Taxonomic remarks: Egger, in 1857; described Globigerina dubia from the Miocene of Germany; this species appears to be a moderately high spired form with a small and almost closed umbilicus. In 1901, Rhumbler realised that forms obtained from recent seas and referred to "dubia"" by Brady (1884) and Flint (1899) were distinct from Egger's species; as Rhumbler stated, they are larger, with thicker and rougher walls and with a broader umbilicus in which the relict parts of many of the primary apertures of the last whorl can be observed. In consequence, he proposed as new the species Globigerina eggeri putting Brady's ""Challenger"" specimens in full synonymy and illustrating his description with a reproduction of Brady's illustrations.
Although Brady referred to his illustrations (1884, pl. 79, figs. 17a-c) as being of ""a bottom specimen"" (note the use of the singular) our studies of Brady's material have disclosed that actually three separate and different specimens were drawn by Brady's artist, A. T. Hollick. The slide (Challenger Collection B. M. (N. H.) Registered No. ZF.l482 from Challenger Station 300, depth 1375 fathoms, North of Juan Fernandez) contained six specimens; it was marked in Brady's handwriting as ""fig. 17."" Amongst these specimens, one had a broken dorsal side but its umbilical view agreed with that illustrated by Brady (1884) as fig. 17b. The specimen illustrated as fig. 17a is characterised by an irregular series of chambers in the penultimate whorl and was also present in this slide ZF.1482. No specimen could be found which clearly matched Brady's figure 17c. Dr. C. G. Adams and Miss C. Underwood agreed with us in these identifications; consequently, the specimen illustrated by Brady (1884) as figure 17a (not figures 17b and 17c) has been isolated and re-registered in the British Museum (Natural History) as specimen number 1959 .5. 11.741.<br> 
The three specimens illustrated by Brady and referred to by Rhumbler (1901) stand as syntypes of the species Globigerina eggeri Rhumbler. Rhumbler designated no type locality for his species, stating that it occurred in the North and South Atlantic and also in the North and South Pacific oceans from 56° N. to 46° S. latitude. Brady (1884) mentioned no specific locality for his specimens, but the specimen we have isolated falls within the geographical limits recorded by Rhumbler. This isolated specimen (1959.5.11.741) is hereby designated the lectotype of Globigerina eggeri Rhumbler 1901. [Banner & Blow 1960]
