144 THE NAUTILUS. 



(Records Australian Mus., vol. 7, pp. 260-266, pis. 73 and 74, 

 1909.) Four species are descnl)ed as new. 



A Revised census of the Tekkestuial Mollusca of Tas- 

 mania. By W. F. Petteud and C. Hedley. (Records Aus- 

 tralian Museum, vol. 7, pp. 283-304, pis. S2-87, 1909.) A com- 

 plete revision of the species, vk'itli illustrations of all Tasmanian land 

 shells hitherto unfigured. Cystopelta bicolor is described. 



The list of San Bernardino County mollusks in the November 

 number of The Nautilus (Vol. XXIll, pp. 73-79) does not in- 

 clude Lymncea buUinoides techella Hald. I found this sjjecies in con- 

 sideral)le numbers during the summer of 1909, in Sec. 33, Tp. 2 S., 

 R. 7 W., very near the county line, but the owner assures me that 

 his property is in San Bernardino County. They were in a pond 

 surrounding an artesian well. Dr. Frank C. Baker identified the 

 specimens Junius Henderson, Boulder, Colo. 



Note on the Summary of the Mollu&ca of the Peruvian 



Province There are some points in Mr. Berry's review of this 



paper which show that even those things which are obvious, or seem 

 to be so, should not be omitted. In preparing this list it was not 

 my intention to review the whole molluscan classification or nomen- 

 clature, which would have taken as many years as the list I prepared 

 look months. In those groups which are not familiar to me, I fell 

 back on the only modern classified lists of the Cephalopods and 

 Nudil>ranclis, namely those of Hoyle and Bergh, as indicated in my 

 bibliography ; the experience and reputation of these authors being 

 such as to require no apology for accepting their results. In the 

 case of the BoHlsena I followed the spelling of the name as given in 

 the work referred to, the Bulletin of the Museum of Comparative 

 Zoology. Polypus fontaineanus was named after N. Fontaine, and 

 though it happened to be misprinted fonlanianus in the first fasci- 

 culus of Orbigny's work, and this misprint was copied on the plate 

 by the engraver, the error was corrected in the index of the book 

 somewhat later. Under these circumstances we are authorized by 

 the rules to accept the correction, as Mr. Berry proposes to do in 

 the case of Turridse. However in the latter case since the deriva- 

 tives of Turn's in Latin {turritus) English (turrited) and so far as I 

 know all other languages, accept the euphonic " t " in derivatives of 

 Turris, I kept the earlier form which is more in harmonj with 

 TurrilellidcB and similar accepted locutions. The illustrations of the 

 work were intended for those interested in the identification of the 

 economic shellfish and not for anatomists, and for this purpose 

 Orbigny's plates are quite satisfactory. As Whewell remarked "We 

 are none of us infallible, not even the youngest of us." — Wtn. H.
