Research on Reptiles and Amphibians 79 



can lizards with which he dealt. As indicated below, two of 

 these papers have been published; a third is still in manu- 

 script. The latter is entitled "A Review of the Genus of 

 Lizards Holbrookia Girard." Mr. Schmidt has also pub- 

 lished two short papers this year completing his work on the 

 West Indian collections of the Museum. It is hoped that 

 the Whitney South Sea Expedition will continue to make 

 herpetological collections which will serve as a basis for a 

 more extensive report than the preliminary notice given in 

 Copeia by Mr. Schmidt. 



Mr. C. L. Camp's research on the Classification of the 

 Lizards was continued this year with considerable success. 

 Much work was done on the musculature of the hyoid ap- 

 paratus and the throat, which has proved unexpectedly 

 interesting. 



The Senior Assistant Curator has presented for publica- 

 tion the first part of his "Phylogeny of the Salientia," dealing 

 with the osteology and myology of nearly half of the known 

 genera of frogs and toads. A new classification of the Salien- 

 tia is given and a critical examination of the structural basis 

 of classification is made. A number of shorter papers. were 

 published by him during the year. These deal chiefly with 

 the several South American collections which he has well 

 in hand. 



The splendid Barnum Brown collection from Abyssinia and 

 Somaliland, as well as the first shipment of reptiles and am- 

 phibians from the Third Asiatic Expedition, are already 

 studied in part. They will form the basis of taxonomic, dis- 

 tributional, and morphological investigations. 



The following technical papers were published in 1921 by 

 the Department staff: four in American Museum Novitates, 

 two by G. K. Noble, and two by K. P. Schmidt; three in the 

 Bulletin of the American Museum of Natural History, one by 

 G. K. Noble, and two by K. P. Schmidt; two in the Annals- 

 of the New York Academy of Sciences, by G. K. Noble; and 

 three in Copeia, one by G. K. Noble, one by G. K. Noble and 

 C. H. Pope, and one by K. P. Schmidt. 



In addition to the above, the Senior Assistant Curator 

 published three popular articles in Natural History and one in 

 Father and Son Library.
