BRUSINA : PAPYROTHECA, A NEW GENUS OF GASTROPODA. 1 59 



other south Slavonic Balkan countries, which thirty years ago was 

 quite unknown to us,'- has in the space of a generation brought to light 

 a large number of remarkable new types, which call forth universal 

 admiration. 



It was not enough that one should discover a very large number 

 of singular species of the genera Unto, Melanopsis, Vwiparus, &o, 

 but one now knows to one's gratification the genera Fossarulus, 

 Neum., Prosasthenia, Neum., Dia?ia, Cless., from the Dalmatian — 

 or I might better say from the Fossarulus — Marl. Slavonia has its 

 Tylopoma, Brus., Choerina, Brus. From the immediate environs of 

 the capital of the Croatian kingdom, Zagreb (German, Agram), 

 I have described the genera Zagrabica, Brus., Boskovicia, Brus., 

 Lytostoma, Brus., Micromelania, Brus., and Baglivia, Brus. Of the 

 genus Valenciennesia, which was first known from South Russia, we 

 know to-day several forms from Croatia, Slavonia and Hungary. 

 Our most remarkable genus Orygoceras I first discovered in the 

 Levantine Fossarulus Marl of Dalmatia ; afterwards I found other 

 described species in the Pontic strata of the brother-lands Croatia 

 and Servia. Since the publication of my monograph 3 Hungarian 

 geologists have shown that Orygoceras is a well distributed genus in 

 Hungary also. 4 



Some of our genera have found universal recognition, while 

 others even at the present time are less known. The reason is 

 chiefly that these novelties are but slightly or not at all represented 

 in collections. Many of our South-slavonic genera are the more 

 interesting, since their position in the system is difficult, or not at 

 all, to be fixed. 



The number of these singular types will now be enriched by 

 a very remarkable new one. This new genus, like Orygoceras, does 

 not find its like amongst either the extinct or recent genera of 

 mollusca. 



In the first place I will endeavour to describe the form of the 

 shell in popular language. One might describe it as having the form 

 of a slipper with a pointed toe ; it recalls the former pointed shoes 

 (Rostratishoes) which in the 14th and 15th centuries were called in 

 England " Cracowes," in France " Poulaine," and in Germany 

 " Schnabelschuhe." The best description one can give is that the genus 



- Frauenfeld in 1862 described the earliest Slavonic raludina, and in the year 1865 Moritz 

 Homes described and figured the first species of Unio from Slavonia, in his great work upon the 

 " Fossilen Mollusken des Wiener-Beckens." Immediately afterwards E. Albert Bielz published, 

 unfortunately without figures, the first local fauna from Krajowa in Rumenia.
