ENNEA (HUTTONELLA) SEATONI, sp. nov. (Plate XXIX. figs. 15-19.) Shell cylindric, whitish, narrowly rimate ; whorls 11, convex, sutures deep, very slightly decreasing in size upwards, the upper two smooth, shining, the others finely but prominently ribbed, the last expanded and free towards the aperture ; aperture oval, nearly vertical; peristome thickened inwards, the columellar margin with a deep circular incision extending to the suture of the penultimate whorl, above this cavity the margin of the peristome runs back into the interior of the aperture, forming a strongly developed lamella, opposite which there are two obscure teeth on the inner part of the peristome well within the aperture. Length f inch. Hab. Tenasserim, limestone rocks east of the Mooley-it mountain near the Siam frontier. Only a single example was found when visiting this mountain with Col.

By far the most numerous remains met with in the fossiliferous deposit of Samos explored by me in 1888 and 1889 appertain to a new member of the family Giraffidse. The rich materials at my command furnish satisfactory knowledge of this new form, and at the same time suggest novel considerations concerning the various forms already described. Falconer and Cautley, in describing a fossil Giraffe discovered in the Siwaliks, wrote as follows :-"The Giraffe has hitherto been confined to a single species, and has occupied an isolated position in the order to which it belongs. It may be expected that, when the ossiferous beds of Asia and Africa are better known, other intermediate forms will be found, filling up the wide interval which now separates the Giraffe from the antlered ruminants, its nearest allies in the order according to Cuvier and Owen " 2. This was written 47 years ago. 1 Communicated by the President. 2 H. Falconer and Capt. P. T. Cautley," O n some Fossil Remains of Anoplo-therium and Giraffe, from the Sewalik Hills," Proc. Geol.
