pallia stelligera, Schmidt, is only a superfluous synonym 

 for Raspailia stuposa, Montagu. 



There are, as mentioned above, two species of Raspa'il'ui 

 with stellate microscleres, R. stuposa, M., and R. rir/ida, 

 M. In my former report I drew attention to Eidley and 

 Dendy's statement that the only stellate forms of micro- 

 scleres " which are certainly known to occur in the Mon- 

 axonida" are spirulse, discastra and amphiastra," and I 

 proposed that spherasters should be mentioned as a fourth 

 form of stellate microscleres in the Monaxonida, and that 

 the limits of the genus Raspailia, as given by Ridley and 

 Dendy, should be enlarged by leaving out the negative 

 character *' no microsclera," so as to reconstitute the 

 older and wider genus defined by Nardo and Schmidt. I 

 see now that Lendenfeld's definitions of the group in ques- 

 tion also want alterations. In his " Descriptive Cata- 

 logue"* the definition of the order *' CornacuHpongige," 

 which comprises also the Axinellidae, is too narrow, as it 

 gives the negative character " Microsclera, never stellate." 

 This character should be left out. Similarly in the " Mono- 

 graph!" Lendenfeld defines his sub-family " Axinellinie," 

 which includes Raspailia, as "Axinellidae without micro- 

 sclera." This definition also wants correction. 



This species which has now been found on the shores 

 of Puffin Island several times, has also been dredged on 

 the " Hyaena" expedition of May 25th, 1890, in Penihos 

 Bay, west coast of Anglesey, from a depth of about 10 

 fathoms. 

 Suberites domuncida, Nardo. 



Halichondria suherea, Montagu.
