. The first forty-one pages of the present work were printed in 

 the spring of 1879, more than a year before work was resumed on the 

 remaining part. Meanwhile numerous additions have been made to our 

 list of sharks, which may be noticed here. A few errors may also be 

 corrected.

Page 7 : Lampetra (Entosplienus}* tridentatns and L. plumbea are per- 

 haps geuerically distinct, as the lingual teeth in the former are pectinate 

 and in the latter obscurely tricuspidate. The diagnosis of Lampetra 

 should be modified accordingly. 



Page 8 : "5. L.epihexodon" and "6. L. astori" should be suppressed, 

 as they are probably identical with E. tridentatus.
