[Vol. XXII, 



zocecia this spine becomes trifid, one branch usually extending 

 outward, one upward and one downward. No oacia have been 

 found. 



This species was obtained from Amoy, China. No other data 

 given. The material incrusts a shell which is judged to be from 

 water only slightly saline since, while calcareous, it is extremely 

 soft and chalk-like and not of the ordinary marine type.

32. Membranipora devinensis, sp. nov. 



Zoariuin incrusting bark of sodden wood, loosely attached. 

 Zocecia elongated, sometimes of extreme length and connected 

 together loosely (fig. 7). Aperture occupying almost all of the 

 front, the margin beset with a large number of spines which meet 

 across the front. Opcrculmn semicircular, large at the top of the 

 aperture. The portion of the zooecium below the aperture covered 

 with a delicate calcareous wall marked by two large pores. Some- 

 times two zocecia form in the place of one, when each zooecium 

 possesses but one pore. In no case has a spine been found project- 

 ing from these pores. Ocecium small, projecting over the zooecium 

 above, alrnost to its pores.
