papille extend a little way up the dorsal and ventral surfaces 
of the utricle; and a few, according to Warming, may be 
found in the upper part. This upper region is covered by 
many transverse rows, one above the other, of short, closely 
approximate hairs, pointing downwards. These hairs have 
broad bases, and their tips are formed by a separate cell. 
They are absent in the lower 
part of the utricle where the 
papille abound. The neck is 
likewise lined throughout its 
whole length with transverse 
rows of long, thin, transparent 
hairs, having broad bulbous 
(fig. 80) bases, with similarly 
constructed sharp points. They 
arise from little projecting 
ridges, formed of rectangular 
epidermic cells. The hairs vary 
a little in length, but their 
points generally extend down 
to the row next below; so that 
if the neck is split open and 
laid flat, the inner surface re- 
sembles a paper of pins,—the 
hairs representing the pins, and 
the little transverse ridges re- 
presenting the folds of paper. 
through which the pins are 
thrust. These rows of hairs are 
indicated in the previous figure

part of the utricle; those in the 
upper part are formed of two cells, which are much elongated 
downwards beneath their points of attachment. These two- 
celled papille apparently correspond with the bifid process 
in the upper part of the bladders of Utricularia. The narrow 
transverse orifice (0, fig. 29) is situated between the bases of 
the two spiral arms. No valve could be detected here, nor
