Every one of these band varieties is known from the Lex- 

 ington colony (c/. J. L. Howe, American Naturalist, Dec, 

 1898). Among 102 shells are two with split or extra bands, 

 which is scarcely half the percentage of such forms in the 

 Lexington colony. It would require a much larger collection 

 to show whether this is accidental. The absence of the vari- 

 eties with a pink ground, of which 40 are reported from Lex- 

 ington, is remarkable. 



DESCBIPTION OF A NEW PANDORA OF THE SUBGENUS KENNERLYIA 

 FROM FORRESTER ISLAND, ALASKA. 



BY GEORGE WILLETT. 



During the summers of 1916 and 1917 a Kennerlyia which 

 seems to differ materially from previously known species of 

 the subgenus was taken by the writer at Forrester Island, 

 southeastern Alaska, at an average depth of about fifty 

 fathoms. A considerable number of living specimens were 

 secured and, when carefully compared with specimens of 

 allied species, certain distinctive characteristics seem to be 

 maintained throughout the series. Therefore I propose for 

 this shell the following name : 



Kennerlyia forresterensis, new species. 



Shell moderately heavy; short and deep (depth in twelve 

 typical specimens averaging .67 of length). Color white, with 

 brownish periostracum generally visible on both ends but 

 most conspicuous on posterior. Left valve moderately convex, 

 smooth except for rather faint incremental lines. Right valve 

 flat or slightly convex, except near basal margin where it be- 

 comes abruptly concave ; smooth except for several ( generally 

 7-9) irregular impressed lines running from apex to basal
