NERITA. Panama Shells. 205 



Most of our specimens are of a uniform jet black color, with 

 the exception of the eroded spire. Some are sparingly mottled 

 with cream colored spots, and a few specimens have some small 

 bright red spots on or near the labrum. Several are elegantly 

 banded with narrow or broad spiral stripes of cream or orange 

 colors. The young are more or less profusely mottled with 

 white, grey, and greyish black. 



Station. On rocks between high water and three-quarter 

 tide levels. They are especially disposed to collect in the 

 crevices of rocks. The young are commonly seen crawling 

 above high water mark, where the rocks and stones are wet 

 with spray. 



Habitat. Unknown ; Lamarck: also Wood.

 California; Philippi.

Panama and Taboga; C. B. A.! 

 We collected 400 specimens on the reef. 

 Probably the statement of habitat (I. of Timor,) by Recluz is 

 erroneous. It was taken from the label of the Lamarckian 

 specimen (long supposed to be unique) in the Massena Collec- 

 tion.
