individuals represent a subfamily, the Ciconiinae, which is at 

 present foreign to the region. 



In the following description of these remains it was found 

 necessary to establish two new species. It was considered inad- 

 visable to establish a new genus of stork, although the species 

 maltha, here referred to the genus Ciconia, is intermediate in the 

 sum of its characters between Ciconia and Euxenura. The 

 generic distinction between Euxenura and Ciconia is based 

 largely on external features, and even these features are con- 

 sidered by some students to exhibit insufficient differences to 

 warrant the recognition of the separate genus Euxenura. Con- 

 ceding that the differences between the existing forms are of 

 generic value, the form under discussion would not agree with 

 either genus, and a new genus would be necessary. While there 

 is little question that, were the asphalt stork restored to us in 

 its entirety, it would possibly exhibit characters sufficient for its 

 generic distinction, yet for the sake of simplicity it is referred, 

 in the absence of those superficial characters, to the genus 

 Ciconia. 



CICONIIDAE, STORKS. 



CICONIA MALTHA, n. sp. 



Type specimen no. 11202; cotypes nos. 11237, 12529, 12527, 

 12532, and 12526, Univ. Calif. Col. Vert. Palae. The remains 

 representing this species are somewhat fragmentary on the whole, 

 but some very characteristic parts have been preserved, — namely, 

 the coracoid, tarso-metatarsus, proximal and distal ends of the 

 tibio-tarsus, and half of the furcula. To these parts there was 

 added, through the kindness of Dr. C. 0. Esterly of Occidental 

 College, the middle portion of the beak, including the nostrils. 



Aside from their separation in place in the deposits, the 

 specimens show such duplication as to prove that more than one 

 individual is represented. The homogeneity of characters, how- 

 ever, is sufficient to indicate their specific identity. The size is 

 about the same as that of Euxenura maguari, from which species 

 it differs in the details of each bone represented.
