INVEKTEBEATA. 309 



in the main confirms the conclusions arrived at by Mr. Billings with 

 regard to the structure of the skeleton. He affirms, however, that the 

 inner integument is not foraminated in the above species ; and he lays 

 great stress upon the fact that the plates of the outer and inner inte- 

 guments, but especially of the former, are perforated by canals, which 

 radiate from a central point, and run parallel with the flat surfaces of 

 the plates. The pillars which connect the two integuments are hollow ; 

 and their central canals communicate with the tubes just spoken of, 

 whilst these latter appear to open on the edges of the plates of the 

 inner integument into the central cavity of the fossil. The true form 

 of the fossil in Receptacalites Neptivni appears to have been cup-shaped. 

 Upon the whole Dr. Giimbel concludes that there is no affinity between 

 Meceptaculites and the Sponges, but that the genus may be referred to 

 the Foraminifera, though upon grounds difl'erent from those advanced by 

 Mr. Salter. He also considers Ischadites and Tetragonis as identical 

 with Hecejptaculites. H. A. N.

This paper is supplementary to that in Geol. Mag. dec. ii. vol. i. 

 p. 433, and contains descriptions of two new species, Leda clava and 

 Ditrvpa dentalinum. The name of Crassinella is proposed in substitu- 

 tion for that of Gouldia, preoccupied for a genus of birds. H. A. N^.

 This division of the Hungarian Tertiaries in the district between the 

 Bakony and Matra Hills consists at the top of clays and below of marls; 

 in the latter occur Nummidites, Orhitoides^ Operculma., Heterostegina., 

 which are mostly absent in the former. The present instalment relates 

 to the Foraminifera only ; other classes of fossils will be treated of sub- 

 sequently. The following new species are now described : — Gaudryina 

 textilarioides^ G. irregularis, Clavulina cylindrical Cornuspira oligogyra, 

 Triloculina Porvaensis, Nodosaria coarctata, N. JBudensis, Dentaliua 

 sid)laxa. D. intermedia, D. Budensis, D. Gtiembeli, D. semilcevis, D. setosa^ 

 Lingulina glabra., Frondicidaria superha, FlahelUna striata., F. Budensis^ 

 Pleurostomella acuta, Marginulina subbullata, M. recta, M. indifferens, 

 M. Budensis, M. pauciliculata, M. splendens, Cristellaria Schivageri, C.
