Remarks. — This shell, about the size of H. ramentosa, (Gould) can scarcely be con- 

 founded with any known species. It belongs to the Cyclostomoid group of Helices, 

 and has the aspect of a desert species. Dedicated to Philip P. Carpenter, L. L. D., 

 of Warrington, England. 



The name EinpJiragmopliora carpenteri has been apphed to a num- 

 ber of shells to which it did not belong. I believe that the three 

 specimens which Mi-. L. J. Goldman of the Biological Sm-vey collected 

 at Maricopa and McKittrick, on the east slope of the Coast Range, 

 belong here and will fix this fleeting name. 



The shells are characterized by a very naiTOw umbilicus, naiTOwer 

 than in any of the other races, except EpiphragmopJiora traskii 

 coelata. The incremental lines are rather coarse, while the wavy 

 spirally incised lines are fine and rather closely spaced. 



The two adult specimens measure: 



EPIPHRAGMOPHORA TRASKU PHLYCTAENA, new subspecies. 



Plate 115, figs. 1-3; 13-15. 



This is a rather large race in which the two whorls following the 

 nuclear turns are strongly papillose, the papillae being much more 

 numerous and much stronger than they are on the nuclear turns. 



Cat. No. 12363, U.S.N.M., contains two specimens, cotypes, col- 

 lected by W. G. Blunt, 40 miles north of Santa Barbara, CaUfornia. 

 One of these, an adult specimen, has six whorls, and measures — 

 greater diameter, 28.2 mm.; altitude, 17.1 mm. The other, not 

 quite matured, has only five turns, but in this the spiral sculpture 

 is better preserved and has furnished the illustration of that feature. 



The following specimens have been examined:
