dashed down by the short flagellum, is seized by one or more 
of the pseudopodie projections and drawn into the body. With 
this form the food, thrown down by the action of the short 
flagellum, enters at any part of the surface, usually near the 
base of the flagella, where the part opens, the mucilaginous in- 
vestment and the adherent spicules moving outwardly on what 
appears to be a delicate cuticle, a wave-like outflow of the 
endoplasm surrounds the particle and draws it into the body 
enclosed in a large drop of water. In length these cuticular 
spicules are little shorter than the short flagellum. 
The nucleus is indistinct and presumably centrally placed, 
although it was not positively identified. The two contractile 
vesicles pulsate alternately, and are distinctly apparent. The 
animalcule is shown in fig. 1, Plate III.

The lorics, as is so common with those of the Vaginicolina, 1% 
this change of tint, is neither young nor mature, for the pos 
terior half has assumed a translucent, chestnut hue while ther 
maining portion is as colorless as when first secreted. Arguing 
from this alteration, it is probable that the chemical composition 
of these sheaths is similar to those of the Vaginicolina,
