First division of the Monera . 
Gymnomonera. 
Monera without a resting condition, and without formation 
of a covering. 
The freely moving condition of the Moner is interrupted 
by no resting condition with formation of a covering. 
Genus I. — Protamceba, Haeckel. 1 
Haeckel, ‘ Generelle Morphologic,’ 1866, vol. i, p. 133. 
Generic character. — A simple shapeless protoplasm body 
without the formation of vacuoles, which protrudes simple 
processes, not ramifying or anastomosing, and which repro- 
duces itself by fission. 
Species. — Protamceba primitiva, Haeckel. 
Plate X, fig. 25 — 30. 
‘ Generelle Morphologie,’ 1866, vol. i, p. 133. 
Protoplasm-body of 0'03 — 005 mm. diameter, continually 
varying in form, with one or several (3 to 6) peripheral 
pseudopods. Processes short, rounded, obtuse, finger-shaped, 
at most as long as the diameter of the central body. 
Locality. — A pond of fresh water in Tautenburg Forest, 
opposite Hornburg, near Jena. 1863 and 1865. 
Genus II. — Protogenes, Haeckel. 5 
‘ Zeitschr. fiir. wissenscli. Zool.,’ vol. xv, 1865, p. 360. 
Generic character. — A simple shapeless protoplasm-body 
without the formation of vacuoles, which protrudes ramifying 
and anastomosing processes, and reproduces itself by fission. 
Species. — Protogenes primordialis, Haeckel. 
‘ Ueber den Sarcodekbrper der Rhizopoden,’ 1. c., p. 360, 
pi. xxvi, figs. 1, 2. 
Protoplasm-body sometimes contracted globularly r , from 
0T — 1 mm. diameter (1. c., fig. 1); sometimes extended and 
flattened out, of an irregular outline, of 3 — 4 mm. diameter 
(fig. 2) ; pseudopods exceedingly numerous (over a thousand), 
very fine, with very numerous ramifications and anastomoses. 
Locality. — Mediterranean, near Nice, 1864.
