Natural History of East Finmark, 107 



Genus Harmeria, gen. nov."^ 



Zooecia ovate, thin, glassy, hyaline, with a scutiform or 

 ovate space on the front, distinctly circumscribed by a raised 

 line, within which the surface is punctate. Oral aperture 

 semielliptic ; lip straight in the younger stage, but after- 

 wards overhung by a suboral collar-like process with more 

 or less developed rostrum. No visible ocecia. No avicularia. 



Type, Hanneria scutulata = Lepralia scutulata, Busk. 



The mode of development in this genus is very remark- 

 able. Tlie zooecia radiate from a centre, and the polyzoary is 

 in the form of a round patch. It is only at the centre that 

 the zooecia attain their complete development and are fully 

 exposed, so that their unpunctured bases are entirely visible ; 

 with succeeding growth additional zocEcia are continually 

 interposed laterally, and each zooecium is smaller in size 

 than the one which precedes it, and at the same time over- 

 laps its successor, so that at the circumference of the zoarium 

 they are seen to be heaped up one upon another. The 

 suboral rostrum differs much in size and sometimes assumes 

 great development.

On stones and shells of Buccinum between tide-marks at 

 Vadso, and Nordgaard records it from the Laminarian zone 

 at Nordkyn. I also have it in my collection from 0-1 

 fathom, Smeerenberg Bay, Spitsbergen (F. A. Smitt). 

 These last specimens are on Laminaria, and it would seem 

 to be essentially a tide-mark or very shallow-water species. 

 Busk^s West Greenland types were " on fucus " ; Smitt 

 speaks of the specimens he has seen as being " in regione 

 algarum baud frequentem,^' and as '' Laminarise affixam^" 

 but Bidenkap gives 16-20 metres.

 arrangement of the rest of the Cheilostomata, and shall only 

 refer to existing genera. I had already written the greater

 admirable work in the study of the Polyzoa.
