BRYOZOA 



tative of S. ternata var. gracilis ; Smittia antarctica nov. has some points of resemblance to 

 Pseitdoflustra palmata Sais, of the Arctic, but is quite distinct, so that no species only known 

 in the Arctic or neighbouring seas has been found in the Antarctic. This however is taking 

 it for granted, that there is sufficient justification for making a new species of Megapora 

 hyalina, which was done from small spécimens, and may be open to question. There are 

 some species common to high northern latitudes and to the Antarctic, but also found in 

 intervening régions as Micropora coreacea Esper., Hippothoa divancata Lamx., H. distans 

 MacG., Smittia rcticulata MacG., Idnionea atlantica Forbes, Entalophora proboscidea M. Ed., and 

 thèse may ail be called cosmopolitan. I hâve dealt elsewhere with the Cyclostomata, and 

 refer to many of them being closely allied to cosmopolitan species. 



When the description of the Antarctic Bryozoa was completed, and nine plates were 

 drawn, I went to Paris in order to examine the collections of d'Orbigxy, described in the 

 «Voyage dans l'Amérique méridionale», and the récent forms described in the «Paléontologie 

 Française » ; as well as those of Jullien, relating to the Cape Horn Expédition, as it was 

 important to make the comparison with the fauna of the southern extremity of South 

 America and the Falkland Islands as complète as practicable. 



The collection of d'Orbigny, both récent and fossil, is in the Paleontological department 

 of the Muséum d'histoire naturelle in Paris, and is for the greater part in comparative] v 

 good order, though a portion having been kept ail thèse years in open boxes a few things 

 in the course of time hâve been changed or removed. It is however évident that d'Orbigxy 

 has often given descriptions from small and very imperfect spécimens, which we should 

 now pronounce to be indéterminable. 



Julliex's collection in the Zoological department, was brought to the Muséum some 

 time after his death, and as he had been ill for many years, the collections may not hâve 

 been left in working order. At any rate, fossils and récent spécimens were mixed together in 

 great confusion, so that I spent a week in separating them into two or three groups, beforc 

 I could study the Cape Horn spécimens. Much time is still required to get this enormous 

 amount of material into order, but as a commencement has been made, it wdl now be 

 easier for any one to arrange the parts. Besides the slides and spécimens named byJuLLiix 

 and described in vol. VI of the « Mission scientifique du Cap Horn », there was a drawer 

 of unnamed material, as well as spirit spécimens in several jars, which presumably Jullien 

 had never seen. My examination of the encrusting forms has not been exhaustive, nor did 

 I open ail the jars where I could make the requisite déterminations without doing so. I hâve 

 however been able to add 3o species to the 56 mentioned by Jullien, and no doubt there 

 are additions yet to be made. 



Certain modifications, as to distribution &c, hâve been necessary in conséquence of 

 my visit to Paris ; and thèse will be apparent in the text, as well as some additions resulting 

 from my examination of an important collection from the Bancs des Aiguilles, South Ahïca, 

 in Jullien's collection. The Eastern Australian Bryozoa hâve now been thoroughly studied 

 by MacGillivray and others, and a number of South African species hâve been described 

 in the « Challenger Reports » and scattered papers, but neither the South African nor South 

 American fauna hâve been thoroughly examined. From South Africa I hâve a manuscript 

 list of 107 species. I hope shortly to publish some notes on the d'Orbigxy and Cape Horn 

 collections.
