XXVII.—On a Collection of Fishes from the Island of 
Marajo, Brazil. By G. A. BouLenGcER, F.R.S. 
A LARGE and important collection of Fishes formed on the 
island of Marajo has been sent to me for identification by 
Dr. E. A. Goeldi, the Director of the Paréd Museum, with 
permission to retain types and duplicates for the British 
Museum. It seems to me desirable to publish a list of all the 
Fishes identified, together with the descriptions of two which | 
require the establishment of new species. One of the most 
valuable examples in the collection is the Lepidosiren pre- 
viously recorded by Dr. Goeldi, and which, I am glad to add, 
I have been allowed to incorporate in the British Museum 
collection.
