bearing Upper Gondwana beds, the lateritic formations and the alluvial 
valleys of the Palar and Nagari rivers. 
The researches of the author on the Geology of the Eastern Coast, 
those of Mr. King in the southern parts of the Nizam’s territory, and 
of Messrs. Blanford and King in the Godaveri valley, and their im- 
portant and practical bearings, are fully noticed. Altogether, this 
clear and concise summary of this portion of the Indian geological 
survey is extremely useful, to which is appended a table of the several

Tur Sponaces, RapDIOLARIANS, AND FoRAMINIFERA FROM THE LOWER 
Lias Strata oF SCHAFBERG NEAR SaLzBurG (AuSsTRIAN TyRoL). 
By Dr. E. Duntxowsx1. 4to., pp. 84, with 6 Plates. 
HIS memoir contains the results of a careful investigation of the 
minute organisms met with in certain beds of dark, siliceous, 
compact limestone of Lower Lias age, which were discovered by 
Prof. Zittel. Some portions of this limestone, on treatment with 
acid, proved to be mainly composed of fragmentary sponge spicules 
(with a few other siliceous organisms), mingled together in myriads, 
so that the deposits might fairly be termed sponge beds. The author 
has described and figured the various: forms of spicules which he has 
been enabled to separate from the heterogeneous mass, and finds 
representatives of each of the four orders of fossil siliceous sponges. 
The Monactinellidg are represented by numerous spicules, character- 
istic of the genera Opetionella, Reniera or Suberites, Scolioraphis and 
Esperia. To the Tetractinellide belong various spicules of the 
Pachastrella type, as well as examples of Stelletta, Tisiphoma and 
Geodia. The author failed to recognize more than two dubious 
spicules of Lithistid sponges, but we think it very probable that 
some of the smaller trifid spicules with horizontally expanded head 
rays, delineated on Taf. 2, belong rather’ to the dermal layer of 
Lithistid sponges, than to the Tetractinellid genus Stelletia. Spicules 
of the Hexactinellidg are very abundant, and belong to the Lyssakine 
genera Stauractinella and Hyalostelia, as well as to the Dictyonine 
Tremadictyon, and Craticularia. 
The Radiolarians are brought under ten genera with eighteen new 
species; they are mostly included in Haeckel’s families of the 
Spherida and Discida. These minute organisms are fairly well pre- 
served, though oftentimes infilled with the siliceous matrix. The 
majority of the forms possess a porous sponge-like test ; but a few 
exhibit a regular lattice-like shell. 
The Foraminifera are only in the condition of siliceous casts, and 
mostly belong to the Lagenide family. 
The importance of this memoir rests on the recognition of an
