when quiescent the axis of the body, when in a condition of equilib- 
rium, assumes an angle of about eighty degrees with the surface. 
The adhesive organs near the mouth now become functional. Up to 
this time the light area on the yolk is prominent, and enables one to 
watch the singular rotation of the larva. The head now begins to 
widen rapidly, and the light area on the belly becomes darker. The 
tail-fold soon becomes very thin, and bordered all round by a delicate 
edging of black pigment. The larve cease to rotate on the fourth 
day, and no longer take up their angular position at the surface of the 
water, and now behave very much like the larve of Rana.’ They are 
now very heavily pigmented over the whole of the body; the light 
area over the space where'the yolk was formerly placed has disap- 
peared, and the larve are now black as seen from above. —J. A. RYDER.
