REPRODUCTION AND DEVELOPMENT OF Dromiciops gliroides (MARSUPIALIA: MICROBIOTHERIIDAE) IN TEMPERATE RAINFORESTS OF SOUTHERN CHILE
The reproductive biology of Dromiciops gliroides is described from five females collected during spring (October, December 1984) in southern continental Chile. Developmental morphology of intra-uterine embryos (October litters) was examined by microscopic analysis and compared with morphological att...

The reproductive biology of Dromiciops gliroides is described from five females collected during spring (October, December 1984) in southern continental Chile.

Intra-uterine embryos demonstrate ontogenetic features characteristic of altricial neonates, which migrate from the urogenital opening to the marsupium in order to complete the later stages of development.
