Corrections to the

nomenclature

of the

Eocene

fossil corals of the United States.

Since the publication^of

my

^{Eocene and}

^Lower

Oligocene^coralfaunas of theUnitedStatesin 1900, as

Monograph XXXIX

oftheU.S.Geologi- cal Survey, ^{I find it} necessary^to

make

several changes ^{in the}

names

there used.

Professor T. D. A. Cockerell has called

my

^{attention to the fact that}

Coquilett applied^this

name

my

^mistakeafter the publication ^of the

Mono-

The

genus Endopachys has been characterized as showing

no

evidence of attachment.

My

Rhectopsammia ^{is the} attached

young

^of Endopachys. These

young

individuals often attain aheight ^{of 6}

mm.,

then the upper portion ^of the corallum

becomes

_separated ^{from the}

pedicel. Indications of the

detachment

may

frequently be seen quite^{late in} the lifeof

some

_specimens. Usually^{it is}ultimately

uses the

name

Paracyathusgranulosus,butthe

name

^isnot

accompanied by

^any description. ^I have

made

a careful search for a published ^de- scription^ofthe species referredto, but have not been able to find any.

IhavewrittentoProfessorVerrill forinformationregarding the matter.

He

says that

some

noraina

_escapedhis attention in preparing ^the

lists fortheFish Commission, although he endeavored ^{toeliminate all} of them. Therefore

my ^name

Paracyathus granulosus ^will stand,

and when

ProfessorYerrill publishes the descriptionof his coral it will be necessary^for

him

togive^itanother name.
