110 THE NAUTILUS. 



30'. Others were sent b)'- Ensign SafFord, U. S. N. from Maldonado, 

 Uruguay, and Bahia. In this connection attention may be called to 

 the list of shells from Fernando Noronha in the Linnean Society's 

 Journal (Zool. xx, pp. 483-503, 1890) by Mr. Edgar A. Smith of 

 the British Museum. This list is not a long one but the same tend- 

 ency is obvious there, as in our present lists, for the Antillean species 

 to range far southward. Thorough dredging along the coast would 

 doubtless greatly enlarge the lists both of local and Antillean species. 

 In the following list, which is strictly supplementary to that of 1891, 

 some of the species are extended southward from their most southern 

 previously known range nearly three thousand miles ! A few species 

 were sent by Dr. W. H. Rush, U. S. N., in May, 1892, which were 

 dredged in jNIaldonado Bay near the mouth of the La Plata in 3-6 

 fathoms mud. Those belonging to the northern fauna have been 

 added to make the supplement as complete as possible.
