NOTICES OF SERIALS. 5 



nucleus is then easily isolated ; it is of an irregular, oval form, quite colour- 

 less, and marked on its surface with curved striae. Individuals were fre- 

 quently seen undergoing spontaneous division, which takes place parallel to the 

 annular furrow, and in the unfurrowed hemisphere. This process appears 

 to be invariably preceded by a division of the nucleus ; and the author had 

 succeeded in isolating nuclei, presenting almost every stage of transverse fission, 

 Believing the species now described to be new, I have named it P. uberrima."

No. 144, October : (Rev. George Gordon) A list of the Mollusca, hitherto 

 found in the Province of Moray and in the Moray Firth concluded from page 

 4435. Mr. Gordon is well known to the readers of the " Zoologist" by his lists of 

 the fauna of Moray, which have, from time to time, appeared in its pages ; and the 

 present catalogue we regard as the most valuable of them all, but are sorry that the 

 Rev. George Gordon should, in his table comparing the Molluscean Fauna, of 

 Moray, with those of Northumberland and Durham, Aberdeenshire and Dublin, 

 have given the number of species frequenting the latter place so very incorrectly, as 

 actually to make it appear that the well-investigated County of Dublin, second, we 

 hold it, to none for natural history, should have no less than fifty-nine species less 

 than his favourite province of Moray. Our readers are, doubtless, aware, that Mr. 

 W. W. Walpole's list of the Dublin Mollusca, which is the one Mr. Gordon 

 refers to as his authority for the Dublin species, only gave that gentleman's own ex- 

 perience ; and numerous as any one's investigations may be, we yet hold it impossible 

 that, without aid, they could give anything like a complete catalogue : for example, 

 Mr. Walpole gives the names of 49, not 50, of the Pulmonifera as inhabiting
