Ix the last number of the Annals, Vol. 1 II., p. 464, the writer stated, 

 that, so far as he was able to ascertain, certain of the bones, which he 

 described in his paper upon " The Hyoid Bone in Mastodon Ameri- 

 canus," had not as yet been found or described. His attention has 

 been called to the fact that J. I), (iodman in the year 1825 pub- 

 lished a i)aper, entitled " Description of the Os Hyoides of the Masto- 

 don," which appeared in the Journal of the Academy of Natural 

 Sciences of Philadelphia, ^"ol. IV., p)). 67-72, accom])anied by a 

 plate giving outlines. This paper by Mr. Godman had been en- 

 tirely overlooked at the time of the publication of the i)a])er in the 

 .\nnals of the Carnegie Museum. Mr. Godman describes the basi- 

 hyoid, which from his description and figure apparently agrees well 

 with the specimen described by the writer, and one of the thyro-hyals. 

 He also describes a ceratohyal. The latter bone was not found in 

 connection with our specimen, which, however, in all respects, aside 

 from this, is evidently a very much more perfect specimen than the 

 one described bv Godman. 



The Trustees of the British Museum have kindly presented to the 

 Trustees of the Carnegie Museum one hundred and sixty-five bound 

 volumes, being the publications of the Natural History Department of 

 the British Museum, which up to the present time have not been 

 represented in the library of the Carnegie Museum. The Trustees and 

 the Director of this museum desire publicly to acknowledge their great 

 indebtedness for this signal act of generosity on the part of the authori- 

 ties of the British Museum. An almost complete set of the publications 

 of the British Museum (Natural History) is now accessible to stu- 

 dents in the reference library of the Carnegie Museum. 



Efforts are being made in the library of the Carnegie Museum to 

 secure as rapidly as possible complete sets of all the publications of 

 learned societies, to which reference must be made by students of 

 science. The process is necessarily somewhat slow, but we hope 

 within a few years to be able to accomplish our purpose of furnishing 

 scientific investigators in western Pennsylvania with all the apparatus 

 of a literary sort which they may require for the prosecution of 

 their studies along biological lines. \\'hen this is accomplished it 

 will no longer be necessary for students to undertake pilgrimages to
