though not 
infrequently the terminal fibrils extend to the opposite side. The tips of 
the ultimate branches are sometimes expanded into small terminal knobs. 
This: , biischelformig” type of ending, as v. Lenhossék has pointed out,
