Batsch’s Nautilus margaritiferus leaves nothing to be desired as a representative of 
those varieties of Vaginulina legumen which have the septal lines thickened and 
embossed by exogenous deposit of clear shell-substance. The group is equally well typified 
by d’Orbigny’s Modele No. 54, Vaginulina elegans, but the former name has the priority. 
The primordial chamber of such specimens is frequently armed with a stout spine, as 
shown in Costa’s figure ( loc . cit.) 
Neither in the recent nor the fossil condition are the limbate varieties of the genus 
so common as those with non-limbate sutures. The former seldom occur except in 
company with the typical Vaginulina legumen, and there are no data by which their 
separate distribution can be satisfactorily determined. 
Vaginulina bruckenthali, Neugeboren (PL LXVI. figs. 18, 19). 
Vaginulina bruclcenthali, Neugeboren, 1856, Denkschr. d. k. Akad. Wiss. Wien,- vol. xii. p. 98, 
pi. v. fig. 10, a-d. 
The broad compressed specimens, figs. 18, 19, with thick clear septal lines, and 
with one or, more frequently, two short pointed spines at the primordial end, correspond 
well with Neugeboren’s drawings of this strikingly distinct variety. 
Vaginulina bruckenthali has only been found living at a single locality, — off Raine 
Island, Torres Strait, 155 fathoms. 
The fossil specimens which serve as the basis of the original description were obtained 
from the Miocene of Ober-Lapugy, in Transylvania.

Vaginulina linearis has the same morphological characters as the typical Vaginulina 
legumen, but the surface of the test is more or less decorated with raised longitudinal
