Dr. Gould described the following new species of Helix, 

 from the Shells of the Exploring Expedition. 



Helix labiosa. Testa depresso-conica, subtus convexa, arcle 

 umbilicuta, luteo-cornea, pilis sericeis quincuncialiter disposilis 

 undique villosa : spira anfr. 6 convexis, ultimo immodice cres- 

 cente et pone labrum valde conlracto : apertura angusta, lunata ; 

 labro albo, late revoluto ; fauce livida. Lat. -^'y, alt. -^^ poll. 

 Hab. Astoria, Oregon. 



Closely allied to H. paUiata, but is smaller, lacks the tooth on 

 the columella, which, with the greater convexity beneath, and 

 the rapid enlargement of the last whorl near the aperture, are 

 sufficiently distinctive characters. It seems to be nearly like H. 

 Columbiana^ Lea, a shell with which I am not acquainted. 



Helix loricata. Testa parva, depressa, flavo-viridis, arete 

 umbilicata, squamulis crescenliformibus undique loricata, subtus 

 convexa : spira anfr. 5^ convexiusculis, arete volutis, ultimo su- 

 perne ad peripheriam subangulato : apertura contracta, lunata, 

 trilobata, dente laterali, dente basali, et dente columellari lamelli- 

 formi ringens ; peristomate albo, reflexo, callo copioso conjuncto. 

 Lat. \^ alt. ^^ poll. Hab. California. 



Form much like H. inflecta^ but smaller, and teeth less devel- 

 oped. Its peculiar surface, resembling a scaly coat of mail, is 

 highly characteristic. 



Helix devia. Testa orbiculato-depressa, oblique striata, 

 dilute viridi-cornea, umbilico modico canaliculato perforata : spira 

 anfr. 6 convexis, ultimo ad peripheriam rotundato : apertura 

 transversa, oblique lunata, ad anfractum penultimum unidentata, 

 dente trigono ; labro albo, late reflexo, ad basim horizontali, um- 

 bilicum aliquanto ambiente. Lat. |, alt. /^ poll. Hab. Ore- 

 gon. 



Much like H. pedesii'is., but more solid, and lacks the pecu- 

 liar wrinkling of the epidermis. The lip is more broadly re- 

 flected, and the aperture toothed. Placed by the side of the 

 southern variety of H. palliafa, somewhat blanched, it would 

 hardly be distinguished except by the umbilicus. 



Helix gulosa. Testa globulosa, crassa, rudis, sub-perfo- 

 rata, obsolete carinata, pallide castanea, colore saturatiori nu- 

 bilata, et interdum fasciata : spira anfr. 6 rotundatis, striatis ;
