on the west coast. In both places it was found associated with 

 .Alcyna rubra. It has not been reported from any island but Oahu. 

 It differs from other Hawaiian species of the genus by its longer, 

 ovate contour. The patterns vary widely. An average specimen 

 measures: 



Length 2.7, diam. 2, longest axis of aperture 1.5 mm.; 4 whorls. 



Phasianella variabilis kahoolawensis n subsp. PI. X^^ fig. 11. 



The shell is perforate, pinkish-buff with pink lineolation, the first 

 whorl opaque white; thin. 



Length 1.8, diam. 1.45, longest axis of aperture 1 mm.; 3^ whorls. 



Kahoolawe, the type, No. 116188, from the north shore; another 

 specimen from Smuggler's Bay on the southern shore; collected by 

 Pilsbry, 1913. 



This is probably a distinct species. It is thinner, with a thinner 

 columella than young P. variabilis of the same size. I did not find 

 variabilis on the island of Kahoolawe. 



Phasianella bryani n. sp. PI. XV, fig. 13. 



The shell is narrowly perforate, short and broad, rather solid, 

 smooth, nearly white, closely, obliquely lineolate with pale rose. 

 Spire short. Whorls well rounded, rapidly increasing. Aperture 

 oblique, nearly round. Columella rather thin, not prominent at 

 its junction with the basal margin. 



Length 2.4, diam. 2.1, longest axis of aperture 1.54 mm.; 3| whorls. 



Haleiwa, west coast of Oahu. Type and paratypes No. 116320, 

 A. N. S. P., collected by Pilsbry, 1913. 



This species occurred with P. variabilis, from which it is readily 

 separable by the shorter spire and relatively broader last whorl. 

 The groove behind the columella is much narrower than in P. molo- 

 kaiensis, and the shell is thicker. Some examples have opaque white 

 spots below the suture. It is named for the author of Natural 

 History of Hawaii, who was my companion and guide on several 

 collecting trips to the reefs of Oahu. 



Phasianella molokaiensis n. sp. PI. XV, fig. 10. 



The shell is thin, narrowly umbilicate, globosely ovate, smooth 

 and glossy, the type having old rose spots below the suture, irregular 

 spots below the periphery, and a lineolate band between, on a whitish 

 ground. The aperture is nearly round, oblique, showing the color 

 through; outer lip thin; columella thin, a deep and wide groove 

 behind it. 



Length 2, diam. 1.7, longest axis of aperture 1.27 mm.; 3| whorls.
