PERIGONIMUS COCCINEUS. 97 



P. (?) MINIATUS, T. Strethill Wright. 



ATRACTYLIS MINIATA, T. S. Wright, Observations on Brit. Zooph., Micr. Journ. 

 (N. S.) iii. 48. " 



ZOOPHYTE tree-like, branches given off at an acute angle 

 from the stem, crooked, wrinkled, but not ringed, coeno- 

 sarc yellow ; POLYPITES with 8 alternate tentacles, oral 

 cavity silvery, lining of the stomach bright red-lead 

 colour; REPRODUCTION unknown. 



THIS zoophyte forms little "gnarled, shrubby" tufts about 

 an inch high. " The bright-yellow colour of the polypary 

 (ccenosarc) at once strikes the eye, which is also arrested 

 by the gaudy colour of the minute polyps. These appear 

 to be maTked by two broad, internal patches, one corre- 

 sponding to the buccal cavity, of a dense silvery white ; the 

 other to the cavity of the stomach, of a brilliant reddish- 

 orange.^ (Wright.} 



This species can only be placed provisionally until the 

 reproductive bodies have been observed.

ATRACTYLIS COCCINEA, T. S. Wright, Observations on Brit. Zooph., Ann. 

 N. H. for Aug. 1861, viii. (ser. 3) 130. 



STEMS about a quarter of an inch high, of a rich pinkish 

 cream-colour ; POLYPITE fusiform, set at an obtuse angle 

 to its stalk, not retractile*, crimson or pink, with 8 alter- 

 nating tentacles, four long and four short ; REPRODUCTION 

 unknown. 



THE stems are given off from an open network of milk- 



* Sars makes the non-retractility of the polypite one of the characters of 

 his genus Perigonimus. But forms, otherwise most nearly allied, differ in 

 this respect ; and the character is certainly not of sufficient importance to 

 justify their separation.
