HARDWICKE'S SCIENCE-GOSSIP.

48. Pyrulina acuminata (fig. 150), very rave at 

 Sens and St. Germain, and common at Meudon, ac- 

 cording to Morris is also found at Charing.

 Gaudryina pupoides. 



50. Gaudryina pupoides (fig. 152), also common at 

 Meudon, Sens, St. Germain, and in England, is re- 

 corded by Morris from the Gault at Folkestone, 

 English Chalk, and Charing. This completes the 

 Helicostegia group of D'Orbigny. The residue of 

 species are grouped under the order Euallostegia, 

 containing the two genera of Textularia and Sagrina.

51. Textularia trochus (fig. 153) from Meudon ; 

 since alluded to by Williamson, and found at Char- 

 ing, and in the Kentish Chalk.

 Textularia turns.

 Textularia Ba udouiniana. 



49. Gaudryina rugosa (fig. 151), common at Meu- 

 don, St. Germain, and Sons, and, as it appears from 

 Reuss in other parts of Europe, as well as at Char- 

 ing, and in English Chalk. 



52. Textularia turris (fig. 154), not uncommon at 



Sens, Meudon, St. Germain, and in England. Re- 

 corded by Reuss in Bohemia. 



53. Textularia Baudouiniana (fig. 155), rare at 

 Meudon and St. Germain, but included by Professor 

 Morris from Charing, and the Kentish Chalk. Thus 

 it will be observed that all the three species of Tex- 

 tularia are British.

54. Sagrina rugosa (fig. 15G). The only localities 

 given by D'Orbigny are St. Germain and Meudon, 

 whilst Morris adds Charing. 



This brings us to the conclusion of the species 

 figured and described by D'Orbigny in this valuable 

 Memoir. As stated at first, we do not pledge our- 

 selves to them as all good and distinct species ; that 

 is a point we will leave for discussion elsewhere 

 than in these pages. Taking them as they are, we 

 have fifty-four species, and of these no less than 

 forty-five are recorded as British ; hence five-sixths 

 of the whole are British, and only one-sixth, or nine 

 species are absent. We hope, therefore, that the 

 figures we have given will prove of service to our 

 readers, and stimulate some of them to work at these 

 organisms, for good workers are wanted, and the 

 field of operations is a wide one. Undoubtedly there 

 are discoveries still to be made. 



THE HERRING GULL. 



(Larus argentatus.) 



rpHERE is something very refreshing in the 

 ■*■ change from the inland to the littoral ; and 

 there must be few indeed who have not experienced 

 that delightful flow of spirits and quickened pulsa- 

 tion which always supervene when we leave the 

 hot and dry and dusty country, and are brought 

 gradually within sight of the far-resounding sea. 



As we are whirled along by the express, the 

 country becomes more bare and open ; the woods 

 gradually disappear ; the song-birds are left behind, 

 and gulls and peewits take their place; while 

 through the open window, in spite of dust and 

 steam, a delicious briny air comes rushing in, which 

 at once dispels all sense of fatigue, and makes us 

 long to get out, and breathe, and live in it. How 

 complete and grateful is the change which modern 

 locomotion enables [us to effect in a few hours ! 

 Yesterday, perhaps, we were walking down Bond-
