Summary In the adenohypophysis of Cichlasoma biocellatum, which may be divided into a pro-, meso-, and meta-adenohypophysis, seven cell types can be distinguished. Treatment with deionized- and salt water effects three of these cell types. The rostral acidophils, which were proved to produce prolactin by means of an immunochemical method, are distinctly stimulated in deionized water and markedly inactivated in 25% sea-water. The putative ACTH cells, bordering neurohypophysial branches in the pro-adenohypophysis, are moderately stimulated by both treatments. The presumptive TSH cells, which in control animals appear to be very active, do not show marked changes in deionized water; they are strikingly inactivated, however, in salt water specimens.
