The fact that Sponge-Names appear under at least three heads 

 does not facilitate the student in making out certain questions, one 

 looks for in the nomenclator. Once we see after a Sponge-name : — 

 Spong.; another time, Prot., another time, Pol. 



Finally I call attention to the fact that innumerable times the 

 name Schmarda is printed in stead of S c h m i d t. 



As I stated before, I know the great difficulties of compiling such 

 lists — but one must agree that the Sponges are treated in a t o o super- 

 ficial way. 



After having made the above given lists, I suggested to some of my 

 Colleagues to look also through Scudder's Nomenclator, with respect 

 to their special group. 



Dr. W. Giesbrecht kindly furnished the follo>ving list of 

 omissions with regard to Copepods.
