Synonym of GITOLAMPAS 



Section Gitolainpopsis Checchia-Rispoli, 1921. Mem. Descr. Carta Gcol. d'ltalia, 

 vol. 8, pt. 2, p. 18. Type species, Gitolampas lamherti Checchia-Rispoli (op. 

 cit.), by subsequent designation, Kier, herein. 



Remarks. — Checchia-Rispoli proposed this section for his two 

 Species G. lamherti and G. .■:uffardii from the Senonian of Tripolitania. 

 He distinguished this section from the typical Gitolampas by its 

 higher test and more dorsally situated periproct. I have not seen 

 any specimens of the type species, but Checchia-Rispoli's photographs 

 are excellent and permit a comparison of G. lamherti with the type 

 species of Gitolampas, G. tunetana. The periproct in both species is 

 situated in approximately the same position and is not more dorsal in 

 G. lamherti. Gauthier's and Cotteau's figures of G. tunetana show 

 the periproct in a more ventral position than it really is. It is true 

 that the test is higher in G. lamherti, but this character is not of 

 sufficient importance to warrant subgeneric distinction. 



Genus DARADASTER Tessier 



Daradaster Tessier, 1952. Bull. Dir. Mines, No. 14, p. 295. Type species by 

 nionotypy, Daradaslcr pcroni Tessier. 



GENERIC DESCRIPTION 



Test medium size, elongate, low, apical system very large, mono- 

 basal, with genital pores widely separated from each other; petals 

 extremely broad, closed, with poriferous zones of same petal widely 

 separated near apical system ; interporiferous zones extremely wide ; 

 periproct marginal, peristome anterior, width equal to height; phyl- 

 lodes single pored, greatly widened; bourrelets very strongly devel- 

 oped, extending into peristome, toothlike. 



Comparison with other genera. — This Eocene genus is similar in 

 shape and petal arrangement to some species of Gitolampas but differs 

 in having more strongly developed bourrelets, and a much larger 

 apical system. I was not able to study any specimens of this genus 

 and therefore have included no description of Tessier's (1952, p. 295, 

 pi. 15, figs. 13-15) type species. 



Genus EURHODIA Haime 



Eurhodia Haime, in d'Archiac and Haime, 1853. Descr. animaux foss. Inde, 



p. 213. Type species by monotypy, Eurhodia morrisi Haime.
