A new fossil fucoid 
ARTHUR HOLLICK 
(WITH PLATE 33) 
Among a number of unidentified specimens recently subjected 
to critical examination in connection with the work of arranging 
the paleobotanical museum of the New York Botanical Garden, 
was one of an unusually well-defined, almost perfect frond of a 
fucoid. The original label reads ‘‘ Haliserites sp. (near H. De- 
chenianus Gépp.). Devonian. Franklin, Delaware Co., N. Y.”; 
but neither the name of the collector nor the date of collection is 
recorded. 
The locality indicated is within the Devonian area of the state, 
and the specimen, if dismembered, would resemble very closely, 
in its parts, certain Devonian fucoid remains from the same 
general region, referred to the genus Haliserites by D. P. Pen- 
hallow.* In the paper cited a number of fragmentary specimens 
are described and figured under the names Haliserites Dechenianus 
Goépp., H. Dechenianus lineatus var. nov., and H. lineatus sp. 
nov. They apparently merely represent different parts of a single 
species, and if all were combined the combination would resemble 
quite closely a portion of the specimen now under consideration. 
They are all described as having dichotomously forked branches— 
the only specific differences being the characters described, re- 
spectively, as “equally and strongly costate throughout,” “midrib 
well-defined throughout”’ and ‘“‘costate throughout, costa not promi- 
nent.”’ The figures, however, fail to show these latter characters 
in a satisfactory manner in any instance and none of them gives 
any idea of the size or shape of the frond. Under the circum- 
stances, therefore, it would be inadvisable to assume specific iden- 
tity between our specimen and any one or all of these fragmentary 
remains, although it would be entirely justifiable to regard them 
as identical generically.
