Bryozoans of tlie 



intercellular space are granulose; sometimes the margins are in con- 

 tact, coalescing, and forming elevated angular nodose ridges.

Trematopora? granistriata, iu sp. 

 Consisting of elongate stems with striated base, apparently simple, 

 attached to foreign substances by wrinkled rootlets. The stem for 7 

 mm. is small, striated; cells tubular, cylindrical; apertures oval or 

 circular; length .38 mm., arranged in longitudinal parallel rows, fre- 

 quently alternating and forming oblique rows ; space between longi- 

 tudinal rows, with linear granulose striations; sometimes from mu- 

 tual pressure the apertures are polygonal.

CALLOPORA, Hall 



Callopora bispinulata, n. sp. 

 Eamose, solid; branches infrequent; diameter 1 mm., expanding 

 and flattened before bifurcating; cells tubular, subcylindrical ; aper- 

 tures oval; length .35 mm., closely disposed, some portion of the mar- 

 gins of adjacent apertures in contact ; sometimes in regular longi- 

 tudinal and oblique rows, the margins having at each end a minute 

 spine; space between apertures with minute pits; as the arrangement 

 of the apertures vary, the bryozoan presents a very variable appear- 

 ance. 



Locality—Moscow, 'N. Y. 



Callopora HAMiLTo:s^EisSis. 

 Ceriopora 9 JIa?nilto)iensis, Kicliolson. 

 Ramose, solid; diameter 1 mm.; cell-apertures oval; length .25 

 mm., arranged in parallel longitudinal rows, alternating, and forming 

 transverse oblique rows ; margins slightly elevated ; longitudinal ranges 

 separated by a strong ridge ; the transverse space between the aper- 

 tures is occupied by two quadrangular pits. 



Locality — Hamburg and New Berlin, Y. 



Callopora in^ter^^odata, n. sp. 

 Ramose, solid ; diameter 2 mm. ; cells tubular, subcylindrical ; ap« 

 ertures oval; length .33 mm., elevated margins frequently in contact, 

 sometimes irregularly disposed, at other times arranged in trans- 

 versely oblique parallel rows; intermediate space occupied by minute
