300 Scientific. Intelligence, 
in the Quarterly Journal of Microscopical Science, for Jan., 1863, has 
given the most probable solution :—that the jaw figured by Dr. Wallich 
is one of the ges ne or jaws of a pedicellaria of an Echinoderm, allied 
to Amphidotu 
In =o with this subject of the eee of vertebrate 
jaws, we may take occasion to mention the jaws of som 
Annelids, the resemblance of which to Pi of the higher 
animals has not been mentioned by any of Dr. Wallich’s 
critics. In the mouth of the sedbeieis: ne worms of the 
family Aphroditacea, such as Polynoe, Sigalion, and ° 
Acoétes, we find upper and lower jaws, each composed of

extended in such a w ay that they should rest for nearly their w pages 
length, and leave simply a free play for the extremities to reach ow 
yond the head.
