PARKER and 1. RUPERT JONES, in one of their earlier papers on the " Nomencla- ture of the Foraminifera" J, make a passing allusion to them. Amongst their notes on the fossil forms of Alveolina, especially those of the Nummulitic Period, they say, " The largest we have seen was collected in Persia by the late Mr. W. K. LOFTUS, and is three inches long and an inch and a half in diameter. " The two sentences quoted appear to comprise all that has hitherto been written on the subject of the present... paper. 25. A portion of Mr. LOFTUS'S geological collection was presented, some time after his decease, to the Museum of the Natural History Society in Newcastle ; and finding amongst other things a number of examples of this supposed Alveolina, I asked, and readily obtained, permission of the Committee to make such preparations from them as might be requisite for the elucidation of their structure. 26. A very slight examination by means of transparent sections convinced me that, not- withstanding a general similarity in external contour, the internal structure was distinct in many important characters from either of the previously known genera of fusiform FORAMINIFERA.
