DESCRIPTION PRELIMINARI DEL MORPHOLOGIA DENTAL IN INDIANOS DE PERU.—Le dentes del indianos de Peru es grande. Lor incisores es in forma de pala. Crestas labio-marginal es frequente (pala duple e tres quartos de pala duple). Incisores lateral in forma de barril se trova occasionalmente. Multe molares M¹ ha 4 cuspides, con reduction del magnitude del hypocono in un medietate del casos.

Le molares M2 e M3 monstra hypoconos minus frequentmente. Un medietate del molares M3 ha tres cuspides. Le cuspide de Carabelli in le molar M¹ es infrequente, e generalmente su expression es non plus que intermedie. Le molares M2 e M³ es usualmente disproviste de cuspides de Carabelli. In 70 pro cento del molares Mi, le configuration es Y5; in 30 pro cento, illo es +5. Le molares M2 e M3 frequentemente monstra le configuration +5. Nulle caso de configuration Y4 esseva incontrate. Un protostilido esseva trovate in numerose dentes. In le molares M₁, M2, e M₃, su frequentia amontava a 70, 45, e 13 pro cento, respectivemente.
