an inch in height, and the same in breadth, at the occipital 
spine, and others of a less size in the line of the lamhdoidal 
suture and at the mastoid angle. In the specimen 301, 
marked Chilian, from Valparaiso, the os wormianum at the 
occipital spine is 2 inches broad and 1 inch in height, and 
there is great irregularity in the line of the lamhdoidal 
suture. In this skull a remarkable horizontal depression, 
above the superciliary ridge in front, is observed. Five of 
the skulls are marked Peruvian, from Huacas, near Lima, 
and in which no trace of ossa wormiana can be seen, thus 
confirming, in a very conclusive manner, the observations 
of Dr Archibald Smith. In the month of February last, Dr 
Smith read an interesting communication on this subject to 
the Society of Antiquaries of Scotland, entitled " Observa- 
tions on the Inca and Yunga Nations, their Early Eemains, 
and on Ancient Peruvian Skulls." 
He then exhibited six specimens of Peruvian skulls dis- 
interred from ancient burying-grounds, and in only one is 
there to be found a trace of ossa wormiana^ nor is there to 
be seen the slightest appearance of a furrow marking a line 
of obliteration. The specimens are now preserved in the 
Museum of the Antiquaries here. It may therefore be con- 
sidered as satisfactorily established, that ancient Peruvian 
skulls, although occasionally found with wormian bones of a 
considerable size in the line of the lamhdoidal suture, are 
more frequently destitute of this peculiarity, and that the ex- 
istence of a so-called interparietal or supraoccipital wormian 
bone can in no respect be regarded as a special character- 
istic of the race,
