Tertiary Fossils of Canada, Sfc, 



191 



All of these except one are well known living species, and all 

 except Textularia variahiUs have been found in the Gulf of St. 

 Lawrence. This last statement however could not have been 

 made but for specimens obtained from clay taken up by the 

 sounding lead off the coast of Anticosti, from depths varying 

 from 144 to 313 fathoms, and for which also I am indebted to 

 Capt. Orlebar. In these soundings there also occur Globigerina 

 hulloidesa species world-wide in its distribution, and Nodosaria 

 pyrula, neither of which have as yet been found in the tertiary 

 beds of Canada. AVith these recent shells there is a Cythere like 

 C. angulata of the British seas, and numerous spicules of spon- 

 ges; there are also immense numbers of the round perforated 

 silicious shields of Cosa'/iocZisci apparently the C. lineatus &T\d C. 

 radiatus of Ehrenberg. It is a remarkable and at present unac- 

 countable fact that while in the pleistocene beds there is a 

 great abundance of foraminifera, sporge spicules, and valves of 

 cythere, imbedded in calcareous clays like those of the deep sound- 

 ings of the Gulf, the Coscinodisci and other diatoms are absent 

 or at least have not been recognised.

Truncaiulina lohata. The last species in the list is a little 

 parasitic foraminiferous shell adhermg to shells, stones, and 

 zoophytes. It abounds in Mr. Bell's and Mr. Richardson's recent 

 collections from Gaspe, and since I observed it in Capt. Orlebar's 

 collection, I have found it also at Montreal. It is the Nautilus 

 stellaris of Fabricius. 



The Nonionina which I name N, Labradorica^ and which is 

 found both recent and fossil, is a very beautiful species. It is 

 pel fectly equilateral, smooth and remarkably white and lustrous^ 

 It is most readily characterised by the great expansion of the last 

 chamber, which spreads laterally and extends in two lobes on
