MARINE POLYZOA. 81 



The figures given in this Catalogue will convey some idea of 

 the multiplicity of forms assumed by this protean species.

36. LEPRALIA CUCULLATA, n. s.? PL XCVI. figs. 4, 5. 



Cells ovate, black, surface granular ; mouth looking forwards, 

 orbicular, upper margin usually arching over like a hood. Ovi-

Egypt, pi. 8. fig. 6 (non Lamouroux). 

 Hab. Egean Sea, E. Forbes. 



In the absence of ovicells in the specimens in my possession, 

 it is impossible to determine whether or no the present is identical 

 with the species figured by Savigny, to which however, in other 

 respects, it bears a very close resemblance. This form, although 

 named by Audouin Mangnevillana, is clearly not the one in- 

 tended by Lamouroux under that appellation (vid. Polyp. Flex. 

 p. 890. pi. 1. fig. 3. a. B). A species of the same black colour, 

 and in all respects resembling the present except in the less 

 obliquity of the mouth and the absence of the raised upper 

 border, occurs in Gibraltar Bay (Dr. Landsborough). The latter 

 form is verv like L. reticulata.
