NATrRAL SCIENCES OF PHILADELPHIA. 53 



In the case of the Bouvardia a similar law -was seen. Tlic most 

 vigorous stems, or, as they would technically be called, woody 

 axes, produced the female flowers. 



Prof. Cope made some observations on a Batrachian of the 

 coal measures, Saiu^opleiira 7'einex, Cope. A specimen more per- 

 fect than the type recentl}' obtained by Prof. Newberry, exhibited 

 posterior limbs such as had been ascribed to the S. pectinata. 

 The vertebrai posterior to this point were perfectly preserved, and 

 supported the remarkable processes to the end. 



He also stated that the Oestocephalus ampjhiuminus was dis- 

 tinct, and was furnished with branchial arches of branchihyal 

 bones, for the support of external gills.

Prof. Leidy made the following remarks on Tsenia medioca- 

 nellata. Recentl^^, one of our ablest and most respected practi- 

 tioners of medicine submitted to my examination a tapeworm 

 which had been discharged from a young man, after the use of 

 the Aspidium filix-mas. The physician, in giving an account of 

 the case, stated that he had previously treated the patient for 

 another affection, in which raw-beef sandwiches had been pre- 

 scribed for food. After looking at the worm, I remarked that it 

 appeared to be the Tsenia mediocaneUata, a species which I had 

 not before seen, and added that the patient had probably become 

 infected from a larva swallowed with the raw-beef sandwiches. 

 The specimen consisted of the greater part of the worm, broken 

 into several pieces. Including some lost portions, it was estimated 

 to have been upwards of thirty feet in length. Unfortunately, the 

 head proved to be absent ; but, so far as characters could l)e ob- 

 tained from the specimen, in the form of the segments, position 

 of the genital orifices, and the condition of the ovaries, it agreed 

 with the description given of T. mediocanellata, rather than with 



1871.]
