Shell resembling Frieleia, Dall, from which it Jitters iu type of cardiimlia and 

 folding. The cardinalia consist of two divergent socket-ridges united to the crural 

 bases by transversely striated curved lamella). From the inner sides of the crural 

 bases two curved lamella) extend to the floor of the valve, where they become 

 fused to a posterior bifurcation of a short but well-defined mesial septum. Crura 

 short, abruptly truncate or slightly denticulate. No obvious cardinal process. Dental 

 plates and a pedicle-collar present in ventral valve. Surface of valves with hair-like 

 radii. Folding dorsally uniplicate. Genotype : RIti/ncln>ut'U<i i-<irvitza>, Joubin.

'M*. Several examples of a finely-ribbed, thin-shelled Rhyuehouellid were trawled 

 at each of the above stations. Nearly all are empty shells in the adult stage of 

 growth, and only three or four half-grown examples contain the imperfect remains 

 of the animal. Tliese latter are attached to fragments of Polyzoa. 



The specific determination of this form has been considerably hampered by the 

 inaccessibility (owing to the European conflict) of certain type specimens preserved in 



museums at Paris and Brussels.
