In this island subspecies the incremental lines are much stronger 

 and the spirally incised lines are much wider and more deeply cut than 

 in the other races. The combination of these sculptural elements 

 give a clothlike texture to the entire surface of the shell. 



I have examined the following adult specimens: 



EPIPHRAGMOPHORA TRASKH COELATA, new subspecies. 



Plate 115, figs. 7-9; plate 117, fig. 10. 



This is a small decidedly inflated race having the inner lip reflected 

 over the very narrow umbilicus covering this half or more than half. 

 All the whorls excepting the last turn are papillose. The spirally 

 incised sculpture is feeble on the upper side of the last one and one- 

 half whorls, and scarcely indicated on the base of the last turn. 



The type and another specimen, (Cat. No. 124747, U.S.N.M.) come 

 from the Mesa, at Pacific Beach, California. The type has five and 

 one-third whorls, and measures — greater diameter, 20.8 mm.; alti- 

 tude, 13.7 mm. The other specimen has four and one-half whorls 

 and measures — greater diameter, 21.8 mm.; altitude, 13.5 mm.

This race was described by Newcomb in the following terms: 



Shell umbilicate, roundly conical; apex obtuse, obscurely marked with one brown 

 band; well striated; under the lens numerous very minute spiral striations; whorls five 

 and one-half rounded; suture well marked; apertiu*e circular, with margins approxi- 

 mating; lip moderately expanded, at the columella broadly so, but not adherent. 

 Diameter, 23 mm.; altitude, 16^ mm. Habitat "Tulaie Valley." Mus. Cal. Acad.
