CARPOLITHES? Sp. 41. 

 PI. XX, fig. 1. 



Sac oval formed of one layer of reticulated fibres, forming a net with irregularly 

 shaped meshes; fibres tough brown and translucent; no attachment or aperture visible. 



Length 5 mm. (of another broken specimen 8 mm.) Reuver. 



Another species of these curious nets was found by us in the Cromerian; but it 

 is slightly smaller and has much finer and more delicate reticulation than the Reuver 

 species. We did not figure it, thinking that it was probably of animal origin, though 

 we were unable to discover to what animal it could belong. We now figure one of the 

 Reuverian specimens, though we are still quite uncertain as to its position. 



CARPOLITHES Sp. 42. 

 PI. XX, figs. 2, 3. 



Globose*urceolate with narrow erect constricted band round the wide aperture; 

 walls thick, finely irregularly cellular. 



Length 1.6 mm., breadth 2.9 mm. Brunssum. 



No attachment can be traced on these specimens, and we are uncertain which 

 way up they should be placed. We cannot suggest to what order they belong. They 

 may be galls. 



CARPOLITHES Sp. 43. 

 PI. XX, figs. 4 a, b. 



Rachis flattened broad woody finely striate, showing impression of a broadly 

 ovate sessile fruit. 



Length (of fragment) 10 mm., breadth 6 mm. Brunssum. 



We can only suggest that this is part of the rachis of a palm, perhaps of the same 

 palm as that of which the fruit is figured on Pi. XIX, figs. 19—21. But the fruits have 

 only been found at Reuver and Swalmen, and this fragment of rachis comes from 

 Brunssum. For a description of these fruits see p. 71. 



CARPOLITHES Sp. 44. 

 PL XX, figs. 5, 6. 



Bracts woody broadly triangular, with a strong midrib prolonged into a narrow 

 ventrally channelled beak; ventral surface concave smooth; dorsal surface with con* 

 verging veins and fine striae. 



Length 4.0 mm., breadth 3.5 mm. Swalmen. 



This may be the fruiting bract of the palm described on p. 71, for the venation 

 suggests a monocotyledonous plant.
