for the reception of some abnormal specimens from the Miocene 

 of Messina. He classed them with d'Orbigny's family Stichostegia, 

 regarding them as allied to Glandulina ; but Brady subsequently 

 transferred them to his sixth family Chilostomellidse. At the 

 time of the publication of his Report on the Foraminifera of the 

 ' Challenger ' Expedition, the genus was known only from the 

 single species Ellvpsoidina cllipsoides Seguenza, and Brady's descrip- 

 tion of the genus was accordingly based on this. He states,* 

 " The chambers are elliptical, and each larger than its predecessor 

 as in Chilostomclla ; but their point of attachment instead of being 

 at one side is at the base, and they are all projected symmetrically 

 in one direction, instead of being directed alternately towards the 

 two ends. The aperture is always at the distal extremity, and 

 takes the form of an arcuate or nearly circular slit, either; entire 

 or more communly divided by shelly bridges. From the centre of 

 the superior end of each segment, that is to say, either from the 

 space enclosed by the curved aperture or its immediate neighbour- 

 hood, rises a shelly column of sufficient length to reach to the top 

 of the succeeding chamber. This column is an anomalous feature, 

 to which there is nothing precisely analogous amongst other 

 Foraminifera. It was originally supposed to be a tubular neck 

 serving for the aperture, and the genus was on that account 

 classed with the NodosarintB, but, as I have elsewhere! shown, 

 this has not proved to be the fact, for the orifice occupies an 

 independent position at its base, and the column itself is not 

 hollow, but it is often deeply grooved longitudinally, or even split 

 into two or three parts near the upper extremity." 



In 1894 Mr. E. J. Lechmere Guppy published a paper " On 

 some Foraminifera from the Microzoic Deposits of Trinidad, West 

 Indies," % in winch be figured and described two further species of 

 Ellipsoidina, viz. E. subnodosa Guppy, and E. exponens Brady, M.S.
