ANNUAL KEPORT OF THE 



mended. Two of the chief treasures of the Museum have been 

 mounted by Mr. J. H. Emerton, and are shortly to be placed on 

 exhibition. These are the type-specimen of Titanichthys agas- 

 sizi N. and a practically complete skeleton of Dinichthys terrelli 

 N., from the Cleveland Shale of Ohio. The disassociated parts 

 having been variously interpreted, it is hoped that this novel 

 attempt to show them in their natural position will prove 

 instructive. 



With the exception of some Proboscidean remains saved from 

 the fire of the Boston Museum and presented to this Depart- 

 ment, very little has been added to the Mammalian or Reptilian 

 series. They remain, however, in excellent condition, and con- 

 tain not a few choice specimens which eventually will be 

 mounted. Arrangements are being made with a Kansan col- 

 lector for spending part of the present summer in the field, 

 mainly in search of fossil mammals and reptiles.
