1) The arrangement of these parts of the upper jaw was only clear to us, after 

 we had examined Xcnopocciliis. This explains the different interpretation by one 

 of us, when describing the genus We believe now, that the bone described 

 there (see fig. 98) as intermaxillary, is an artefact, caused by two symmetrical 

 cracks in the real intermaxillaries.
