I have l)ceu enable! to uleutify li}l;\-oiie (51) species, thirteen 

 (13) of which I Hnd to be new to science. Out of tliesc llfty-one 

 species Professor Cope had on a former occasion pubhshed ac- 

 counts of ten of thcni — two of which were new — in addition to the 

 thirteen the j^resent writer has been enabled to describe. Among 

 other places, those described by Professor Cope appeared in an 

 article contributed by him to the 'American Naturalist' in 

 November, 1SS9, and so will not be especially dv\elt upon here. 



Abundant remains o'i ^^chmophoms occidcntalis occur in this 

 remarkable collection of some 1500 specimens, and to a lesser 

 degree' do we find the fossil bones of Colymbus holbcelli^ C. 

 aiiritits (.?), C. nigricollis caUfornic7is^'A\-\i\ Podilyinbus podi- 

 ccps. Thus far, it is strange to say, no remains of any species of 

 Loons have been met with, nor any large extinct Divers allied 

 to them. Nor were any of the Alcidce discovered. This is a 

 significant fact, which to the student of the migration of animals 

 during tertiary time, may prove interesting. 



Gulls apparently were abundant, and I have been enabled to 

 identify Larus anyentatits sinithsnnianus^ Lams Philadelphia^ 

 Xema sabinii, and another which was most probably L. cali- 

 fornictis. There were at least two extinct Gulls, and they were 

 of moderate size, and probably niit very uidike existing forms^ 

 which I have named Larus robustus and Lams orcgonus. 



The list of Laridce is completed by Sterna elegans (.?), 

 Sterna forstcri (.?), and Hydrochclidon irigra surinatneiisis. 



Steganopodes appear to be limited to that big Comorant already 

 described by Cope, the Phalacrocorax macropns^ and to the prob- 

 able occurrence of the Pelican, Pelecanus erythrorhynchiis^ oi 

 which I found only a part of an ulna in the collection, not quite 

 enough in my opinion to absolutely prove its existence in the 

 geological horizon under consideration. Nevertheless the bone 

 belonged to a Pelican, which was not fusca^ and as the other 

 species is abundant on those Oregon Lakes at the present writing 

 it was most likely the other species, that is, P. erythrorhynchus . 



As they are today. Ducks, Geese, and Swans were very plenti- 

 ful, and with Init one or two exceptions they are all identical with 

 existing species. I found more or less abundant fossil remains of 

 Lophodytes cnciillatns^ Anas boschas^ A. americana^ A. carol- 

 itiensis^ andyl. discors^ and the remains of another Teal which I 

 believe to be A//as cyanoptcra. Spatula clypcata was a very
