EXPEDITION AXTARCTIori: HELGK 



The number of species from several of the dredgings is considérable, and one of the 

 most interesting hauls of Bryozoa, that lias ever been made is the one on October i8 th , 1898, 

 from Tangles (Faubert) Mil when the large total of 55 species was obtained. The largest 

 number recorded from any Challenger station seems to hâve been 3o. 



Besides the gênerai literature of the subject, the chief works to be consulted are :

There are also lists by MacGillivray, Whitelegge and Hamilton, of Bryozoa, from 

 Australia and Xew Zealand ; further, descriptions of fossil Bryozoa by Maplestone are now 

 appearing in Trans. Roy. Soc. Victoria. 



The literature of the Bryozoa, in un the southern hémisphère, is by no means so 

 extensive as that of the Arctic région, but on the other hand, being, for the greater part, 

 more récent, the descriptions are fuller and more complète. 



This is the first time, that a collection of Bryozoa lias been brought for description 

 from within the Antarctic circle ; though since I commencée! the stucly of this Belgica collection, 

 a few, and for the most part poor spécimens, were brought back from the Antarctic by the 

 Southern Cross Expédition, and thèse hâve been described bv Kirkpatrick ('). 



The species as given by Kirkpatrick are Porc/la Hyadesi Jullien ; Inrersiu/a nutrix 

 [ull. ; Schizoporella hyalina L., and var. discreta; Schizoporella Eatoni Busk; Smittia Landsboroeii 

 Johnst. ; Idmonea organisants d'Orb. ; Lichenopora canaliculata Busk; Alcyonidium flabelliforme
