I. — On some Coniferous Eemains eeom the Lithogeaphic Stone 



OF Solenhofen.

II. Pinites SolenJiofenensis, Dyer. 



In the Haberlein collection there is a slab containing the remains of 

 a branch, of which portions are figured in PI. V., Fig. 1. It belonged, 

 there is little reason to doubt, to a species of Pinus, in which, as in 

 the section Larix, the leaves were borne in fascicles on abortive 

 lateral branches.^ Traces of these leaves appear to exist at a and b. 

 The specimen affords, unfortunately, no more information than this ; 

 nothing of the kind, however, appears to have been recorded from 

 Solenhofen, and it has therefore appeared desirable to call attention 

 to its existence. 



III. Aihrotaxites,"^ Unger. 



A large proportion of the Solenhofen plant-remains belong to 

 types which were originally described and figured by Sternberg as 

 Algge. Their general facies, however, I think sujDports their claim to 

 be considered Coniferous, and this has been sufficiently established 

 by the fruiting specimen figured by Unger in the " Botanische 

 Zeitung" for 1849 (t. v. f. 1.), under the name of Atlirotaxites 

 lycopodioides. Schimper has given, in his "Traite de la Paleontologie 

 Vegetale," what is evidently a figure of the same specimen (t. 75, 

 f. 21), although the appearance of the cones is somewhat differently 

 interpreted. He has, in fact, founded upon the view which he has 

 taken of their structure the genus Echinostrobus (1. c, vol. ii., p. 331). 

 I have not had the opportunity of seeing the original specimen, but 

 a careful comparison of the two figures quoted above seems to me 



' The not very intelligible Schizolepis Braunii, Schenk (see Schimper, Pal. Veg., 

 ■vol. ii., p. 248) had similarly arranged foliage. 



* The name of the genus founded by Don was not Arthrotaxis, but Athrotaxis. 

 He expressly explains that the name alludes " to the crowded disposition of the leaves 

 and scales of the female spike," and that it is compounded of a.Qp6os confertus.
