NOTE ON A MEDUSA FROM THE TROPICAL PACIFIC. 



By R. von Lendenpeld, Ph.D. 



In 1829 Eschscholtz (System der Acalephen, p. 89, pi. XI., fig. 1), 

 described and figured a Medusa from the Tropical Pacific, under the 

 name Gorgonia rosacea. This species has been subsequently placed 

 in the genus Liriope by Gegenbauer (Versuch eines Systems der 

 Medusen, p. 257.) Later writers as L. Agassiz and E. Haeckel, 

 have adopted the view taken of this species by Gegenbauer (I.e.) 



No specimens have however, been seen by all these authors, all 

 copying the diagnosis of Eschscholtz. 



Among the Medusse collected by D. Richter of S.M. " Stosch," 

 this species is represented by two fine specimens, which were both 

 procured in the Phillippine Islands. 



Both specimens ai-e of equal size. Umbrella 5 mm. high and 

 9 mm. wide. They are consequently much larger than the 

 specimen described by Eschscholtz. 



Haeckel (System der Medusen I., p. 290), doubts the correctness 

 of the statement made by Eschscholtz that this species has no 

 " Zangenkegel," tongue cave. 



In the two specimens, which I have examined no tongue was 

 present, so that the diagnosis given by Eschscholtz appears correct 

 in this respect.
