974 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



mimicated to- the fish. When growing and in good condition, however, 

 it always has a brownish or yellowish-brown color. The species on cod- 

 fish was always colorless, and yet it seemed to be alive and in good con- 

 dition, and I am inclined to reject my first belief that the form was a 

 discolored Glococopsa crepidinum^ but think it rather an undescribed 

 species of Sarcina. My stay at Gloucester being short, and having other 

 things which demanded my attention, I was unable to make any con- 

 tinued observation on this curious form, which may be described as 

 follows : 



Sarcina ? morrhu^ n. sp. Cells colorless, cuhoidal, 5-8'^ in diameter, 

 united in fours and surrounded hy a thin hyaline envelope. Colonies 10-20™ 

 in diameter, formed by division of the cells in three dimensions. Colonies 

 heaped together in irregularly-shaped, lobulated masses. 



Hab. — On putrifying codfish, in company with Clathrocystis roseo-persi- 

 cina, Gloucester, Mass., September, 1878.
