 fish, birds, lice from seals, 3 worm-eaten planks taken from schooner 

 Melissa D. Bobbins, shark, fish, seals, fungi, etc. From Major T. B. Fer- 

 guson was received a specimen of Barn-owl, and from C. H. Townsend 

 15 specimens of Menopoma and eggs. Mr. Townsend made an explora- 

 tion of Swan and Grand Cayman Islands, and has already forwarded a 

 collection of birds, concerning which Mr. Ridgway, curator of birds, 

 makes the following statement: 



Swan Island. — The collection from this place embraces 31 species, of 

 which 22 are land birds. Of the latter 17 are migrants from Eastern 

 North America 5 Coccyzus seniculus is West Indian and Central Ameri- 

 can ; Columba leucocephala belongs to the coast of Honduras and some 

 of the Greater Antilles ; Mimocichla rubripes (of which a good series 

 was collected) is identical with the Cuban species, instead of being that 

 found on Grand Cayman (M. ravida Cory); Contopus albicollis Lawr? 

 (2 specimens) is probably identical with a Yucatan species, and Dendro- 

 ica vitellina Cory, is identical with a species found elsewhere only on 

 Grand Cayman. The only new form is a Butorides, allied to B. virescens, 

 but altogether darker in coloration, and perhaps different enough to be 

 considered specifically distinct. 



The water-birds include five specimens of the following: Tringa 

 maculata, Ereunetes pusillus, Totanus flavipes, Porzana Carolina, Sula 

 cyanops, S. piscator, S. sula, and Fregetta aquila. 



Grand Cayman. — Mr. Townsend's collection from this island contains 

 12 species, including 5 of the 13 new species obtained by Mr. Cory's 

 collector, viz : Certhiola sharpei, Dendroica vitellina, Centurus cayman-
