approximately the same size as the specimens of Tennieria henrici 

 had only slightly crowded phyllodes with very few sphaeridia, whereas 

 in the larger specimens the pores in the phyllodes were very crowded 

 and the sphaeridia very numerous. 



Range and distribution. — Upper Cretaceous (Maestrichtian) of 

 Morocco. Mortensen (1948, p. 329 and explanation to text fig. 308) 

 refers Duncan and Sladen's Echinanthits enormis from the Paleocene 

 of India to Tennieria. It only resembles T. henrici in its short petal 

 III, but in all other characters is quite distinct. The petals in E. 

 enormis are longer, narrower, with narrower poriferous zones; the 

 phyllodes are much more developed, with two series of pores in each 

 half-ambulacrum, bourrelets strongly developed, and the test higher. 

 This Indian species seems distinct from any other genus, but as I 

 have seen no specimens of this species, I hesitate to erect a new 

 genus for it. 



DESCRIPTION OF TYPE SPECIES 



TERMIERIA HENRICI Lambert 



Plate 37, figures 5-7 ; text figure 165 



Tennieria henrici Lambert, 1931. Mem. Soc. Geo!. France, vol. 7, p. 31, pi. i, 

 figs. 31-35- 



Material. — I have studied the only two specimens, syntypes, known 

 of this species. I designate as lectotype the specimen figured by 

 Lambert (1931) on his plate i, figures 31-34. This specimen is well 

 preserved adapically and shows the petals clearly. The other speci- 

 men, a figured paratype (Lambert, op. cit., pi. i, fig. 35) is poorly 

 preserved adapically but shows clearly the peristomal region. Appar- 

 ently no other specimens are known of this species. 



Shape. — Small, lectotype 14.3 mm. long, elongate, with greatest 

 width posterior to center, low posteriorly, inflated anteriorly, with 

 greatest height near anterior margin ; adoral surface flattened, with 

 peristome slightly depressed ; posterior margin pointed. 



Apical system. — Anterior, monobasal. 



Ambulacra. — Petals broad, with tendency to close distally, of un- 

 equal length ; posterior petals I and V extending slightly more than 

 one-half distance from apical system to posterior margin, 21 pore 

 pairs in each poriferous zone in lectotype; petals II and IV almost 

 transverse, shorter than posterior petals, with 16 pore pairs in each 

 poriferous zone ; petal III very short, less than one-half length of 

 petals II and IV, with 9 pore pairs in each poriferous zone; both
