THE NAUTILUS. 2^ 



numbers of species in different parts of the areas covered by the 

 genera have been added by Mr. Gratacap. To some extent these 

 charts indicate, incidentally, areas in which but little collecting has 

 been done. This is especially the case with plate xlii, representing 

 the distribution of typical Polygyra. 



The following names seem to be new to us: 



Glandina truncata var. minor Binney MS. (p. 338, Cat. no. 16)^ 

 Based upon ^'Variety of Glandina Texasiana Pfr.%'" Terr. Moll. iv,. 

 pp. 141, 205, pi. 77, f. 21. Seems to be a very slender specimen of 

 G. truncata minor Pils., Nautilus xiii, p. 46 ; Proc. A. N. S., Phila., 

 1899, p. 404. 



Macrocyclis vancouverensis var. semi-decussata Binney on label (p. 

 340). Astoria, Oregon. This is doubtless identical with Gircinaria 

 spartella hybrida Anc, which we have from Astoria. 



M. concava var. minor (p. 341). No locality or definition. 



Zoniles {Gastrodonta) ligems var. sagdinoides Gratacap (p. 344). 

 "A very high 'bee-iiive ' form from Indiana." 



Zonites {Hyalinn) placentidu Shuttl. (p. 350), Catal. no. 294 was 

 Binney's earlier identification of placentida, subsequently becoming 

 tiie type of Z. law^. The specimens from Monroe Co., Tenn., and 

 St. Giles Co., Va., are true placentida, as afterward identified l>y 

 Binney. Through the kindness of Mr, Gratacap, I have been able 

 to examine this series. 



Helix (Patida) allernata var. costigera Bid. MS. (p. 357). 



Helix (^Patida) perspectiva "var. carinata (p. 358) from Union Co.. 

 Tenn., is almost planate, and below the periphery the strire approach 

 extinction." Under H. (P.) bryatiti, Mr. Gratacap writes, " Cer- 

 tainly interchangeable with var. carinata o'i perspectiva." 



Triodopsis midlani (Bland), Ca'. no. 1275 (p. 383), can hardly Ik- 

 that species. 



3Iacrocerumus (p. 31)7). The specimens recorded under M. pon- 

 tificus as from Texas are probably M. texanics. That from Central 

 America is no doubt kieneri, as recorded by Mr. Gratacap (see Man. 

 Amer. Land Shells, p. 41 G, fig. 457) H. A. P. 



Some Undesckibed Varieties of Cyi-r.^a. — By Mrs. Agnes 

 Kenyon (Jour, of Conchology, Vol. X, p. 6, April, 1902). — In this 

 |i;iper the following varieties are described as new : 



Cyprcea tigris var. liueuta. From Fiji. Differs from the type in 

 possessing a number of longitudinal hair-like lines.
