BRYOZOA 



9i 



Land, has séries about i mm apart, whereas I hâve a spécimen from Iceland, so named, and 

 one from Station 4g of the Challenger, with the séries about o.6 mm apart. The small fragment 

 from N° gg 1 is rather stouter than the others, but I think it is certainly the same species. 



Habitat. — It occurs frequently in the Arctic, British, Mediterranean and N. Atlantic 

 seas, and has also been found in Australia by MacGillivray &c. According to Busk (Chall. 

 Report) it occurs off the Kerguelen Islands, the Cape of Good Hope, and off Tristan d'Acunha, 

 in the South Atlantic but some of thèse déterminations were made from poor spécimens ; 

 Cape Horn as mentioned above. 



It has been found fossil in the Australian Tertiaries, in the Pliocène of England, Italy &c. 

 According to Manzoni it also occurs in the Miocène of Austria, but the /. gracillima of Reuss 

 from the North Italian Bartonian beds, I now consider should be called /. concava Reuss, 

 though it has sometimes been placed with /. atlantica.

From N° 991 there are two small erect spécimens, with the zoœcial openings on the one 

 face, though on the dorsal surface the zoœcial tubes are equally distinct, and extend for a 

 great length. The spécimens are too small for the détermination to be quite satisfactory. 



Whether the lineated dorsal surface, formed by smaller tubes is a character of generic 

 importance is uncertain. In Idmonea it is gênerai, also occurring on what I hâve considered 

 to be Filisparsa irregidaris of Meneghini, as well as on Filisparsa tiibulosa Busk ; and when this 

 structure is absent, as. in the présent form, there seems to be a closer approach to Tubulipora. 



The genus Tervia Jullien seems to be the same as Filisparsa d'Orbigny. 



The zoœcial tubes, in the Antarctic spécimens, project free for a considérable distance, 

 and sometimes the ends are in pairs.

The Antarctic spécimens are thicker than most of the Mediterranean ones, and the 

 interior diameter of the zoœcia is about o.i6 mm -o.i8 mm . In one spécimen there is a piriform
