352 UTRICULARIA MONTANA. (Cuap. XVIII. 
previously mentioned species probably relates to the capture 
of aquatic animals. 
It seemed to me an interesting question whether the 
minute bladders of Utricularia montana served, as in the 
previous species, to capture animals living in the earth, or 
in the dense vegetation covering the trees on which this 
species is epiphytic; for in this case we should have a new 
sub-class of carnivorous plants, namely, subterranean feeders. 
Many bladders, therefore, were examined, with the following 
results :— 
(1) A small bladder, less than x; of an inch (‘847 mm.) in diameter 
contained a minute mass of brown, much decayed matter; and in this, 
a tarsus with four or five joints, terminating in a double hook, was 
clearly distinguished under the microscope. I suspect that it was a 
remnant of one of the Thysanoura. The quadrifids in contact with 
this decayed remnant contained either small masses of translucent, 
yellowish matter, generally more or less globular, or fine granules. In 
distant parts of the same bladder, the processes were transparent and 
quite empty, with the exception of their solid nuclei. My son made 
at short intervals of time sketches of one of the above aggregated 
masses, and found that they continually and completely changed their 
forms; sometimes separating from one another and again coalescing. 
Evidently protoplasm had been generated by the absorption of some 
element from the decaying animal matter. 
(2) Another bladder included a still smaller speck of decayed brown 
matter, and the adjoining quadrifids contained aggregated matter, 
exactly as in the last case. 
(3) A third bladder included a larger organism, which was so much 
decayed that I could only make out that it was spinose or hairy. The 
quadrifids in this case were not much affected, excepting that the 
nuclei in the several arms differed much in size; some of them contain- 
ing two masses having a similar appearance. 
(4) A fourth bladder contained an articulate organism, for I distinctly 
saw the remnant of a limb, terminating in a hook. The quadrifids 
were not examined. 
(5) A fifth included much decayed matter apparently of some 
animal, but with no recognisable features. The quadrifids in contact 
contained numerous spheres of protoplasm. 
(6) Some few bladders on the plant which I received from Kew 
were examined; and in one, there was a worm-shaped animal very 
little decayed, with a distinct remnant of a similar one greatly decayed. 
Several of the arms of the processes in contact with these remains 
contained two spherical masses, like the single solid nucleus which is 
properly found in each‘arm. In another bladder there was a minute 
grain of quartz, reminding me of two similar cases with Utricularia 
neglecta.
