544 MESSES. E. HERON-ALLEN AND A. EAELAND ON THE 



has associated with species of doubtful specific value in many genera. It will therefore 

 be not uninteresting to note those species recorded in the TMC. 1826 from those 

 localities, which we have been able to identify from the Kerimba Archipelago. 



By the courtesy of Dr. Etienne Loppe (Curator of the Musee Fleuriau de Bellevue 

 at La Rochelle) we have been permitted to examine the bottles of material from Mada- 

 gascar and from Reunion (He de Bourbon) presented to that museum by d'Orbigny 

 himself. These consist of pure gatherings of Jmpliistegina lessonii with a small 

 admixture of OpercuUna complanata and its \Sixieiy granulosa. The varietal differences 

 among the individuals in this material are so great that it is not surprising that d'Orbigny 

 made five different species out of 0. complanata (TMC. p. 281) and eight species out 

 of A. lessonii, all the forms drawn by him for the " Planches inedites " being fully 

 represented. The latter were studied and diagnosed by Dr. Fornasini in a paper to 

 which we have referred in dealing with the genus Amiikistegina. 



1. Pavonina flabelliformis (Maur.), TMC. p. 260. no. L 



2. Textularia coimnunis (Maur.), TMC. p. 263. no. 27. A neat form of T, sagittula, Defranee, 



ideutifiert by Brady with d'Orbigny's T. cleperdita (O. 1846, FFV. pi. xiv. figs. 23-25). 

 We have not found the types in Paris or La Rochelle*. 



3. Bulimina madayascariensis (Mad.), TMC. p. 270. no. 17. The types are not at present 



forthcoming, but the sketches for the unfinished " Planche inedite " show it to be Bulimina 

 elegantissima, var. seminuda Terquem. 



4. Rotalia communis (Mad.), TMC. p. 273. no. 29. The type in Paris appears to be Puhi- 



nulina rqmnda (F. & M.) t (c/. F. 1898, IIFI. p. 249, fig.). 



* It may be observed that the type-specimens of d'Orbigny's 'Tableau Methodique' in Paris are mounted 

 upon glass slips backed -with blue paper and enclosed in small tubes, which in turn are fastened upon wooden 

 slips, and are kept in drawers in the laboratory of the Director of the Musee de Paleontologie. They have 

 evidently been overhauled more than once, and perhaps many of the types have strayed away into the drawers 

 containing the types of the Cuba, Canaries, S. America, and Vienna collections. These we have not yet been 

 able to examine. When therefore -we say that the types are not forthcoming, the probability is that they are 

 merely disarranged, and that when we can go through the entire collection we shall be able to restore many 

 strayed TIIC. tj?pes to their places in the cabinet. The types or co-types at La EoeheUe have been mounted 

 in sealed slides by C. Easset, who described them in the 1885 vol. of the Societe des Sciences Naturelles de la 

 Charente Inferieure (pp. 153-173) with a poor photograph of the " Modeles." These slides are for the most 

 part overgrown with mycelium and fungus. Several of the Paris types are also fungus-grown. As an " offset " 

 to the missing types we have noted no fewer than thirty -three species of various authors (including d'Orbigny) 

 among the TMC. types, showing that a serious disarrangement has taken place. We grieve to record that 

 the original tubes of d'Orbigny's material, which were kept in the cellars of the Musee de Paleontologie, were 

 flooded in the rising of the Seine in the year 1912 and many of the labels are lost. Fortunately, however, when 

 Prof. Schlumberger went over the collection during his Directorate of the Musee, he put labels inside many of 

 the bottles (including the Madagascar samples), and we owe it to him that the loss to science was not greater 

 than it is.
