IfOETH-ITALIAl^ PEYOZOA. 11 



are yicarious eared vibracular cells. The only species is V. tra- 

 pezoidea (Reuss).

The most important points have been dealt with when describing 

 the genus. 



As a rule, the zoarium is discoid or conical, but from some speci- 

 mens it would seem to sometimes grow in larger flat pieces. Eeuss, 

 in his first description, says " incrusting ;" but in his second he 

 figures and describes it as free. One specimen from Brendola is 

 incrusting, but all the others are free. 



Selenaria mioccenica, Seguenza, may be this or Onycliocella angu- 

 losa ; also Flustrellaria Tie.vagona, d'Orb., from the Senonian, seems 

 very closely allied ; but in the absence of vibracula or avicularia it 

 is in both cases impossible to say whether they are identical.

From Brendola there is a fragment of M. concatenata, Ess., 

 either in a single free layer or with two layers back to back ; and, 

 as pointed out by Koschinsky, the zooecia are the same as those 

 of 3£, macrostoma, both in shape and size. There are also some 

 fragments with squarer zooecia, which should perhaps be called 

 M. Savartii, Aud.
