Abstract

The fine structure of the dental enamel was intensively examined in the Family Callitrichidae.Leontopithecus rosalia has the nonserial pattern, butCallimico goeldii andSaguinus midas appear more or less modified from the typical nonserial pattern asSaimiri sciureus has (see Figs. 1 & 5). On the other hand,Callithrix jacchus andCebuella pygmaea attain to the primitive stage of the multiserial pattern (see Figs. 4 & 6). So far as the structural patterns of the dental enamel are concerned, a serial trend is confirmed in the Callitrichidae; extending from the genusLeontopithecus through the generaCallimico andSaguinus to the generaCallithrix andCebuella.

The genusSaguinus shows extremely wide interspecific variation in the fine structure of the dental enamel, ranging fromS. leucopus with the most primitive features toS. bicolor with the most advanced (see Figs. 2 & 3). The rows of enamel prisms are slightly twisted mesiodistally in the former species, but strongly folded in the latter. This reflects transitional stages from the nonserial pattern to the multiserial. As a whole, however, the genusSaguinus is still regarded as nonserial. Thus, there is a slight, but important gap between the genusSaguinus andCallithrix, as shown by the decussation of clusters (see Fig. 5), as well as by other characters.
