366 Reviews — Newell Arber's Scenery of North Devon. 



serrations on the sides extend the entire length of the lateral border 

 and are strongly and regularly developed, and that the surface 

 ornamentation in figs. 1, 2, 3, and 4 is strongly scabrous and devoid 

 of the fine anastomosing lines observed in the Sparth carapace. 



In Dr. Peach's fig. 6 the ornamentation appears somewhat less 

 rugose, and the serrations are confined to the anterior half of the 

 lateral border, as is the case in our Rochdale specimen. The two 

 lateral spines, one on either side of the rostrum (in our example) in 

 the centre of the hepatic region, seem to be replaced in the Scottish 

 specimens by an oblique line of five very small serrations. 



In the absence of appendages it will suffice to draw attention to 

 this very large and interesting carapace, which no doubt belongs to 

 the genus Anthrapalcemon ; it is doubtful, however, if it should be 

 erected into a new species. It may suffice at present to refer to it as 

 Anthrapalcemon Grossarti, var. JSoltt, var. nov. 



I should mention that in another concretion from Sparth, also 

 obtained by Mr. Fred Holt, there are parts apparently of a second 

 carapace of Anthrapalcemon, quite as large as the first already referred 

 to, but more shattered in situ. The complete carapace has its own 

 counterpart, but that has been broken in removing it to expose the 

 relievo side, and has since been joined together again.

THIS is a handsome volume well printed in large type and profusely 

 illustrated with pictorial and other views. As the author 

 remarks, it is " intended to deal solely with the nature and origin of 

 the coast scenery", and we may add that a more appropriate general 

 title would have been " The Coast Scenery of North Devon and parts 

 of "West Somerset and Cornwall ". With many parts of this coast 

 from Porlock to Clovelly and again at Bude and Boscastle geologists 

 are familiar, but no one before has made such a careful detailed study 

 of the entire coast, and in particular of the "wildest and grandest 

 cliffs" that extend between Hartland Point and Bude. 



The author in his Introduction gives a general account of the 

 geology and main topographical features. In dealing with the 

 scenery the lithological characters of the formations in the Devonian 

 and Carboniferous systems and their structural features are of prime 

 importance, but lists of fossils are recorded in the course of the work, 

 and. the aid of Mr. Henry Woods in the difficult matter of nomen- 

 clature is acknowledged in reference to the Devonian species. 

 Attention is called to the disputed age of the Morte Slates, but the 

 author "is inclined to hold, provisionally, to the older theory that
