let the shell alone; or, is there some absorbent that will contract 
when cool or in the process of drying that will bring it out? I have 
put my snails in boiling water, guessing at the cooking necessary for 
the different varieties, but often I cannot extract the whole animel, 
leaving a portion to discolor the spire.” 
For cleaning the exterior of water shells I find fine table salt 
about the correct thing. Rub it on with a piece of cloth or the hand. 
It has grit enough to remove lime, alge and iron stains without be- 
ing firm enough to scratch the epidermis. Often a weak solution of 
muriatic acid assists in removing iron stains and lime, and brightens 
the colors. Rinse thoroughly, and when dry rub over lightly with 
raw linseed oil.—J As. H. FERRIss. 
Notes oN soME Pupip#.—The perusal of the account of the 
Pupide in the new Catalogue suggests the following comments. 
Pupa montanella (p. 119) is not concinnula, but is a weak form of 
pentodon, found in Custer Co., Colorado. The name has never been 
sanctioned by a description, and should be dropped. P. pentodon, 
it may be remarked, was originally the type of Vertigopsis, as I had 
it in my MS.; but in Naurivus, January, 1893, Dr. Sterki takes 
curvidens as the type, and this must now hold good. Ancey’s un- 
published descriptions of his two forms of P. inger'solli are as follows : 
“War. (?) haydeni Ane. Testa preecedenti [ingerso/ii] statura 
formaque simillima, sed dentibus palatalibus 3 parallelis et sequali- 
bus, elongatis, nec. 2, discrepans. Cunningham Gulch (Ingersolli).” 
“Var. accedens, Anc., Testa typo similis, sed tuberculo parietali 
distincto prope dentem armata.” (May, 1890). Pupa sublubrica 
is hardly muscorum; a figure communicated by Mr. Ancey shows, 
besides a strong parietal tooth, one on the outer wall, and also an 
obtuse one on the columella. The figure appears to me to represent 
a form of blandi. In May, 1890, Mr. Ancey (in Jitt.) states that 
hebes was near to muscorum, and criticised Binney for putting it 
under arizonensis; thus it appears probable that gabbi may stand. 
At that time (1890) a new name was proposed in MS. by Ancey for 
arizonensis, W. G. B., but it was not published. It may be as well 
to remark here that the name Holospira remeri var. minor, published 
(Nautitus, VI, 6) by Dr. Sterki, without description, belongs to 
W. G. Binney’s var. 7, Man. Amer. Land Shells, p. 422.—T. D.
