On the Relation op Bucephalus to the Cockle. 



By W. Fell Woods, Esq. 



{Read April 23rd, 1875.) 



It will be in the recollection of the Club that when Dr. Moore 

 read his paper on the 23rd October opportunity could not be found 

 for its discussion. In referring to it now I shall not touch upon 

 the Mussel, of which I really know nothing. The Oyster has been 

 long studied by me, and Dr. Moore will remember that T read a 

 paper " On the Reproductive and Larval States of the Oyster" at 

 our local Society at Forest Hill, in 1872. But I do not propose 

 saying anything to-night concerning either the Oyster, or Dr. 

 Moore's remarks thereon, save that I am glad to find he now 

 supports many of my observations, though I do not think that he 

 carries his evidence of its hermaphrodism, or, more strictly speak- 

 ing, of its self-fertilising power, so far as I have done. Of his 

 drawings, [I think Figures 5 A and B (Ostrea edulis) are not 

 altogether happy illustrations of the stages they are supposed to 

 represent. 



1 turn now to " the Relation of the Bucephalus to the Cockle ;" 

 and I ought, perhaps, at once to state that, in reference to the 

 views which may be expressed, Dr. Moore and myself have not 

 acted in concert, but with complete independence. When, how- 

 ever, both had offered papers on some bi'anch of the subject, he 

 suggested that, as I had proposed treating it in reference to the 

 Cockle, he should deal with the Mussel. 



As Dr. Moore's drawings (Cardium edule) in the last number 

 of the " Quekett Journal " (No. 28) sufficiently resemble and 

 confirm my own, and the April No. (76) of the "Monthly Micro- 

 scopical Journal " contains copies of some of the drawings of B. 

 Haimeanus by M. Lacaze-Duthiers, I have thought it needful to 

 trouble you only with such rough outlines of my own as were 

 absolutely needful by way of supplement.
