Abstract
In this Second Part the Marsipobranch type of skeleton will be described in several stages, as far as my materials go; afterwards, I hope to be able to show in a Third Part some of the organs in the act of transformation, the specimens for which I am now expecting. In the present paper I shall describe :— A. The skeleton after transformation.
a
. In the adult
Petromyzon Jluviaiilis
..
b
. In one-third grown
P. marinus
.
c
. In newly metamorphosed
P. marinus.
d
. In very small (not quite transformed) young of
P. marinus.
B. The early embryo of
P. planeri
; and C. The larval form (or Ammoccete) of
P. fluviatilis
, ready for transformation.*
