44 EEPORT OF NATIOKAL MUSEUM, 1915. 



important contribution to the reserve series that has been received 

 in some years. It contains material from every part of the world 

 except the West Indian region. In addition, Mr. Henderson also 

 turned over to the Museum, as a part of the results of the Tomas 

 Barrera expedition to Cuba, which he mainly financed, approxi- 

 mately 10,000 specimens of invertebrates, of which 8,000 were mol- 

 lusks, including many species new to the collection. In this 

 exploration he was assisted by Dr. Carlos de la Torre, of Havana, 

 and Dr. Paul Bartsch. 



Eight separate collections of much scientific value were transferred 

 by the Bureau of Fisheries. The more prominent of these were 

 clypeastroid sea-urchins to the number of 767 specimens from cruises 

 of the steamer Albatross in 1887, 1902 and 1906, identified and de- 

 scribed by Dr. H. L. Clark in the Memoirs of the Museum of Com- 

 parative Zoology; the crinoids from the Philippine expedition of 

 the steamer Albatross^ 1907-10, worked up by Mr. Austin H. Clark; 

 the Asteroidea, including types and^cotypes, from cruises of the 

 steamer Albatross in 1891 and 1899-1900, under the direction of 

 Alexander Agassiz, described by Prof. H. Ludwig in the Memoirs of 

 the Museum of Comparative Zoology; more than loO specimens of 

 parasitic copepods, embracing types and cotypes, studied by Dr. 

 Charles B. Wilson and the results published in the Proceedings of 

 the National Museum; about 9,000 specimens of crustaceans taken 

 in connection with the biological survey of San Francisco Bay by 

 the steamer Albatross in 1912-13; and about 800 specimens of mis- 

 cellaneous marine invertebrates collected by the steamer Albatross 

 in 1914 during a further survey of San Francisco Bay and an inves- 

 tigation of the halibut banks off Washington and Oregon. 



Special acknowledgments are due to the Carnegie Institution of 

 Washington for splendid series of corals and mollusks obtained 

 through the efforts of Dr. A. G. Mayer and his staff of collaborators 

 at the Tortugas Marine Biological Laboratory. Among the most 

 noteworthy was a set of 1,000 specimens of corals from the Bahama 

 Islands and Florida, including, with few exceptions, all of the speci- 

 mens planted by Dr. T. Wayland Vaughan and used as the basis of 

 his study of their rate of growth. In some respects, according to 

 Dr. Vaughan, this collection is unique and the most interesting in 

 existence. Additional material consisted of about 300 specimens of 

 corals, representing some 75 species, from Murray Island, Australia, 

 together with many bottom samples from the same locality, collected 

 by Dr. Mayer, who also contributed 1,000 land shells and 30 corals 

 from the Bahama Islands. During the botanical expedition of Dr. 

 J. N. Eose to South America, he and Mrs. Rose secured over 200 

 specimens of invertebrates for the Museum in northern Chile.
