PLATE 1 
EXPLANATION OF FIGURES 
1 Section of epidermis perpendicular to the surface of the body from the 
region of the dorsal edge of the tail, showing the arrangement of the cells in 
layers, the cuticular margin, mitosis, and the distribution of pigment in ordinary 
epidermal cells, in highly branched chromatophores and. in pyramidal cells. 
Kleinenberg; Ehrlich’s haematoxylin and eosin. > 267. 
2 Epidermal chromatophore containing a densely stained protoplasmic 
mass. Zenker; Ehrlich’s haematoxylin and eosin. X 340. 
3 Portion of epidermis from the edge of the tail with a pyramidal pigment cell 
discharging on the surface. Kleinenberg; Ehrlich’s haematoxylin and eosin. 
x 340. 
4 Pyramidal pigment cell, with cytoplasmic and nuclear inclusions, in a 
vacuole of the epidermis. Kleinenberg; Ehrlich’s haematoxylin and eosin. 
x 340. 
5 Section of epidermis perpendicular to the surface of the body from the 
side of the tail, showing a leucocyte lying within a club cell. Gilson; Ehrlich’s 
haematoxylin and eosin. X 340. 
6 Section of integument perpendicular to the surface of the ventral region of 
the body showing epidermis, dermis, subcutaneous connective tissue, skeletal 
muscles, pigment, elastic fibers (in black), mucous glands, and a mature granular 
gland in median longitudinal section. Somewhat diagrammatic. Kleinenberg; 
Weigert’s resorcin-fuchsin and van Gieson’s picro-fuchsin. X 73.
