[Mar. 20, 



the extremity of the pinna ; the terminal one small, roundish, not 

 much separated from the next. "Veins (very indistinct in the speci- 

 men) scarcely agreeing with the generic character of Pecopteris, but 

 well enough with those of P. Plukenetii, as represented by Ad. 

 Brongniart, tab. 107. fig. 3 a ; midrib faint, not reaching to the 

 apex, but breaking into very oblique and repeatedly forked side- 

 veins. 



In outline this plant strongly resembles Odontopteris Schlotheimi, 

 Ad. Br. t. 78. f. 5, except that the pinnules are smaller and more 

 numerous on each branch ; but the veins are quite different. The 

 venation approaches to that of some species of Sphenopteris ; but the 

 plant cannot well be referred to that genus, for the form and position 

 of the pinnae and pinnules are those of a Pecopteris of the section 

 Unitce. It has much resemblance to a fern from the anthracite-slates 

 of Savoy (No. 9 of my paper in Quart. Journ. Geol. Soc, vol. v. 

 p. 140), which is referred by Heer to Pecopteris Plukenetii. One of 

 McClelland's* figures of his Pecopteris qffinis (pi. 13. fig. 11 b) has 

 a resemblance in outline to this plant ; but the figure is too imperfect 

 to allow of identification. 



6. Cladophlebis. PI. X. fig. 1. 



A very small fragment of a Fern (from Kampti), not to be named 

 or identified from such very imperfect materials, perhaps belonging 

 to Pecopteris Lindleyana (of which I have seen no specimens nor 

 satisfactory description), evidently different from any other in this 

 collection. It may be referred to Brongniart's genus Cladophlebisf 

 (corresponding to Pecopteris, section Neuropteroides, of the Hist. Veg. 

 Foss.), the venation being intermediate between that of Neuropteris 

 and of Pecopteris. Pinnules about as large as those of Neuropteris 

 Loshii, and a good deal like them in shape, but more oblique ; the 

 base not cordate, but oblique or unequal-sided, and (as in Clado- 

 phlebis pteroides) only partially attached to the rachis. Midrib 

 more continuous than in Neuropteris, but less than in the typical 

 Pecopterids ; side-veins very oblique, but less arched, less crowded, 

 and more sparingly branched than in Neuropteris proper. 



I find another fragment from Kampti, which I am inclined to refer 

 to this same plant, although it is in a state which renders its deter- 

 mination doubtful. It appears to be a portion of a Fern, with the 

 leaflets reduced (probably by decay previous to fossilization) to a 

 skeleton, little else remaining of them than the veins ; whence the 

 fragment might be taken at first sight for some delicate Sphenopteris. 

 It is well known that the Sphenopteris myriophyllum, Brongn., was 

 founded on a specimen in a similar condition. 



7. T-entoptekis daujeoides, McClell. ? (Glossopteris danceoides, 

 Eoyle ?) PI. X. fig. 2. 



The specimens of this (in sandstone from Kampti) are but few and 

 very imperfect ; but they belong (as far as can be seen) to Brong- 

 niart's genus Teeniopteris, and may be the same species with the 



* Report of Geological Survey of India, 1850.
