Webster (1961) and Webster and Webster (1975,1977) con- tend that these cells are homologous with the Henson's cells as described for all other mammal species studied. Lay (1972) ques- tioned this identification and noted simi- larities to Deiter's cells. The identification of these cells was seemingly resolved by Henson et al. (1983). They presented a va- riety of data which distinguish a previously undescribed population of cells in a number of mammalian taxa and named these the tectal cells. To bring the terminology ap- plied to the supporting cells of Dipodomys, Microdipodops, and Perognathus by Web- ster into compliance with that used for other species, Henson et al. (1983) suggest ". . that the canopy [Henson's cells of Webster] . . represents an elaboration of the tectal cells and the cells on which they rest perhaps represent what we have called tunnel floor cells rather than cells of Claudius. Thus, the first row of Henson's cells would lie along the outer margin of the ; In the sec-.
