The student is referred to N. Y. Regents' Reports. Fig. 124 represents two species, one with the spines directed obliquely outwards and in the other erect. They are both from the Hamilton Group. In the Corniferous Limestone we have also two small species of Producta. One of these (Fig. 125) is covered with nodular radia- ting ribs. The other is about the same size as the above but with a smooth tubercular surface. Genus Leptoccelia ? Hall. This genus as described by Professor Hall in the 12th Annual Report of the Regents, published in October or November 1859, seems to differ from CentroneUa only in consisting of species which have the surface ribbed instead of smooth. Professor Hall dates his genus back to 1856, but no description was published until the issue of the 12th Regents' Report and therefore should it be the same as Centro- neUa it cannot be retained, as the latter has the priority. For the present I shall use it provisionally, not having seen the internal structure myself. Leptoccelia? flabellites. (Conrad.) Atyrpa FLABELLiTES. (Conrad.)
