f The species thus marked are in my own collection. The Tunicata and Cepha- 

 lopoda are on the authority of Mr, W. Thompson. The testaceous forms are chiefly 

 extracted from Mr. Jefi"rey's recent " Gleanings " in the ' Annals of Natural History.' 

 A few also together with the Nudibranchs from Forbes and Hanley. For Odostomia 

 conspicua and Ovula patula see ' Natural History Review,' vol. vi. " Proceedings 

 of Societies," pages 79 and 85.
