PLATE 3. All figures, except 80, 34, and 35, are of cross-sections, and all are of Armblystoma unless otherwise indicated.
Fig. 24. Through somite 18 of the right side of a young adult about 60 mm. long. xx 78.
Fig. 26. Through « primary and a secondary mesonephric unit from the left side of a larva 25 mm. long. x 188.
Fig. 20. Through a primary and secondary mesonephric blastula from the eighteenth somite of the right side of a larva 24 min. long. x 850.
Fig. 27. Section of a primary, a secondary, and a tertiary unit from somite 18 of the right side of a larva 25 mm. long. x 105.
Fig. 28. Rana. Section of a mesonephric unit from the right side of the body. The same unit is reconstructed in Figure 30, a dotted line in this figure indicating the level of the section shown in Figure 28. x 410.
Fig. 29. Rana. A section showing a tertiary blastula stil! connected with the Malpighian body of a secondary unit, from the right side of the body. xx 410.
Fig. 30. Rana. A dorso-median view of a wax reconstruction of four mesonephric units and the Wolffian duct of the right side of the body. For a drawing of a cross-section of the most posterior of the four units, sce Figure 28.
Fig. 31. Larval I. A cross-section through the first pronephric nephrostome of the left side of a larva 23 mm. long. x 36.
Fig. 32. Larval II. Section passing immediately posterior to the first pronephric nephrostome of the right side of a larva 25 mm. long, xx 48.
Fig. 38. The third section behind that shown in Figure 32. x 48.
Fig. 31, 35. Two drawings of a wax reconstruction of a mesonephric tubule of left side of the body of a larva 16 min. long. Figure 34 is the anterior aspect; Figure 35, the ventro-median. x 120.
Fig. 36. Larval III. Through the first pronephric nephrostome of the right side of a larva 21.6 mm. long, showing the fundament of the anterior Müllerian evagination. xx 147. Note. — By oversight of the lithographer the nuclei of the tubules are left unshaded.
