4 Annals of the Carnegie Museum. 



saurs. As the Director pointed out in his paper read before the 

 Paleontological Society on December 31, 1914, there is no positive 

 certainty as to the head which belonged to Apatosaurus. No speci- 

 men has as yet been found with the skull so situated in relation to the 

 cervical vertebrae as to remove the question from the field of con- 

 troversy. The association made by Professor Marsh, which has 

 generally been accepted by those who have not had opportunities to 

 closely study the subject, appears to have been in the nature of a 

 guess. There is a good deal of reason to think that Professor Marsh 

 may have been in error. 



Mr. and Mrs. Otto E. Jennings have returned from the State of 

 Washington where they spent the summer making botanical collections 

 for the Museum. They were highly successful and the result has been 

 the acquisition by the herbarium of many thousands of specimens 

 representing in the neighborhood of fifteen hundred species of the 

 flowering plants of that State. Collections were made by Mr. Jen- 

 nings on the high mountains, in the arid interior, and along the coast. 

 Incidentally Mrs. Jennings succeeded in collecting quite a number of 

 insects, some of which are entirely new to our collections. 



Dr. Arnold E. Ortmann has twice visited the drainage basin of the 

 Tennessee, and has made very large collections both in its upper 

 affluents and in the broader reaches of the river below Knoxville. 

 He reports that this Museum now possesses as the result of his re- 

 searches the largest and most perfect collection of the mollusca and 

 Crustacea of eastern Tennessee in existence in any museum. His 

 studies, based upon these extensive collections, will enable him to 

 clear up a number of disputed questions as to synonymy and will 

 pave the way for the preparation of a monograph similar to that upon 

 the moUuscan fauna of the Ohio River which is in course of preparation. 



We have acquired by purchase from Mr. Samuel M. Klages a very 

 large collection of the birds of Venezuela, which adds a multitude of 

 species of South American forms to our collection. From the same 

 source we have also secured a considerable collection of the lepidoptera 

 of the same country.
