Vallotiia pidchella and V. costata. — Dr. Sterki in distinguishing 

 between these two forms as known to him, amongst other differences 

 cites^ "The presence of very fine, raised revolving lines on the nucleus 

 or the 1 1/2 embryonal whorls [of V. costata\ while those of V. pulchella 

 are smooth." This feature alone is a very important one and could it 

 be established would be quite sufficient to prove the distinctness of 

 the two forms. A very careful examination under the microscope ot 

 an extended series drawn from various quarters, in my own collection, 

 failed to yield a single specimen showing these nuclear striae hcTwever 

 strong the costse might be, while the gradation between the costate 

 and non-costate forms was traceable, and both forms are found side 

 by side in some localities. Under these circumstances and from a 

 consideration of the rest of Dr. Sterki's description and of his figures I 

 conclude that there is a costate form of Vallonia in America distinct 

 from the costate variety of V. pulchella present in Britain, and I 

 recommend that, until it can be demonstrated more conclusively than 

 has at present been done that there are two British species, the 

 costate form be cla^^d as a variety of the typical V. pulchella. 



Helix aspersa. — The examples of this species in the Linnean 

 collection occupy a tray labelled H. grisea. The figures-referred to by 

 Linne, however, and his locality, suggest a species near H. pomatia, 

 and I agree with Hanley- that the determination is too uncertain and 

 the name must be dropped. Possibly the present occupants of the 

 tray are some of Sir J. E. Smith's additions. 



Tachea having been proposed for a genus of Aves by Fleming in 

 1822 ("Phil. Zool") it is necessary to adopt Cepcea of Held (/m, 1837, 

 col. 910). 



Bulimhia was Ehrenberg's spelling of the name for his new genus 

 and since there is nothing wrong about it, it is hard to understand 

 why or how it got converted into Buliiniuus. The name is pre- 

 occupied, however, for Foraminifera'^ and Leach's name E^ia must be 

 used with the corresponding family name Enidse. 



Pupa, if the laws of priority are to be followed, must unfortunately 

 be given up. The name was first used in 1797 by Humphrey ("Mus. 

 Calon.," p. 64) for a series of species, some from the West Indies, 

 which cannot now be recognized. It was next employed by Bolten in 

 1798 ("Mus. Bolt.," p. Tio) for Valuta solidula (now the type of 

 Solidula) and V. flaminea (now referred to Acteou). Lamarck, May 

 or June, 1801 ("Syst. Anim. s. Vert.," p. 88) introduced the name for 

 P. uva (which is a synonym for Cerioti uva of Bolten) and in July, 

 1801, Draparnaud ("Tabl. Moll.," pp. 32 and 56, probably intending to
