«Shell of medium size, inequivalve and somewhat oblique; surface markings consist of: (a) about 5 or 6 primary radii, heavily spined, (b) 5 to 10 secondary radii between the primaries, the middle one having a tendency to be strongest, (c) finer radii of various sizes; all radii strongly fimbriate or scaly.
Dr. Maury has given an excellent and detailed description of her Spondylus lucasi ¹ and it would appear that lucasi and falconensis have much in common in detailed structure; but the small size of lucasi and its seeming lack of a half-dozen strongly spinose primary radii suggest noteworthy differences. Since the largest dimension for lucasi is 33 mm. and falconensis easily reaches 100 mm., we are dealing either with different species or very different stages of development in specimens. What is needed at present is good, enlarged, photographic illustrations of the exterior characteristics of lucasi. The general aspect of the species is like that of S. bostrychites Sowerby as interpreted by Maury,² or S. chiriquiensis Olsson.³ Age: Miocene. Locality: Districts of Colina and Miranda, State of Falcon, locality numbers 121, 151, 180, 182, 206, 275, 1012..» ¹ Scient. Surv., N. Y. Acad. Sci., vol 3, 1920.
