NOTES ON FOSSIL BARNACLES. 



The limits of this work do not allow of an}- discussion of the Ameri- 

 can tertiary barnacles, except in the case of Balanus concavus, which 

 also occurs as a recent species. On account of the importance of the 

 subject, some notes are given on supposed Palaeozoic Balaiiidai. 



Protohalanus hamiltonensis Whitfield ^ from the Marcellus shale, 

 Hamilton group of the Devonian of New York, is described as having 

 12 wall plates and perhaps 7 opercular valves. It has a certain 

 superficial resemblance to Balanus, but is morphologically inconsistent 

 with the Balanomorph barnacles. I doubt very much whether Proto- 

 halanus is a cirripede, but if so it must represent a group unrelated 

 to any known Mesozoic or later form.
