KENTUCKY GEOLOGICAL SURVEY. 55 



American Association for the Advancement of Science, pp. 19- 

 24, was overlooked. In this paper, a communication presented 

 before the meeting by the secretary, Van Cleve describes his 

 work upon the western zoophytes. Copies of plates of figures 

 which he had prepared were exhibited. Van Cleve's death pre- 

 vented the publication of his work. A few copies o.f the plates sur- 

 vived. The illustrations were later reproduced in the Eleventh 

 Annual Report of the Indiana Geological and Natural History 

 Survey, 1882. In the list which Van Cleve gave of forms fig- 

 ured appears "Ceriopora constellata n. sp., blue limestone, Day- 

 ton, Ohio." Dana in 1846 established the genus Constellaria, 

 with the remark that a "species of this genus is named Cerio- 

 pora constellata on the plates of Western fossils by Van Cleve." 

 Dana gave no locality and mentioned no other species. Hence 

 it Avas supposed that the common form at Cincinnati, which 

 later passed current as Stellipora antheloidea Hall, was the form 

 which Dana and Van Cleve had in view, and so it was concluded 

 that Ulrica's Constellaria florida was a synonym. Now that it 

 is known that Van Cleve's material came from the vicinity of 

 Dayton, Ohio, and as it is- uncertain that Dana had any speci- 

 mens before him, Ulricas name must be regarded as valid. Van 

 Cleve's form is one of the Richmond species of Constellaria. 



Occurrence: At Cincinnati, Ohio, and Covington and New- 

 port, Ky., the C. florida appears in the middle part of the Fair- 

 mount beds of the Maysville group. About 30 or 40 feet inter- 

 vene between the horizon of C. florida, and that of C. prominens, 

 in which interval no examples^ of Constellaria have yet been 

 found. Examples of the C. florida were collected also at Mt. 

 Sterling, Ky.
