Dujardin's observations/ and in another place " he says that 

 they touch often, Imt are not amalgamated, and that one can 

 follow them with difficulty until they separate again. But both 

 here and in the Vienna Monograph ^ he falls back upon Dujardin 

 for his general descriptions of pseudopodia. 



It will be seen by what has gone before that d'Orbigny fully 

 and generously admitted the work of Dujardin, and it is not true 

 that (as the severe Carpenter says) * he ignored Dujardin's genus 

 Groraia in all his subsequent writings. On the contrary, he calls 

 attention to it in the Cuba Memoir,^ both in the Introduction and 

 the work itself, and again (practically in the same words) in the 

 Vienna Monograph.® 



The citation of these notes of d'Orbigny in the Cuba Memoir 

 brings us naturally to the group of Memoirs published by him 

 in 1839-40, of which the Cuba Memoir was probably, and is 

 generally taken to be, the first in order of date. 



VII.— The Cuba Memoie.^ 



The order of date in which the four Memoirs dated 1839-40 

 were actually published is wrapped in some degree of confusion, 

 and can only be arrived at from casual notes to be found scattered 

 through them, and from the synonymies of some of the species 

 recorded in them. There is no doubt that immediately on his 

 retur^ from South America (February 2, 1834) he addressed him- 

 self to his 'great work on his voyage, which was not completed 

 until 1847. He quotes the earlier volumes in the Cuba IMemoir,^ 

 and later, in his Introduction, he says, " I am publishing at this 

 moment three other local faunas — (1) that of the Canary Islands 

 . . . ; (2) that of South America in my ' Voyage dans I'Amerique 

 Meridionale {une partie spcdale) ' ; (3) fauna of the white chalk 

 of the Paris Basin." ^ The Cuba Memoir is quoted in the Canary 

 Islands Memoir ; he says ^° that he is in course of publishing it, 

 but as he quotes it by page in his synonymies ^^ it was clearly
