148. A. grisea NeWC. Zool. Proc. pi. 24, fig. 66. 1853. 

 " radiata Pfr. non Gould. Mai. Blat. 1854, p. 117. 



This species, from the island of Maui only, has a reference 

 in Mai. Blat. to " Waianae, Oaliu," which is an error of suffi- 

 cient importance to be corrected. The proportions of this spe- 

 cies are constantly different from the preceding ; the aperture 

 much larger, and the last whorl much more inflated. 



149. JUastersi ]\eWC. Zool. Proc. pi. 24, fig. 67. 1853. 

 " rubens var. Pfr. non Gould. Mai. Blat. 1854, p. 129. 



Animal longer than the shell, of a fine flesh-color, covered 

 with granulations tipped with carmine ; tentacles and anterior 

 superior portion of the body dark brown or black; motions 

 fearless and active. Compare this description of the animal 

 with that of rubens Gould, and add that the one is an inhabit- 

 ant of bushes (the "Olona"), the other always burrowing, and 

 we shall find no two animals of the genus wider apart than these. 



A. Mastersi is an inhabitant of Molokai, and is sparsely 

 found on Maui.
