 boniferous Tolyzoa. Ami. Nat, Hist. ser. 4, vol. xv. pp. 43-45, 

 pi. iv. B. figs. 1-4. 



Proposes the provisional name of Hyphasmopora for certain small 

 Carboniferous Polyzoa, which apparently cannot be referred to any 

 previously described group. The genus is defined as follows : — " Poly- 

 zoarium dendroid (?), calcareous, composed of small cylindrical stems, 

 often bifurcating. Cell-depressions arranged in linear longitudinal 

 series, more or less separated from one another by a cancellated net- 

 work or reticulation, forming the interstitial surface, and predominating 

 at one part of the polyzoarium more than at others, presenting a longi- 

 tudinal zone devoid, or nearly so, of cell- depressions. The interstitial 

 network consists of a series of irregularly formed pores." The only 

 known species is named Hyphasmopora BusJcii, and is quoted from 

 various localities in the L. Carboniferous rocks of Scotland. H. A. N.

Describes a new provisional species under the name of M. McCoyana. 

 The presence of Spiroporina vertehralis on the same piece of matrix is 

 pointed out. II. E., Jun

Describes 37 species, chiefly Ammonites, together with Aptychus, 

 J^ele'/miites^aiid Terebratula janitor. The following are new — Belemnites 

 Voir onensis, Ammonites Lucingce, A. Pralairei, A. Navillei, A. homi- 

 nalis, A. Lemani. The fossils are all from one locality, divided into 

 two zones — the lower equivalent to the transversarius-zone (Oxfordian), 

 and the upper to the tenuilobatus-zone (Kimmeridgian) ; many species, 

 however, are common to both. A comparison with the same zones in 

 other localities of the Western Alps is added. E. B. T.

Contains a description of a sarcodic animal (Dendrina enroj)cea) 



found burrowing in the shells of Mollusca, which the author believes 



to be the recent representative of the Dendrince noticed in Belemnitella 



and the shells of other Secondary Mollusks. Deoidrina diff'ers from 



Cliona in some important particulars : it is much smaller, has only a 



single large perforation ; the burrows are not divided into separate 



chambers ; very minute tubes pass from the burrows to the surface of
