rence of it was favoured. As this suture is so rare, the fact that it 

 is found in this colony seems to me to be of some importance. 

 Meanwhile we must not forget that the skulls of man and monkeys 

 have been examined by far most accurately and that large collections 

 of them exist. The other groups of the mammals contrast very 

 much with them. So it would seem to be more or less natural that 

 the sutura parietalis has been found almost exclusively with man and. 

 monkeys. Too few skulls of the other groups of the mammals have 

 yet been compared and examined accurately. Within a short time 

 I hope to revert more in detail to this subject and also to mention 

 some skulls of monkeys, in which I could show the sutura parietalis. —
