active food particle is to be engulfed. The beak-like front is 
flexed, the sedate teg part dilated and, with the aid of the 
cilia, formed into a trap from which usually the only escape is: 
down the pharynx. The pharynx itself is short and conical, 
lacking the curvature so conspicuous in the same part of L. ros- 
_ tratum Ebr. 
The sarcode is not noticeably vacuolar as it is in the Ehren- 
bergian species. few scattered lacunz at times appear pos- 
_ teriorly, but the Sagi seven trabecular ns i common with 
L. rostratum I have not observed. Neither has a contractile: 
vesicle been positively Sistineaished - a spheial vacuole is 
quite etry lesiage present in the posterior body half, but it has 
not been seen to pulsate. 
The iiclet of the type species are described as numerous, 
scattered throughout the body, and connected together by a 
funiculus, to which nucleoli are ‘often laterally attached. Suc 
a complicated arrangement I have been unable to detect in a 
vorax, even after the use of reagents. Here the nucleus seems. 
to be sarten of two, ve a nucleolated, eas 
nodules, without a connecting funi 
taking place, deliberately pulled themselves asunder. The 
body is at times able to adhere to the glass slide or other a 
port, and it here took advantage of that power, clingin 
mass of dirt while the separating portion forcibly pulled a Mes 
sarcode thread from the parent's body, and continued its efforts. 
until the thread snapped. The following description probably 
contains the essential specific characters 
xodes vorax, n. sp.—Body very flexible and elastic, elon- 
oe flattened, from three and one-half to four times as long as. 
road, anteriorly somewhat curved to the left-hand and ending 
in a beak-like apex, posteriorly evenly rounded, somewhat 
apertng and attenuated ; adoral groove wide; pharynx tubular, 
conical and straight ; cilia confined to the ventral surface and 
ee throughout the fine longitudinal striations, those at. 
the posterior extremity being somewhat more conspicuous, a. 
row of slightly larger cilia bordering the adoral groove; dorsal 
surface, under high amplification minutely granulate ; marginal 
hispid setze projecting sub-horizontally from the left-hand mar- 
in, somewhat removed from the right-hand dorso-lateral bor- 
de er and becoming more perpendicular as they approach the 
anterior extremity; parenchyma pale brownish-yellow, seldom 
conspicuously vacuolar ; contractile vesicle (?) single, in the 
posterior body-half; nucleus double, sub-central, each part 
spherical and nucleolated, a funiculus not apparent ; numerous.
