MUSEUM OF COMPARATIVE ZOOLOGY. 5 
the selection of representative species. The floor case shows the 
cast of Jguanodon bernissartensis, from the Wealden of Belgium, 
as the central feature, with casts and portions of the skeletons of 
Dinosaurs and of Vertebrates, other than Fishes, around it. The 
Fishes and a few other Vertebrates occupy the wall cases on the 
north side of the room, while the Invertebrates will be displayed 
in the cases on the south side, and the large table cases on the 
east and west sides. Considerable wall space, outside of the 
cases, is used for many of the more bulky Vertebrates. To 
the African faunal room there has been added, by purchase from 
Rowland Ward, a fine male of the South African Ostrich, Struthzo 
australis, and a magnificent male Hippopotamus from the Mosello 
River, Zambesi; the latter, an excellent example of modern taxi- 
dermy, is nearly maximum size for the species, and with the 
Giraffe received in 1903, makes an effective exhibition of two 
characteristic African Mammals. The principal other additions 
to the exhibition collections consist of the Reptiles mounted by 
the Museum preparator, Mr. George Nelson; of these, twenty- 
eight have been added, the more notable being a group of the 
Mexican Heloderma, H. horridum; one of the Bahama Iguana, 
Cyclura baeolopha, and a fine Boa, B. constrictor. For the Boa 
and the Iguanas we are indebted to the interest of Mr. Thomas 
Barbour ; the Helodermas were obtained in eben: from the 
Bierichn Museum of Natural History. 
The U.S. Fish Commission Steamer “Albatross,” under the com- 
mand of Lieut. Commander L. M. Garrett, U.S. N., was placed at the 
disposal of Mr. Agassiz, and was occupied with deep-sea work in 
the Hastern Tropical Pacific from October, 1904, until March, 1905. 
Mr. Agassiz was accompanied by Prof. C. A. Kofoid of the Uni- 
versity of California, Mr. H. B. Bigelow, and Mr. Magnus Wester- 
gren of the Museum. The cruise extended from San Francisco 
to Panama, from Panama to the Galapagos, and thence to Aguja 
Point. From Aguja Point, the “ Albatross” worked towards the 
western edge of the Chili-Peruvian Current, then east through the 
Milne Edwards Deep to Callao. Leaving Callao on December 34, 
Kaster Island was reached on the 15th. Considerable shore 
work was done at Easter Island, and on January 3, 1905, the 
“ Albatross” arrived at Wreck Bay, Chatham Island, Galapagos. 
From Wreck Bay, the cruise continued to Manga Reva, and from 
that place to Acapulco, which was reached February 24th. Mr. 
Agassiz’s letters, written during the voyage, have been published
