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

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

 sections, and he remarked that on a future evening it was 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 which might 

 properly be made of the family Scyllium, several of which he had 

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

 these groups should hold in a systematic arrangement, he considered 

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

 dence to justify a decided opinion.
