In addition to the foregoing dates recorded in the new system, several 

 others recorded either as Period endings, or Calendar Round dates, or 

 in the ukahlay katunob, were deciphered elsewhere. 



Period Ending dates: 



Chichen Itza Temple of the Tun 10, 2 Ahau 

 Initial Series. 



Tuluum Stela 1 Tun 10, 7 Ahau 



Calendar Round date:

 hypothesis mentioned elsewhere. Previously this had been regarded 

 as being 10.2.9.1.9 9 Muluc 7 Zac, ^. e., the Initial Series on the under 

 side of the lintel. The contemporaneous date, however, is doubtless 

 that recorded on the front of the lintel and is as given above. 



Through the accidental discovery of an important missing fragment 

 of the Tuluum stela, it has been possible to date that monument as 

 10.6.10.0.0 7 Ahau 18 Yaxkin — that is, just one cycle later than its
