General colour of tropliosome red.

The only information we possess regarding this species is derived from Oscar Schmidt's 

 figures, accompanied by a few explanatory words, in his ' Hand-Atlas der Vergleichenden 

 Anatomic.' These figures, however, leave ranch to be desired, while their deficiency are in no 

 respect supplied by the explanation, which, with a short note referring to the habitat of the species, 

 is the only account we have of the hydroid for which Schmidt constituted his genus AmalfhcEa. 



The medusa is figured without any marginal tentacles proceeding from the marginal bulbs, 

 a condition which we must regard as indicating an immature state of the gonosome in the speci- 

 mens from which the drawings were made. 



It is from such materials that the above description has been compiled, a description which 

 cannot be regarded as otherwise than deficient in many points which are essential for a satis- 

 factory diacrnosis.
