Geologisches Institut in Utrecht, - - "G. 13. 1897. N" 3542. Kalkstein-Hügel hinter Skroë, Neu- 

 Guinea"; another "Neu-Guinea Exped. 1903. N° 734. Lithothamnion Kalkstein. Kap Haharu 

 bei der Tami-Mündung, Neu-Guinea"; and some ones "166. 

 Macklot. Pulu Samauw". (Cp. p. 16). These sections too show 

 some fragments of the same species, which apparently is rather 

 commonly dispersed in tossil sediments in the said regions. 

 However, in the sections from Pulu Samauw the species in 

 question is very scantily represented in company with numerous 

 fragments particularly of a species, which probably is identic 

 with Lithothamnion eruèescens, although the latter not ascer- 

 tainable with certainty. Fig. 32 represents a part of the plant 

 in one of the sections from Soëk. It coincides in every respect 

 with similar sections of recent specimens. Cp. fig. 31. Among 

 the rather numerous fragments examined I have not seen any 

 one differing. Besides, in one of them occurs even a part of a conceptacle, which also in the 

 main agrees with those of sporangia in the species in question. Thus another species is added 

 to those already known living as well as fossil.
