BETOZOA FEOM FKANZ-JOSEF LAND. 165 



1. Ceisia coenuta, var. geniculata, M.-Edw. 



Crista cornuta, var. geniculata, Hincks, Brit. Mar. Polyzoa, p. 419, 

 pi. Ivi. fig. 44. 



All the specimens of Crisia from Franz-Josef Land are 

 only fragmentary, and are without ovieells, so tliat we can add 

 nothing to our knowledge of the genus, but only record the 

 localities. 



There has been a doubt -wY^Qt^xev geniculata should be eonsidere d 

 as a variety or as belonging to another genus {Crisidia), for in 

 C. cornuta the spines are not found to all the zooecia — in some 

 cases to very few. Harmer * however considers, from differ- 

 ences in the ovicell, that C. cornuta and C. geniculata should be 

 specifically separated. In Smitt's and other works the locality 

 for the two varieties is not given separately, and therefore a 

 full list of the distribution cannot be made, but I do not find 

 that this variety has been recorded from Arctic seas.

Although there are no ovieells, I think there can be no doubt 

 that the specimens belong to the species described by Busk. The 

 zoarium is narrow, the zooecia from the two sides being very 

 close together without an intermediate space ; there are about 

 11-17 zocBcia to an internode ; the joints are light ; the free end 

 of the zocEcia is short, and the branches start from the lower 

 zooecia.

3. Ceisia ebuenea {Linn.). 



There are a few fragments from Giinther Sound which seem 

 to be the lower joints of this species. There are about six
