Morphological studies of the vagina and cervix from females of several species of Pseudomys (pseudo-mice) and Notomys (hopping-mice) have shown marked interspecific differences. In females of all four species of Pseudomys and in N. cervinus there was a relatively thin walled, dorsoventrally flattened, vagina with a large lumen, longitudinal epithelial folds, and conspicuous fornices. By contrast, in females of N. alexis and N. mitchelli the vagina had a much smaller lumen, few or no folds, minute fornices, but a well developed muscle coat. The cervix of the Pseudomys females was a conspicuous fibrous structure, rich in collagen, with two canals throughout its length. In N. cervinus females it was smaller and the two canals, although separated by a median septum for much of their lengths, joined just before the external os. In N. alexis and N. mitchelli females the cervix was much less extensive, its boundaries could not be discerned externally, and, histologically, it was more cellular and less fibrous. This variation in morphology of the female reproductive tract appears to complement that of the excurrent ducts, accessory sex glands and external genitalia of males of these species of Australian murid rodents.
对几种伪鼠属（伪小鼠）和荒漠跳鼠属（跳鼠）雌性动物的阴道和子宫颈进行的形态学研究表明，种间存在显著差异。在所有四种伪鼠属动物以及荒漠跳鼠属的鹿色荒漠跳鼠的雌性中，阴道壁相对较薄，背腹扁平，管腔较大，有纵向上皮褶皱和明显的穹窿。相比之下，在荒漠跳鼠属的亚历克西斯荒漠跳鼠和米切尔荒漠跳鼠的雌性中，阴道管腔要小得多，褶皱很少或没有，穹窿微小，但肌层发达。伪鼠属雌性的子宫颈是一个明显的纤维结构，富含胶原蛋白，全长有两条管道。在鹿色荒漠跳鼠雌性中，子宫颈较小，两条管道虽然在大部分长度上被中间的隔膜隔开，但在子宫外口之前汇合。在亚历克西斯荒漠跳鼠和米切尔荒漠跳鼠雌性中，子宫颈范围小得多，其边界在外部无法辨别，并且在组织学上，它细胞更多，纤维更少。这些澳大利亚鼠科啮齿动物雌性生殖道形态的这种变化似乎与雄性的输出管道、附属性腺和外生殖器的变化相互补充。
