figs. 1-8. 



Description. — Zoarium consisting of irregular, explanate, layers which 

 by superimposition often form large masses. The individual layers vary 

 in thickness from 1 to 8 mm. and exhibit a strongly wrinkled epitheca on 

 the under surface. Zocecial apertures broadly oval; length .33 mm., width 

 .25 mm., irregularly disposed, sometimes in contact but most often sepa- 

 rated by vesiculose interspaces. Surface marked by macule whose centers 

 are distant from each other by about 6 mm. 



N"ot uncommon in the ]!v"ew Scotland limestone at several localities in 

 New York.

Genus FISTULIPORELLA Simpson i 



Description. — " Zoarium laminar or massive from superposition of suc- 

 cessive layers of growth; cells tubular; pseudoseptate ; apertures sub- 

 circular, enclosed in a sloping, polygonal, vestibular area. On the inter- 

 apertural surface, in addition to the vesicular cavities, are small oval 

 apertures, with equally elevated peristomes; intercellular space vesicu- 

 lose." Simpson, 1894. 



Type : Fistulipora constricta Hall. Hamilton of New York. 



The only peculiarity mentioned in the above description is the presence 

 of " small oval apertures, with equally elevated peristomes " on the ele- 

 vated interzocecial spaces. As the writers understand the type species, Mr. 

 Simpson failed to grasp the most essential characters distinguishing that 

 species, in common with a number of other forms, from other genera of
