Corallinaceae l ). Hevdrich further states that the development of the cystocarpic conceptacles 

 is quite different from that of Sphaeranthera, a genus based by him upon the type of Litho- 

 thamnion Philippii Fosl. [Lithophyllum decussatum Solms, nee Phil.). I have however shown 

 in Lithoth. Adriat. Meer 2 ) that this genus with its single species (Sph. decussata) comprehends 

 at least two different algae 3 ) and that the antheridia described by him have nothing to do 

 with the type of the species 4 ). For these reasons I keep the species in question provisionally 

 at least under the genus Lithophyllum. 



Occurrence: The two specimens above mentioned are from stat. 282. Afterwards, 

 however, I met with a small but rather well developed specimen from stat. 79 b . 



Area: South Pacific: The Tami Island on the north-eastern coast of New Guinea.

Diesen Resultaten entsprechend hat auch Schmitz darauf verzichtet, fiir die Abgrenzung der Unterfamilien der Rhodomelaceen 

 irgerid wie auf den Bau der Procarpien oder Cystocarpien zurückzugreifen. Wenn in den Gattungsdiagnosen von ihm regelmassig der 

 Bau der Cystocarpwand und der Gonimoblasten berücksichtigt wird, so gescliah das mehr der Uniformiteit wegen, zu der die Darstellungs- 

 weUe der übrigen Familien drangte, als dass er selbst besonderen Werth auf den Bau der Cystocarpien gelegt hatte". 



1) As regards the cystocarps as a genene character, I have in Rev. Syst. Surv. Melob. applied these organs in about the same 

 sense as indicated by SoLMS-LAUBACH, Corall. Monogr. p. 53 and 64. This character seems to me to be well marked and as a rule 

 easily ascertainable.
