4. Plants from the Devonian of Ottendorf and Brattnatt in 

 Bohemia. By Dr. Dionys Stur, For.C.G.S. 



[Proc. Imp. Geol. Inst. Vienna, January 21, 1873.] 



Callipteris conferta, generally well preserved, is not uncommon in 

 the bituminous limestones of Ottendorf. It also occurs occasionally 

 in the form described by Weiss as C. prcelongata, in which the pin- 

 nules at the apex of the pinnae are elongated, and the pinnae thus 

 acquire a remarkable fan-like structure, those situated near the apex 

 of the frond forming a far more acute angle with the rhachis than 

 those nearer the base, which finally diverge nearly at right angles. 

 A piece of shale from Braunau contains a plant closely resembling 

 the figure of Xenopteris (Neuropteris) Dufresnoyi, Brong., but differ- 

 ing therefrom in the oval form of its pinnule, which appears con- 

 stricted at the base, like that of a Cyclopteris, and in its much 

 coarser veins, some of which, at least in the upper half of the pin- 

 nule, seem to anastomose as in Sagenopteris. From the Cyclopteris- 

 like pinnules which, according to Weiss, clothe the rhachis of Odon- 

 topteris obtusa, Brong., those from Braunau differ in their coarser 

 venation and in the smaller constriction of their base. The author 

 is inclined to regard the plant as a new species, analogous to Xeno- 

 pteris Dufresnoyi. [Count M.] 



5. Fossil Phyllosomes, from Solenhofen. By Prof. K". von Seebach. 



[Zeitschr. deutsch. geol. Gesellsch. Ed. xxv. Heft 2.] 



Prof. Seebach maintains that the fossil described by Miinster under 

 the name of Phalangites prisms, and referred by him to the Order 

 Phalangida among the Arachnida, is in reality a Phyllosome. The 

 animal was placed with the true spiders under the name of Palpipes 

 by J. P. Roth, who distinguished two species of the genus, P. 

 priscus and P. cursor. Quenstedt distinguished also a Pycnogonites 

 uncinatus. H. von Meyer regarded the forms in question as Crus- 

 tacea of doubtful position. 



From a careful examination of 18 fine specimens, the author is 

 convinced that the forms described under the generic names of Pha- 

 langites, Palpipes, and Pycnogonites are fossil Phyllosomes, as, indeed, 

 was indicated by Gerstacker ten years ago, in a note which seems 

 to have escaped observation. The living Phyllosomes are known to 

 be larval states of the Palinuridae, a family which includes two de- 

 scribed genera from Solenhofen, namely Palinurina and Eryon ; and 

 from the great predominance of the latter, the author is inclined to 

 regard his Phyllosomes as, for the most part, larvae of species of 

 that genus. [W. S. D.] 



6. New Istrian Fossils. By Dr. G. Stache. 



[Proc. Imp. Geol. Inst. Vienna, April 15, 1873.] 



Dr. Stache has communicated some of the results of his geological 



investigations in Istria to the Geological Institute. He describes : — 



1. A dark bituminous calcareous shale, filled with large Forami-
