truding the cuticle at both ends of the animalcule’s body, as 
shown in figure 8, where the inverted pharngeal rod-fascicle is 
also exhibited. The pharnyx is often forced to remain in this 
inverted position until the endochrome within the frustule is 
digested out, and the empty plant is extruded from the body, 
as the diatom once in this tight place is not moved until the 
digestive processes are completed, the pharynx, in the mean- 
time, having no room to rotate back to its normal position. But 
so voracious is the creature that it often attempts to engulf ad- 
ditional frustules even while the pharynx is upside down, an 
attempt which is of course always abortive. When there is 
enough space before the extrusion of the empty frustule, always 
after its expulsion, the return movement of pharyngeal rotation 
is voluntary. On account of the creatue’s voraciousness I have 
elsewhere named it Chilodon vorax. 
The anal aperture is on the animalcule’s dorsal surface, as 
shown in figure 9, where it has been represented considerably 
out of its proper position. - It should be much lower and nearer 
the posterior extremity. Indeed, the figures are, at best, little 
more than diagrams. 
AMERICAN SOCIETY OF MICROSCOPISTS. 
D. 8. KELLICOTT, SECRETARY. ~ 
ih has been determined by the Executive Committee of the 
American Society of Microscopists that the next annual 
meeting shall be held at Chautauqua, N. Y., commencing Aug. 
10th and continuing at least four days. 
The place and time are regarded as favorable for a large 
and profitable annual reunion. Chautauqua is delightfully sit- 
uated, readily accessible, the rates of travel to the resort are 
greatly reduced, besides the thousands of people residing there 
are in pursuit of recreation and knowledge. 
The week of meeting is near the end of the usual summer 
vacation and one week before the meeting of the American As- 
sociation for the Advancement of Science at Buffalo. 
As early as June 1 circulars of information concerning the 
general sessions, the working session, railway fares, board, etc., 
will be sent to all members and others desiring them. 
Letters addressed to the secretary will be promptly and 
cheerfully answered.
