different from that of the fossiliferous pebbles in the bed." Further, 

 even supposing the correctness of Mr. Oldham's theory, that the 

 fossiliferous pebbles are concretionary nodules, it does not at all 

 explain the presence of this small special fauna in a distinct bed by 

 itself. Mr. Medlicott asks the following pertinent question : " Is it 

 conceivable that in Upper Cretaceous time, when the abundantly 

 fossiliferous Permian and Secondary deposits were in force in the 

 neighbourhood, and presumably exposed to denudation, if older 

 deposits were so, a special collection of fossils from those older 

 fossils can have been raked together, transported together, and 

 deposited together at a distance, by the promiscuous process of 

 detrital agency ? " " So long as special Palasozoic fossils only are 

 found in these beds, their Upper Cretaceous age will be open to 

 doubt." 



This argument has great force ; and evidence of a more decided 

 character will be required, before the relative age of the Conularia 

 beds, and the boulder-beds underlying them, can be regarded as 

 settled. G. J. H.

 Waagen, Ph.D., F.G.S., and Joseph Pichl. I. Productus- 

 Limestone Fossils : 5. Bryozoa — Annelida — Echinodermata. 

 With ten plates, 87—96. 



THE authors reject from the Bryozoa, and regard as Corals, such 

 forms as Stenopora, Monticulipora, and allied genera. The 

 Bryozoa described belong to the families of the Fenestellidas and 

 Thamniscids6. In the first of these families the following species 

 are recorded : Fenestella perelegans, Meek, F. jabiensis, n., Polypora 

 KonincTciana, n., P. megastoma, Kon. sp., P. gigantea, n., P. ornata, 

 n., P. sykesi, Kon. sp., P. biarmica, Keyser, P. vermicidaris, n., P. 

 transiens, n., Phjllopora jabiensis, n., P. cribellum, Kon., P. haimeana, 

 Kon., Synocladia virgulacea, Phill., Goniocladia indica, n. In the 

 family Thamniscidse are ranged Thamniscus dubius, Schlot., T. serialis, 

 n., and AcantJwcladia anreps, Schlot. In the Annelida?, Spirorbis 

 helix, King, and Serpulites indicus, n., are described. Fragmentary 

 plates and species of Eocidaris Forbesiana, Kon., are noted. The 

 following species of Crinoids are present : Gyathocrinus goUatlms, n., 

 C. virgulensis, n., C. indicus, n., C. Rattaensis, Hydriocrinus ? sp. indt., 

 Poteriocrinus, sp. indt., and PMlocrinus cometa, Kon. The descrip- 

 tions of these species are very carefully and fully drawn up, and 

 they are excellently illustrated in the accompanying plates. G.J.H.
