Some drawings were exhibited by Dr. Smith, of the forms pre- 

 gented by the teeth of the species composing several of the above 

 sections, and he remarked that on a future evening it -vvas his in- 

 tention to lay before the Society some further observations upon 

 other groups of the cartilaginous fishes. 



Professor Miiller of Berlin being present confirmed the views en- 

 tertained by Dr. Smith as to the number of divisions -vvhich might 

 properly be made of the family Sci/llium, several of -vi^hich he had 

 already published, as mentioned by Dr. Smith. As to the rank -vvhich 

 these groups should hold in a systematic arrangement, he considered 

 this a point upon \vhich we are hardly in possession of sufficient evi- 

 dence to justify a decided opinion.
