Aytoun lias evidently devoted himself lovingly, faithfully, conscien. 



tiously ; and the result appears in these volumes, which cannot fail 



to be welcome to all who caa appreciate true poetry, warbled in the 



wild wood notes and rude epics, of those simple and unlettered 



elder sons of song : the Scottish Makars.

ATRTPA HEMIPLICATA. 



Mr. Billings of the Geological Survey lias discovered, by grinding off the beaks 

 of several specimens, that Hall's Atrypa hemiplicata of the Trenton Limestone, is 

 a true Pentamerus. Mr, Billings requests us to state also, that his P. reversus 

 from the Middle siluriau Series, is simply a large variety of the first named species 

 [P. hemipiicatiis']. 



AMERICAN TRIIOBITES. 



Mr. Salter has communicated to the Geological Society of London (Feb. 23, 

 1859) a brief notice of a new species of Paradoxides, P. novo-repertus (Salter;), for- 

 warded to him from Newfoundland by Mr. Bennet. It appears to be the largest 

 species of that genus yet known, the example in question being 9^ inches broad. 

 Mr. Salter has also described in the same communication a new species of Conoce- 

 PHALUs, G. antiquatus (Salter) from a specimen brought from Georgia in 1851, by 

 Dr. Feuchtwanger. These trilobites, in Mr. Salter's opinion, indicate the presence 

 of Barrande's " Zone Primordiale," (hitherto of doubtful recognition) in our 

 Western Continent. The imperfect trilobite from the Calciferous Sand Rock of 

 Canada, formerly referred by Mr. Salter to Paradoxides, he now considers to be au 

 Asaphus. 



DEVONIAN tLANTS FROM GASPE. 



Professor Dawson, Principal of McGill College, Montreal, has recently presented 

 to the Canadian Institute a series of interesting fossil plants from the devonian 

 rocks of Gaspe. The conditions of occurrence and general relations of these plants 

 are described by Professor Dawson in a paper communicated to the Geological 

 Society of London, on the 5 th of last January. The following summary of this 

 paper is quoted from the Philosophical Magazine of the ensuing month. " The 

 plant-bearing rocks in the peninsula of Gasp6 were first noticed by Sir W. E. 

 Logan in 1843. To determine the fossil plants accurately, it was necessary to 

 study them in place. With this view Dr. Dawson visited Gasp6 last summer, and 

 carefully examined the localities by the aid of the plans and sections of the Geolo- 

 gical Survey of Canada. The strata referred to have a vertical thickness of 7000
