60 THE NAUTILUS. 



Vallonia pulchella Mull. "In a yard at base of rose bushes" 

 not before reported from California. Possibly imported with the 

 roses. 



Pompholyx effusa Lea. 



Planorbis lumens Cpr. 



Planorbis parvus Say. 



Llmnce.a adelincc Tryon. 



Ancylas oregonensis Clessin. 



Lanx patell.oidea Lea. This species, originally described as an 

 Ancylns, is the only species of Ancylinse with variegated, opaque 

 coloring. It looks a good deal like Acmcea testudinalis var. alveus 

 Conr. Notes on the anatomy with illustrations, will be given later. 



NOTE ON THE SUBGENUS EucosMiA CPR. Eucosmia, comprises 

 a number of minute shells like Phasianella in smoothness and the 

 stony operculum, but differing in being depressed with very short 

 spire. Carpenter described four species from Cape St. Lucas and 

 Mazatlan, variegata with var. substriata, pitndata, cyclostoma and 

 striatula. Dull has lately described another lurida, from British 

 Columbia ; perhaps Turbo phasianella C. B. Adams, from Panama 

 belongs here, and minima Phil, from Peru pretty certainly does. 

 In the Gulf of Mexico we have E. brevis Orb. No species from 

 other than American waters are known to belong here. It has 

 hitherto escaped notice, I believe, that the name Eucosmia is pre- 

 occupied in zoology for a group of moths established by Stephens 

 in 1829. The Molluscan Eucosmia may therefore be called Eulithi- 

 dium to distinguish it from the group of Lepidoptera. 



PUBLICATIONS RECEIVED. 



NOTES SUR LA FAUNA DU HAUT TONQUIN, par H. Fischer (Bull. 

 Sci. France et Belg. xxviii, 1898). The present paper relates to 

 shells collected by Dr. A. Billet. Interesting new species of Cama'.iui, 

 Plectopylis, Clausilia etc., are described and figured.

ARMATURE OF HELICOID LAND SHELLS, by G. K. Gude (Science- 

 Gossip iv, No. 44, 45). We have already alluded to this very 

 important series of papers. The present installments continue the 

 genus Plectopylis, the following being new: P. leucochilus, P. 

 perrieroe, P. blanda.
