NO. 3 CASSIDULOID ECHINOIDS — KIER 227 



Most of the species that have been referred by other authors to 

 Echinanthus are herein referred to Gitolampas. 



Genus JOLYCLYPUS Lambert 



Jolyclypus Lambert, 191 8. Mem. Soc. Acad. Aube, ser. 3, vol. 55, p. 26. Type 

 species by original designation, Galeropygus jolyi Gauthier. 



Remarks. — I was unable to find any specimens of the type species 

 of this genus. Lambert created this taxa as a subgenus of Galeropy- 

 gus from which it differs in having a more elongate test and higher 

 ambulacral plates. However, the species is based on a few very small 

 specimens which may be immature. I suspect that the age, supposed 

 to be Cenomanian, of this species is incorrect, as it appears to be far 

 too primitive. Until specimens of the type species can be reexamined, 

 it seems preferable to place this genus in incertae sedis. 



Genus LOVENILAMPAS Maury 



Lovenilampas Maury, 1934a. Amer. Mus. Nov., No. 744, p. 3. Type species by 

 original designation, Lovenia baixadoleitensis Maury. 



DESCRIPTION OF TYPE SPECIES 



LOVENILAMPAS BAIXADOLEITENSIS Maury 

 Plate 43, figures 9, 10 



Lovenia baixadoleitensis Maury, 1934b, Bull. Amer. Mus. Nat. Hist., vol. 67, 

 p. 156, pi. 15, fig. I. 



Remarks. — I have studied the type specimen in the American Mu- 

 seum of Natural History, New York. It is just a fragment of an 

 external cast of the area around the mouth. Maury did not realize 

 that the specimen was a cast, but considered it to be an internal mold. 

 The "extraordinary coating of cushions covering the inner surface 

 of the plates of the test" Maury describes are in reality only the 

 impressions made by the tubercles. It is not possible to refer this 

 Cretaceous (Turonian) fragment to a genus, but the phyllodes are 

 similar to those found in Pygorhynchus. 



Genus OVULECHINUS Lambert 



Ovulechimis Lambert, 1920a. Mem. Soc. Acad. Aube, vol. 84, pp. 148, 149. 

 Type species by original designation, Ovulechimis pilula Lambert (op. cit., 

 pp. 148, 149, pi. I, figs. 7-9. 



Remarks. — This genus is based on one species, represented by two 

 very poorly preserved and probably immature specimens. These
