A Cutleria is not a synthesis of two, but of three genera—Cutleria 
proper, Aglaozonia, and the ‘colonnette’ of a genus unknown 
. Sauvageau compares this a ionnette” with othe genera of 
Pheosporea, and considers that it most nearly approaches Myrio- 
trichia and Litosiphon. Finally, he gives a table of affinities of the 
different parts of a Cutleria, ranging from Ectocarpus to Laminaria, 
which opens up wide fields for speculation. 
The second part of the ‘ Beitriige z. Kenntniss der Meeresalgen,” 
by Dr. Kuckuck, published in Wissenschaftliche . Meeresuntersuch- 
ungen, Vol. iil., has been asa separately by t e ‘* Biologische 
Anstalt mae Helgoland.’’ It contains Nos. 5 to 9 kee and is, 
like the first part issued in 1807, Zag dao illustrated. In 
No. 5, which is entitled ‘‘ Kin r Asperococcus mit beiderlei 
Sporangien,” Dr. Kuckuck debixtbos and figures in various stages a 
small sates of Asperococcus found in the Adriatic, which he ‘calls 
rhizoids to the substratum. Its height is about 8-4 mm., and it is 
solid throughout. Both kinds of sporangia arise as outgrowths 
from the cortical cells, intermingled with hairs and, in the case of the 
unilocular Fp pe with paraphyses (called here ‘stacheln”). The 
hairs are figured sometimes with, sometimes without, the basal 
sheath, which has ae described for this and a few o ther genera
