them an intact upper jaw as was the case with the monstrum, 
mentioned under 5. , 
Now and then the two local destroying processes are united. Then 
comes a massive fissure and the monstrosities appear, as described 
under 4 i.e. synotia with anophthalmia, aprosopia and agnatia. 
The series of the different eyclopian deformities is joined to that 
of the synotian deformities. In this series one case is most remark- 
able, ie. if the local destroying process, commencing at the first 
branchial arch spreads so far proximalwards that the upper jaw 
totally falls ont. 
Then the eyes are going to meet each other in the mid-line, while 
the maxillar part of the orbit is lost. Then also two eyes are found 
in a four eye-lid ring, but they are no longer placed in an orbit. 
In that case there is found a cebocephalic form of cyclopia, with a 
complete nose above the eyes, and a complete rhinencephalon. 
To me it seems even possible that the local destroying process 
may spare the first branchial arch, only destroying the upper jaw. 
In such a case there results a cyclopia, perhaps always the cebo- 
cephalic form, but without loss of the ethmoid bone, with a com- 
plete rhinencephalon and without synotia.
