considers that those which he examined in the Longmynd district are 

 of a coast character." Littoral accumulations have also been detected 

 in the older fossiliferous rocks of Ireland and Devonshire ; and a very 

 instructive instance, during the secondary period, is given by the au- 

 thor, and well illustrated by a map (p. 552), showing the mode of 

 occurrence of beaches (of the age of the dolomitic conglomerates),; 

 surrounding the older rocks of the Mendip hills, and the changes 

 effected in the dry land, shores, and sea bottom of a small area (proved 

 by the peculiar manner in which the organic remains are imbedded) 

 during the subsequent deposition of the lias and inferior oolite. 



With these brief remarks we conclude our notice of this valuable 

 contribution to Geological literature ; and no geologist, and certainly 

 no student of the science, can fail to derive from the perusal of the 

 work, correct and jjhilosophic views, which may render his investiga- 

 tions into the past history of the earth more interesting and practically 

 useful. 



Works in the Press, 



We learn from Mr. Ilalfs that it is his intention to publish a series 

 of specimens of British Algse. 



In order not to interfere with Mrs. Wyatt's ' Algse Danmonienses,' 

 in which she had included most of our marine species, it will be chiefly 

 confined to the freshwater species and the Diatomacese, thus forming 

 a sort of supplement to her work. The 1st fasciculus will contain 

 forty species, at ten or twelve shillings. The number of copies will 

 be limited. The following Algae are comprised in the forthcoming 

 number : — ChyJocladia rejlexa, Chantransia investiens, Chcetophora 

 fastigata, Desmo7iema Dillwi/nii, Leptothrix tinctoria, Deswidium 

 quadranffulatum, Didymoprium Borreri, Ewilaria pulchellum, &c.

 1. On the Garruline Birds, or Jays; with Descriptions 

 OF NEW species. By Charles Lucien, Erincjs Boma^

Having elevated the Garruline Crows to the rank of a full family, 

 the fifty-third of my Natural Classification of Birds, I now consider 

 the family Garnilidce, (including, besides the CrypsirhinincB, Bari- 

 tince, and the Jays, also the Hopping Magpies, notwithstanding their 

 stronger bill and closer relation to the Corcidce,) as formed of five 

 different groups (subfamilies or great genera as yon may call them, 

 according to your notions, and you admit or not subgenera). And I 

 say five, although I do not separate the Magpies from the Jays, \mt 

 consider them as Garndine, because to the three old subfamilies, 

 Baritinte, Crypsirhinince and Garrulince, I now add a fourth (Ganm- 

 laxince), for the reception of a good many birds hitherto scattered in 

 different families, whose affinity to the Jays, taken for mere analog}',
