Abstract

In a comparative study of the branchial epithelium of fishes we find the occurrence of three distinct types and seven subtypes of intra‐epithelial glands which are in intimate association with the branchial epithelium of fishes.

These glands have been classified according to their morphological patterns, cytoplasmic content and other features dealing with structural complexity.

Although these structures arrange themselves in a graded series which become increasingly more and more complex, there does not appear to be any definite correlation between the structural complexity of the glands, and the apparent evolutionary history of the fishes.

We conclude from the characteristic arrangement, relationships, and specific staining reactions that these structures are intra‐epithelial mucous glands.
