remarks and the names of 351 species which have been 

 recorded as occurring in that State of the Argentine Republic. 

 A few remarks are added to each of them. 



We can assure the author that much yet remains to be 

 done in Argentine Ornithology, and advise him to examine 

 the Sierras on the western side of Tucuman. He claims to 

 have added 20 species to the previous lists of the birds of 

 the State. 



92. Lonnberg on a Fossil Condor. 



[On some Fossil Remains of a Condor from Bolivia. By Br. Einar 

 Lonnberg. Bull. Geo). Inst. Univ. Upsala, vi. pt. 1 (1893).] 



Among the valuable palseontological specimens brought 

 home by Baron Erland Nordenskiold from the valley of 

 Tarija, in Southern Bolivia, were a complete tarso-metatarsus 

 and the upper and lower ends of the femur of a large bird. 

 These are now described and figured by Dr. Lonnberg and 

 referred to a new species of New-World Vulture allied to 

 the Condor, which it is proposed to call Sarcorhamphus 

 patruus. The age of the new fossil Condor is about that 

 of Mastodon andium, plentiful remains of which are found in 

 the same deposits. 



93. Lucas on some North- American Fossil Birds. 



Notes on the Osteology and Relationship of the Fossil Birds of the 

 Genera Hesperornis. Haryeria, Baptornis, and Diatryma. By Frederick 

 A. Lucas. Proc. U.S. Nat. Mus. xxvi. pp. 545-556 (1 ( J03).] 



The acquisition by the U.S. National Museum of a speci- 

 men of Hesperornis regalis and the loan of some bones of 

 Hesperornis gracilis and Baptornis advena have enabled 

 Mr. Lucas to add a little to our knowledge of these obscure 

 fossil forms. After commenting fully on Hesperornis, he 

 points out that H. gracilis is so different from H. regalis, 

 that it ought to be put in a separate genus, for which the 

 title Hargeria is proposed. Baptornis is stated to be quite 

 distinct from Hesperornis, and more like existing birds. 

 Diatryma is not a Dromieognathinc bird, and may possibly 

 belong to the Stereornithes.
