of a limestone cliff, from which they had evidently but recently 

 been separated, as other vertebrae and ribs were seen protruding 

 from the rock close to them. The remains in the solid rock of 

 the cliff were worked out in the fall of 1901 by Mr. H. W. 

 Furlong, and were found to include part of a left limb of 

 exactly the same dimensions as the right limb in the loose slab. 

 The coracoids, and many of the cervical vertebra?, were found 

 with the left limb. There can be no doubt that all of these 

 remains belong to the one animal. 



The vertebra 1 comprise individuals belonging to the cervical 

 and dorsal regions. It is not certain that the series is complete, 

 but judging from the gradual increase in size toward the posterior 

 end, there are few, if any, gaps. 



The most anterior individual is deeply biconcave and is, 

 therefore, possibly neither atlas nor axis. On the other hand 

 the large size of the intercentrum between it and the succeeding 

 individual indicates that it was close to the anterior end of the 

 column. It is not probable that it was further back than the 

 third. 



The following are the measurements of some of the best 

 preserved centra and arches in the series. The position of the 

 7th, 11th, 17th, and 35th vertebras could not be determined 

 with absolute certainty, but is in each case not more than one or 

 two vertebras removed from the point in the column to which it 

 is here referred. The height of the 1st and 3rd centra is given 

 without and with (h) the inferior apophysis. Measurements in 

 millimeters.
