114 THE NAUTILUS. 



greyish-olivaceous cuticle is confined to the apical whorls in the 

 adult : the " costulation " of the apical whorls is evident, and the 

 oblique striation of the last whorl above is very coarse and prominent. 

 Mountains near Kingston, New Mexico (O. B. Metcalfe). One 

 living adult and many dead shells, adult and young. Accompanied 

 by Ashmunella, Holospira, Vitrea, Helicodiscus, Vallonia and 

 Cochlicopa. 



NAMES IN THE PUPILLID^. 



BY W. H. DALL. 



In the January Nautilus (page 105), Dr. Pilsbry discusses this 

 subject, and incidentally states that in mv notes upon it in the Feb- 

 ruary number I corrected some errors, but complicated the question 

 " by a few new ones." I beg to submit, with all deference to Dr. 

 Pilsbry, that it is not I who have introduced the new errors. 



A more careful examination of Risso, Draparnaud and PfeifFer, 

 would have shown him that Jaminia muscoriim (Drap. not L.) Risso 

 is, as I stated, following Pfeiffer and other European authorities, 

 Pupa minutisslma Hartmann, and not mvscorum Linne. 



It would be presumptuous in me to attempt for myself a synonymy 

 of the ancient species of common European land shells, which have 

 been worked over with the utmost care for a century by a long line 

 of distinguished students. I did not attempt it, but relied on such 

 respectable authorities as Gray, Draparnaud, and especially Pfeiffer, 

 than whom no one was more careful, erudite, and familiar with the 

 subject. In working out the details of the nomenclature of Pupillidse 

 (a work still in MS.), involving a great amount of labor, I have, as a 

 rule, adopted Pfeiffer's conclusions as to specific identity as entitled 

 to greater weight than any others. 



The result of a careful historical search through the whole applic- 

 able literature differs in important particulars from Dr. Piisbry's 

 table in the January number. It is, of course, true, that Pfeiffer, 

 like other people, is not infallible, nevertheless conclusions based on 

 his identifications deserve a certain amount of respect, and should 

 not be stigmatized as new errors, even if some doubt continue to ex- 

 ist in occasional instances. 



Risso identified his species by Draparnaud's posthumous mono- 

 graph and its figui'es, occasionally citing Ferussac and Playfair, and.
