ischen Republik (Pal&ontographica, Lief, iii, p. 22). 

 Refers generally to the fossil Sponges met with, and figures a small form, 

 subsequently named by Zittel Protacliilleum Kayseri.

andern Thierreste aus der jungsten Kreide Westfalens (Palceonto- 

 graphica, Bd. xxii, p. 68, PI. ii, fig. 10). 

 Describes as a new genus of Sponges, Glenodictyum, a fibrous body growing 

 in the form of a hexagonal mesh-work. The minute structure cannot be 

 recognised and the character of the fossil is very problematical. 



136. 1876 Sollas, W. J. On Eubrochus clausus, a vitreo-hexactinellid Sponge 



from the Cambridge Coprolite Bed (Geol. Mag., pp. 398 — 403, 

 PI. XIV). 

 Describes the form and compares its external structure with that of the 

 existing genus Farrea, but the fossil Sponge is stated to possess an interior 

 skeleton as well as an outer membrane.

Organisation fossiler Spongien (Abh. der k. bayer. AJcad. der Wiss., 



II CI., xii Bd., iii Ab., pp. 1— SO, Pis. I— VII). 

 An elaborate monograph on the general structure, the canal-system, and 

 skeletal mesh of the Sponges of this genus. The nodes of the spicules are 

 compared with those of the living genus Myliusia. The body of the Sponge 

 is shown to consist of thin walls of spicular tissue disposed in radiating folds, 

 which are enclosed in a cribriform dermal layer. Numerous detached spicules 

 in the interior of these Sponges are erroneously regarded as belonging to their 

 skeletal structures, but Zittell subsequently pointed out that their presence 

 was accidental.

Fossils. 

 From the Upper Girvan series Ischadites Koenigii is recorded, and Hyalo- 

 nema parallelum and Acanthospongia Smithii from the Carboniferous of 

 Ayrshire.

 The forms described by Rutot as Sponges are regarded by Carter as the 

 tubes of a new type of Annelids. The siliceous spicules associated with them
