NOTES ON THE NOMENCLATURE OF PUPILLID.E. 



BY U. A. 1'ILSKKV. 



The receipt of an article from Professor Cockerell upon tliis sub- 

 ject, published in this number, causes me to insert here Mime notes 

 which had been prepared for a forthcoming paper upon the snails of 

 Arizona and New Mexico. The status of the name Pupa was dis- 

 cussed by Mr. B. B. Woodward (Journ. of Conch., Oct., 1903,3.58). 

 who did good work towards clearing the ground. Dall in this jour- 

 nal for February, '04, also went over the nomenclature correcting 

 some errors, but complicating the question by a few new ones. His 

 statement that " Risso's first species [of Jaminia] is Vertigo minu- 

 tissima Hartmann, which should properly have been placed in Sura- 

 phia" is not borne out by an examination of Risso's work, wherein 

 the species stand thus:

All of Risso's species of Jaminia that are recognizable belong to 

 the subsequent groups Ena 1831, Pupilla 1831, Abida 1831, Encore 

 1837, and Lauria 1840. 



Now P. muscorum under the name maryinata was second of the two 

 species for which the name Pupilla was proposed in 1831 in Turton's 

 Manual, the other being P. umbilicata. The latter was removed in 

 1840 to Lauria, lea vino 1 P. muscorum the type of Pupilla. There is
