6. ^S*. intermedia, n.s]). 



Zoa?cia clong-atcd, separated by very fine raised lines, a row of large round 

 pores aluny the margins ; tliyrostome rounded above, contracted below, and having 

 a squared median denticle; four large spines on the iij)per edge; immediately below 

 the lower li]) a round })ore which is probably avicularian. Immediately above the 

 tliyrostome is a circumscribed area, the front wall l)rolien in the specimens, Avhich is 

 probably avicularian.

Zoariuni crustaccous. Zotecia distinct, separated by narrow raised lines with a 

 row of areolations close to the margins; thyrostome somewhat triangular, with a 

 long s[)out-like sinus below ; tlu'ce spines above and a broad median denticle on the 

 lower lip; on one side of the sinus a long raised avicularium extending half-way or 

 more up the aperture and frequently obscuring the sinus, the mandible directed 

 upwards. Ocecia globular, usually with two fenestrse or areolations.
