688 ZOOPHYTES. 



Plate 61, fig. 6, zoophyte, natural size, partly in outline; 6 a, one 

 of the polyps, expanded, and another contracted, natural size. 



The Feejee Islands. Exp. Exp. 



The oblique circlet of tentacles and very exsertile polyps appear to 

 point to a different genus from the ordinary Sertularise. The outer 

 tentacles of the circle were a little longer than those on the inner side, 

 and the apices of the latter were hardly recurved. The breadth of 

 the plume was about one and a half inches; the pinnules were placed 

 alternately, and the rachis was correspondingly a little zigzag. The 

 plate represents the zoophyte as it was figured on the spot, untouched 

 since, as the specimen was afterwards misplaced. 



PASYTHEA GRACILIS. (Dana.} 



P. sex polyporum acervis seriatis instructa; caliculis extus spectantibus, 

 basi non inflatis. 



Polyps in successive clusters of six; calicles opening outward, not 

 inflated at base. 



Fig. 11, page 25, zoophyte, enlarged. 



Gulf-weed, Atlantic Ocean. Exp. Exp. 



This little species is near the quadridentata of Lamouroux, but has 

 six, instead of four, polyps to each cluster, and the calicles are not 

 enlarged below. It was obtained and figured by Dr. C. Pickering. 



FAMILY III. CAMP ANULARID^. 



Hydroidm gemmis persistentibus, polypis dongato-tubulatis, caliculis 

 pedicellatis ; reproduction, Tubularidis affinia.
