Diagnosis. 
Zoarium of slender branches, which divide dichotomously and 
bear short lateral processes, which are distant and either 
opposite or alternate, and remain in the same plane as the stem. 
Obverse surface regularly rounded. 
Eeverse surface with numerous longitudinal, fine, raised lines, 
between which are lines of pores, or it may be covered by a non- 
porous layer, which is transversely wrinkled. 
Distribution. 
Lower Senonian — Iserschichten : Gross Ujezd, Vetelno, Bohemia. 
ArriNiTiES. 
This species is a near ally of H. striatus (Hag.), the Truncatula 
gracilis, d’Orb. (p. 97), from which it differs most definitely by the 
wide separation of the lateral processes in H. tenuis, whereas in 
H. striatus they are so close together that they overlap.
