MULTIPLE CHROMATOPHORES IN ANTHOCEROS. —In 1897 the writer 
collected in Jamaica a sterile fragment of an Anthoceros , in which the superficial cells 
showed two chromatophores instead of the single one characteristic of the Anthocerotes. 
Since that time, repeated search has been made for similar species, but hitherto 
without success. 
In Ceylon various species of Ajithoceros were collected, but none showed any 
deviation from the ordinary type. 
While in Buitenzorg, an Anthoceros was found in the Tjiapus Gorge at the base 
of Mount Salak, which showed frequent instances of double chromatophores in the 
superficial cells. An examination of the inner tissue of the thallus revealed the 
presence of multiple chromatophores in all the cells. There were not infrequently as 
many as eight in a cell. 
The same species (or a closely related one) was afterwards collected at a number 
of places near Tjibodas where it was not at all uncommon. 
This species belongs to the section of the genus with spiral elaters and no 
stomata in the sporophyte. In both respects it comes nearer Dendroceros than 
Anthoceros , although the thallus is that of a typical Anthoceros. 
All of the Javanese specimens showed also a solitary antheridium, and chlorophyll 
in the ripe spores, also suggestive of Dendroceros. 
The pyrenoid, usually so conspicuous in the chromatophores of the Anthocerotes, 
seems to be quite absent, and in this respect, as well as in the increased number of the 
chromatophores, there is a close approach to the chromatophores of the other 
Archegoniates. 
The plants usually grew on rotten logs, but were also met with on earth and 
damp rocks. 
If it should prove that all of the species belonging to the section of Anthoceros 
with spiral elaters and no stomata have multiple chromatophores, it will probably be 
found necessary to separate them as a new genus, intermediate to some extent between 
Anthoceros and Dendroceros,
