Palaeontology. — De Heer Molbngraaff biedt eene mededeeling 

 aan van den Heer Clemend Reid F. R. S. and Mrs Eleanor 

 M. Reid B. Sc: "On Dulichium vespiforme sp. nov. f v om the 

 brick-earth of Tegelen" . 



(Mede aangeboden door den Heer F. A. F. G. Went). 



In our paper on the Fossil Flora of Tegelen published in 1907 l ) 

 we figured a fruit provisionally referred to Rhynchospora, though it 

 did not possess the articulate beak of that genus. All the specimens 

 then available were so much distorted and injured by germination 

 that it was difficult to determine what the charaeter of the perfect 

 fruit would be. In addition to this, the most perfect specimen appeared 

 to possess a quadrate base and 8 setae, characters unknown in 

 Dulichium, to which genus the fruit was in other respects comparable. 



Since the publication of our paper we have obtained more material, 

 thanks to the kindness of Dr. Lorié and Baron L. Greinde. This 

 new material and a closer examination of the specimens before col- 

 lected, enables us now to describe the fruit as a new species belonging 

 te Dulichium, a genus now confined to America, though already 

 recorded by Dr. N. Hartz as occurring in an interglacial peat-moss 

 in Denmark 2 ). Dr. Hartz's specimens are referred, we think correctly, 

 to the only living species, Dulichium spathaceum; our fruits are very 

 different. 



Fructus dimidio brevior eo D. spathacei tarnen latior, long. (rostro 

 incluso) circiter 3 — 5 mm.; setae 7 vel 8 (forsitan 9), longitudinaliter 

 complanatae, canaliculatae, striatae; nux ovata subito in stipitem 

 coarctata, in rostrum longum gracile attenuata, paulo triangularis 

 vel plano-convexa, praesertim rostrum versus; superficies foveolata, 

 multangula, ea D. spathacei crassior; long. (rostro excluso) 2.0 — 2.5 

 mm., lat. 1 mm. 



Figs. 1 — 8, photographed on the same scale, show the diiferences 

 between the recent and fossil forms. In the living species the nut is 

 oblong, not ovate, and is much narrower in proportion to its length. 

 The long stalked nut with oblique attachment, inarticulate style, setae 

 more than 6 with recurved hooks, are generic characters common 

 to the two species. In section the nut of D. vespiforme is somewhat 

 triangular near the base, becomes plano-convex in the middle, but
