XXVIII. — On a Collection of Fishes from the Island of 

 Marojo, Brazil. By G. A. Boulenger, 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 Pard Museum, v/ith 

 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.
