Atooi [= Kauai] Conrad. Kaena, Kauai and Honolulu 

 Harbor, W. E. and E. L. Bryan. Kewalo beach, east of Hon- 

 olulu, Pilsbry. "Shell short fusiform, ventricose, with longi- 

 tudinal undulations and spiral costse; whorls with crowded 

 spiral foliated strise; labrum costate within, margin foliated ; 

 columella with an obtuse or obsolete fold. Inhabits the Island 

 of Atooi " ( Conrad. ) 



We do not know that this species has been recognized hitherto, 

 though it was quite recognizably described and figured. Tryon 

 in Manual of Conchology, vol. 2, considered it a synonym of 

 the very different Coralliophila bulbiformis (Conrad). It has 

 been found in some abundance in material dredged from Hono- 

 lulu Harbor, by Professor and Mrs. Bryan, and the senior 

 writer picked up a living specimen on the reef at Kewalo. 



The shape is rather variable, as shown in the figures. The 

 longitudinal folds, eight or ten on the last whorl, are crossed by 

 four or five larger cords and numerous small threads. The 

 cords and intervals are densely, minutely scaly, the whole shell 

 being particularly rough and prickly. The shoulder is either 

 nodular, or in some specimens spinose. There are about seven 

 well developed teeth within the outer lip. The columella is 

 heavy, straight, with a small, blunt, median prominence, re- 

 calling the fold of Cymia on a small scale. 



The ground tint varies from light buff to pallid neutral gray, 

 the summits of the folds and spines or tubercles being dull 

 dark vinaceous. The aperture varies from fawn color to nearly 

 white. 



Two specimens measure: 

 Length 33.5, diam. 21.5 mm. 

 Length 28.5, diam. 21.5 mm. 



There is also a small specimen in the Bryan collection from 

 Ocean Island, collected by Capt. J. H. Brown.
