of an adult female was loaned by the University of California 

 Museum of Vertebrate Zoology. The uniformity of the material 

 in regard to size is quite sufficient to include all under the one 

 species D. obscurus, which is found in the locality at the present 

 time. 



DENDEAGAPUS, sp. 

 There appear among the grouse remains in the collection a 

 large number of specimens of unusual size. The closest relation- 

 ship seems to be with Dendragapus, from which the form differs 

 in its great robustness and in the slight detail of the head of the 

 tarsometatarsus. The Recent material at hand includes only a 

 female of Dendragapus, hence the range of variation due to sex 

 and age is unknown to the writer. Until further Recent material 

 is obtained the identity of these larger specimens remains in 

 doubt. 



BON AS A UMBELLUS (Linnaeus) 

 This species is at present distributed along the humid coa.st 

 region of the continent as far south as the latitude of the Shasta 

 region. It is however not recorded from localities so far inland 

 in Recent time. It is of interest, then, to find in the Potter 

 Creek Cave two very perfect specimens referable to this species. 



OEEORTYX PICTA (Douglas) 

 This quail is represented by eighteen specimens, all but four 

 of which are from Hawver Cave. Comparison was made with 

 a specimen from the University of California Museum of Verte- 

 brate Zoology and the identity found to be unquestionable. 



LOPHORTYX CALIFOBNICA (Shaw) 

 This species is represented in the Hawver Cave deposits only, 

 but here it is the most abundant of avian species, seventeen 

 specimens of wing and leg bones making the identification 

 complete. 



In number of individuals, the group Gallinae far surpasses 

 all of the others combined. There are in the cave collections 

 some two hundred and seventy individual bird bones that are 

 determinable. Of these one hundred and sixty-eight are assigned
