 Cysts, usually luuuerous, were found in this host on July 8, 14, 22, 2!), 

 and Augusts. They were found in the nuiscular coats of the stomach, 

 and were of various sizes, from CO mm. to t! mm. in diameter. In 

 all cases they contained wax}^ degenerate tissue which was dark brown 

 or amber colored. One small cyst, less than 1 mm. in diameter was 

 found to contain a minute nematode.

Cysts like those found in J^J. viacidomis were found in this host on 

 July 11, 15, 16, 18, and August 3. In some cases the^^ were most abun- 

 dant in the submucous coat of the stomach; in others they were most 

 numerous in the muscular coats. In the latter case the}^ were as a rule 

 in greatest numbers in the pyloric region, where the dark brown, 

 sometimes almost black, cysts were in sharp contrast with the white 

 tissue in which they were embedded. They are most alnmdant in the 

 large groupers, and evidentl}' represent entozoa which have had a 

 long residence in their host and have either succumbed or migrated. 

 Myderoperca ojnui. 



July 21, two. Large numbers of cysts were also found on the mes- 

 entery and serous coat of the viscera generally. They contained dark- 

 brown waxy degenerate tissue, and varied in size from 2 mm. or less 

 to 20 mm. or more. They were irregular in shape, often nodular, 

 sometimes flattened. No entozoa were foiuid in them. The smaller 

 ones are probably due to nematodes, the larger to cestodes.

July 29, numerous, also on July 31, many. These nematodes were 

 first found in washings from the alimentary canal. It was observed 

 that there were many small cysts in the intestinal wall, with the usual 

 waxy contents. Some of these cysts were crushed under a cover 

 glass and in one of them, a minute nematode, agreeing with the free 

 specimens, was found.

 in water to wliich a little fornuilin had been added.
