Conopeum reticulatum Linne 

 ( Me mb ranipora lacro ixii A udouin ) 



PLATE X. Fig. 1 



An encrusting form somewhat similar to the 

 above ; usually with no spines whatever ; occasionally 

 with a few very slender erect spinules. 



Encrusts pebbles, etc., along entire Eastern 

 Coast. 



Schizoporella unicornis Johnston 



PLATE IX. Pig. 6; PLATE X. Fig. 4 



The most abundant of the encrusting bryozoa in 

 New Jersey. Encrusts pebbles, shells, etc., and some- 

 times reaches a considerable size and may be many 

 layers in thickness. 



Zooecia roughly hexagonal or rectangular, punc- 

 tured with a variable number of small pores. Orifice 

 or opening approximately circular with a prominent 

 indentation; very variable in form. Usually pink 

 when living but turns to gray when dried. 



Because of its frequent massive appearance this 

 form is often erroneously called "Coral."

 Cod to South Carolina.
