relationship is founded merely on linguistic analogies and on the appar- 

 ently common origin of a number of words. But these facts can be 

 taken as conclusive only if supported by common anthropological char- 

 acteristics and also by partial community of uses and customs. Physi- 

 cally, the Cunas are strikingly distinct of the Guaymies and the Costa 

 Rican Indians, and both stocks offer none but general racial likeness to 

 what is left of the original Chibchas. In the opinion of Professor Pittier 

 the origin of the Cuna-Cuna has to be looked for elsewhere than in the 

 interior of Columbia, and the Guaymies, Valientes, Bribri, Terrabas, 

 Sumos, etc., are more likely to be the remnants of a primitive autoch- 

 tonous stock. Pittier's talk was illustrated by lantern-slides and by 

 objects collected among the Chocoes and Guaymies.
