extended, and more or less passive. In Fig. 3 the specimen is 

 represented in a rather characteristic state of repose often observed, 

 resting on the exumbrellar surface on the bottom of the aqua- 

 rium. Here again, the creature is in a condition of general relax- 

 ation, the manubrium extended and in position to take such prey- 

 as may come within its reach. The tentacles also are much ex- 

 tended, a condition quite common when in this pose. 





Fig. 4. 



In Fig. 4 is shown a less familiar attitude of the creature. 

 Though not especially rare, the position seems to indicate a con- 

 dition of fatigue, though the tentacles are more or less erect. A 

 comparison of the several figures, representing as closely as pos- 

 sible the living aspects of the creature, will show the general 

 relation of tentacles, velum, manubrium, shape of bell, etc., to the 

 state of activity or repose, as the case might be. 



Tentacles. 



There are four perradial tentacles, conspicuous as to size and 

 length, as shown in the several figures. In certain cases it was 

 possible to distinguish apparently, a series of four interradial 

 tentacles though they were not conspicuously differentiated as to 

 size or length. The tentacles are quite numerous, especially in 

 older specimens, and arranged in several series, younger ones 

 arising from the lower, or proximal portion of the margin. 

 While the aspect exhibited by these organs in the figures might 

 seem to indicate more or less rigidity of structure, this did not 

 appear to be the case in the living specimens. They were quite 

 flexible and highly contractile. 



In describing the tentacles of the Munich specimens Boecker 

 {op. cit.) was unable to confirm the account given by Giinther as
