A few other species, such as " Megascoleoc sancta helenas" of 

 Baird, may belong to this genus. A number of forms described by 

 Schmarda 1 as Pericha'ta have been shown by subsequent investi- 

 gators not to belong to that genus as now denned but to Megascolex. 

 Prof. Spencer 2 and Mr. Fletcher 3 described under the name of 

 " Pericliceta" worms which belong to other genera and were only 

 provisionally placed in Perichata. The same may be said of 

 several species described by Prof. Bourne. 4
