It is evident that the region of the Philippines* is very rich in scypho- 
meduse, for off the far better-known Atlantic coast of the United 
States there are but 25 species of seyphomeduse and only 4 of these are 
Rhizostome, while among the 38 species taken by the Albatross, 
and by Light, in the region of the Philippines, 22 are Rhizostome. 
Among these 38 species 15 were new to science. 
The discovery of a Cotylorhiza allied to the form known from the 
Mediterranean is interesting, but the most curious Philippine genus is 
Lobonema, wherein the marginal lobes of the bell are greatly extended 
and superficially resemble tentacles tapering gradually throughout 
their length to pointed tips. They are, however, not capable of con- 
traction and their function is problematical. 
It appears that in Borneo and the Celebes, some of the Scypho- 
medusz are specifically distinct from their close relatives found in the 
Philippines, the difference probably being due to geographical isolation. 
As the Albatross collected only conspicuous forms of scyphomeduse, 
and as several species are represented by only one or a very few speci- 
mens, it seems probable that further studies in the region would be 
fruitful in discoveries, and in any event the forms should be studied 
in life, for much that is of interest is lost through the effects of preserva- 
tive fluids. 
By contrast with the richness of the Philippines, the poverty of the 
Great Barrier Reef of Queensland and the southern coast of Papua, 
east of Torres Straits is remarkable, for only six species of seyphome- 
dus and ten of hydromeduse were found by the expedition of the 
Carnegie Institution of Washington to Torres Straits, as follows: 
SCYPHOMEDUS#. 
Aurellia labiata Chamisso and Eysenhardt; 
Thursday Island, Torres Straits. 
Cassiopea andromeda var. baduensis, nov. 
var.; Badu Island, Torres Straits. 
Catostylus mosaicus L. Agassiz; cobalt blue, 
from the mouth of the Brisbane River, 
Queensland. 
Linuche unguiculata forma aquila Haeckel; 
from Thursday Island, Torres Straits, 
November 23, 1913. 
Mastigias papua L. Agassiz; Port Moresby 
Harbor, Papua, November 12-20, 1913. 
Nausithoé punctata KGlliker; from Torres 
Straits and the southeast coast of Papua. 
HYDROMEDUS FROM THE 
MURRAY ISLANDS. 
/Equorea macrodactyla (Brandt). 
Aglaura hemistoma Péron and Lesueur. 
Cytzis atlantica (Steenstrup). 
Eutima australis, nov. sp. 
Laodicea fijiana A. Agassiz and Mayer. 
Liriope rosacea Gegenbaur. 
Phialidium pacificum (Maas). 
Rhopalonema velatum Gegenbaur. 
Solmundella mediterranea (Miiller). 
Stomotoca turrida (Mayer). 
During September and October 1913, we studied for 5 weeks upon 
Maér Island, about 70 miles south of Papua; using a naphtha launch 
and towing with surface nets under the best conditions, but the results 
are remarkable only for their poverty. 
*§. F. Licgut, 1914, Philippine Journal of Science, vol. 9, No. 3, describes 7 species from the 
Philippines other than those obtained by the Albatross. Mr. Light’s additional species are 
Dactylometra quinquecirrha, Cassiopea polypoides, Cassiopea medusa sp. nov., Acromitus macu- 
losus gen. et sp. nov., Lobonema mayeri nov. sp., Lobonemoides gracilis gen. et sp. nov., and 
Rhopilema visayana nov. sp.
