Polyzoa of the Adriatic. 315 



Family MyriozoidaB (part.), Sinitt. 



SCHIZOPOKELLA, Hincks. 

 Schizoporella lineolifera^ Hincks. 



When I characterized tliis species in a former part of this 

 paper I had overlooked the fact that it had already been 

 described by Busk in his ' Challenger ' Report under the 

 name of S. inarsujnfera *. I have no doubt of the identity 

 of the ' Challenger ' species with the form from the Adriatic, 

 and JMr. Busk's name must therefore supersede my own. I 

 may add that he has not noticed the stellate character of the 

 punctures on the cell- wall, which is due to the presence of a 

 few very minute denticles within the margin. The shape of 

 the orifice too as shown in the ' Challenger ' figure dilFers 

 from that which is met with in the specimens from the 

 Adriatic. In the latter the operculum is rather broad and 

 arched above, and narrows otf gradually to a blunt point. 

 The orifice should rather be described as produced and pointed 

 than as distinctly sinuated. 



Range. Marion Island, 50-75 fath., on Fucus] lat. 39° 32' 

 S., long. 171° 48' E., 150 fath., blue mud; Adriatic, on 

 Fucus. 



Beania mirahilis^ Johnston. 



Heller mentions this species as occurring once on an Alga 

 at Lesina ; but Dr. Pieper informs me that it is common on 

 AlgJB, shells, sponges, &c. 



He also states that Valkeria Vidovici, Heller (? Bower- 

 bankia pustulosa) ^ is one of the most abundant of the Polyzoa 

 of the Adriatic. 



In the present Report about forty species are enumerated 

 which are not included in Prof. Heller's work. He has re- 

 corded one hundred and five species probably distinct, making 

 a total of one hundred and forty-five for thcAdriatic. 



Of those now first recorded nine are new to science j of 

 the remainder a few, such as Chlidonia, Smittia trispinosa, 

 Schizojyofella marsupifera^ Eucratea chelata, &c., have a wide 

 distribution, or at least have occurred at isolated points remote 

 from one another. But a large proportion of them have much 

 the same range — from Southern Norway (or, in the case of 

 some, from the west and south coasts of England and Ireland)
