EXPLANATION OF THE PLATES AND WOOD-CUTS. 



PLATE XIX. 



Map and Sections illustrative of Capt. Cautley's Memoir on the structure of the Sevdlik 

 Hills, and the Organic Remains found in them : p. 267. 



WOOD-CUTS 



To illustrate Prof. Sedgwick and Mr. Murchison's paper on a raised beach in Barn- 

 staple or Bideford Bay, on the north-west coast of Devonshire. 

 General view of the line of coast : p. 279. 

 Sectional view of the raised beach : p. 286. 



PLATES XX. to XXVL 



To illustrate Capt. Grant's Memoir on Cutch : p. 289. 



Plate XX. 



Map. — This map, drawn to a scale of about 11 miles to an inch, is taken principally 

 from one by Capt. A. Barnes ; corrected from other sources, and from my own 

 observations. The geological divisions marked on it do not pi'ofess to follow the 

 exact boundaries of each formation, but merely to give in a general view as cor- 

 rect an idea of them as my examination of the country enabled me to do. The 

 blank part, near the upper right-hand corner of the map, shows the portion of 

 the Runn flooded by the Loonee river during the monsoons. The section is 

 intended to give merely an idea of the different ranges of hills, as well as to show 

 the manner in which the surface of the province is occupied by each formation.

Plants from the Sandstone and Clay, with beds of coal; and shells from the Upper 

 Secondary Formation : pp. 292, 296. 



,^ „ , „ Plants described by Mr. J. Morris.^ 



Ptilophyllum. -^ 



Stem — ? Fronds pinnate ; pinna? closely approximated, linear, lanceolate, more or less 



elongate, imbricate at the base, attached obliquely; base semicircular or rounded; 



veins equal, slender, parallel. 



We have ventured to form these fossils into a distinct genus, conceiving that the 



circumstances of the oblique insertion of the pinnae and their overlapping each 



other at the base, are characters too important to admit of their being united to 



the genus Zamites, to which somewhat similar fossils have hitherto been referred; 



the Z. pectinata of the Fossil Flora belongs to this genus, and a careful revision of 



the fossil Cycadece may probably discover other species having this mode of at- 



* The plants are stated in p. 294 to consist of ferns and reeds, but when the Memoir was passed through 

 the press the specimens had not been examined by Mr. Morris.
