PSOLIDJE. 



It was first discovered on the coast of Norway by Mul- 

 ler. The genus ranges to the Indian seas. The Psoitis 

 tenama of Jaeger and Lesson should form the type of 

 another genus, distinguished by its twenty tentacula. 

 The genus Cuvieria of Peron should be united with Psolus. 

 The family of Psolida is a very natural group.
