having less depth and a greater width than in H. palliata and 

 H. Brovmii. Except in its greater size, it very closely re- 

 sembles the former species, which however wants the spiral 

 lines of long hairs in the epidermis. The operculum of this 

 species is much smoother. I adopt the name suggested by Mr. 

 Chitty. 



A variety of Helicina palliata occurs, in which the lip 

 is excessively thiclvenod both externally and internally, con- 

 tracting the aperture. It may be designated by the name of 

 LABiosA. It is a local variety.* 



A variety of Helicina maxima is remarkable for its pale 

 lemon yellow color ; it may be designated by the name of 

 ciTRiNA. The usual color of this species, under the epidermis, 

 is the same as that of H. nohilis^ (see above,) with less of 

 white. 



A variety of Helicina ampliata in the collection of Mr. 

 Chitty is of a greenish yellow color, with a broad spiral band 

 nearly covering the upper whorls, where it is dark reddish 

 brown, occupying the lower part of the middle whorls where 

 it is of a brownish slate color, and gradually becoming paler, 

 and at length on the last whorl of a red color. 



Helicina consanguinea. Shell subglobose, moderately 

 thick : dark brownish red, with the lip white ; with a some- 

 what hirsute epidermis, having the projecting points spirally 

 arranged : with the striae of growth quite distinct : apex ob- 

 tuse : spire with the outlines much curved : whorls five, mod- 

 erately convex, with a well impressed suture : aperture semi- 

 orbicuUir ; lip sinuous above, moderately thickened and sharp, 

 but well ifflectcd except at the extremities ; with the slit 

 bro.ul iiiul shallow. 



* Dr. H I'll ami remnrk?, "The H. palliata found about here [Bethany, Man 

 Ciicisicr] nevf )• ha such a ihickened lip: [the ?ame is true at Marlboro, Manchester 

 C. B. A.] : but all the specimens from Maidstone (our station on the moiintain oppo 

 site to Bethany) are of this description.
