 ^ Halecium Olcen, 1815. The short, simple, 

 symmetrical calycles of the sterile hydra^, which are 

 too small to allow tlic animal to retreat in them, 

 and the one-sided fertile calycles, seem to indicate 

 a distinct family.

 * Halecium Beanii Johnst., and H. muricatum 

 Johnst., seem to me to be generically distinct from 

 H. halecinum, but I have not the means of ascer- 

 taining their true characters. If they constitute 

 distinct genera, the characters now assigned to the 

 genus will require modifications. VanBeneden has 

 figured the animal of H. halecinum. Bull. Ace. 

 Belg., 1847, Vol. XIV. p. 462. The fertile hydra 

 is double-headed and tentaculated.
