 " The bell is 1" broad, h" high, divided into eight rays; 

 pedicel nearly cylindric, or somewhat rounded four-cor- 

 riered, h" long, ^" thick, ends in a flat disc, in the middle 

 of which is a small round opening," (" basal pore projects 

 into the gelatinous substance as a blind sac ") ; " four 

 brown red thick stripes in the stem, w^hich prove them- 

 selves to be muscles .by the movements of the animal," 

 [Keferstein shows that these are the camerae, and tliat the 

 true muscles are alternate with them ; the camerae situated 

 as in H. salpinx, and similar in shape and proportions] : 

 "tentacles 40-60, short, thin," ("25-27 tentacles, the 

 knob strictly globular ") ; * " marginal bodies small, re- 

 verted, oblong cylindric, open at both ends, from the outer

 and specimens sent to me by the latter, in two rows in 

 each band] " fastened to a very thin filiform tube," [this 



♦ Keferstein's specimens were evidently young, as the number of tentacles 

 shows. The specimens which he sent mo arc all young.
