See Canu and Bassler, 1920 and 1923, for description of this family 

 and its genera.

Measurements. — 



r. • |^o = 0.16 mm. v • \Lz = 0.60-0.70 mm. 



Opesium 7 Zooecia , 



Uo = 0.14 mm. 1/2 = 0.40-0.44 mm. 



Levinsen, 1909, divided his species in three varieties as follows: 



(A) Var. stapijera (pi. 6, fig. 5); (B); (C) V&r.tubifera (pi. 6a, fig. 2). 



Harmer, 1926, studying the same material believed there are three 



distinct species and preserves the name of granulata for variety B 



which is precisely the species which we have found. It is very well 



characterized by the duck bill form of the interzooecial avicularia. 



He does not think that Thalamoporella granulata Osburn 1914 from 



the Gulf of Mexico and T. granulata Canu and Bassler, 1919, from the 



Miocene of San Domingo are correctly determined. We likewise feel 



doubtful of our own determination. 



Our specimens were unilamellar or encrusting bryozoan fronds 



(Adeonellopsis) ; they were dead. Between the granules of the 



cryptocyst there are very small pores.
