Ceylon Marine Entozoa. 133 



broad at base, when elongated. Very active in springing ; it 

 can adhere to sand or stones. 



This is, I believe, the second species known of Gosse's new 

 genus Peacha, I have dedicated it to the original describer 

 of the genus. Mr. Gosse's description led me to observe this 

 species very closely, although I was at first induced to con- 

 sider it a species of Edwardsia. The inferior orifice admits 

 of the passage of a moderate sized probe. The oral orifice 

 has not that foliated appendage described by Gosse. It is 

 for him to determine whether this is a generic character. 



ZOANTHURA. 



Zoanthura, sp. — green disc. 



Z. Mammalifera. — brown disc. 



Being now on the eve of embarkation for India, I have only 

 time to notice the above two species of Zoanthura, which I trust 

 will be described by other naturalists who may succeed me. 



CEYLON ENTOZOA. 



Order. Parenchymata. 



This order includes all those Entozoa which have the body 

 filled with a parenchyma, or pulpy matter, either in a cellular 

 tissue, or simply in the cavity, in which there is no alimen- 

 tary apparatus to be discovered, except a few canals, which 

 carry nourishment to all these parts. The ovaries are also 

 imbedded in the parenchyma ; there is no abdominal cavity, 

 no intestine, and no vent ; and the signs of a nervous system 

 are few and doubtful.— Cuv.
