304 CANON A. M. NOKMAN ON THE POLYZOA 



small with a sinus on tlie lower lip, and eight marginal spines. Surface o£ 

 zooecium punctate, and a few scattered punctures larger than the rest. 

 Avicularian (or vibracular) openings on each side below the aperture with a 

 central bar. Ooecium remarkably small as compared with the breadth of the 

 zooecium, well raised and distinctly punctated. Colour of dead specimen 

 pure white. 



A single specimen attached to the telegraphic cable, sent to me by Senhor 

 De Noronha, after whom I name the species, in the spring of 1908. 



This comes perhaps near to Scliizoporella RicJiardi, Jullien and Calvet 

 (p. .140, pi. xvi. fig. 6), but in that species there is only a single avicularium 

 and that central just below the sinus, and the ooecium is quite different in 

 sculpture. 



SCHIZOPOKELLA SCHMITZI, n. Sp. (PI. 41. fig. 2.) 



Zooecia somewhat longer than broad, only moderately convex, surface 

 smooth with scattered conspicuous pores. Oral opening as broad or broader 

 than long (exclusive of sinus), sinus not narrow but sharply defined at the 

 corners, spines on the narrow margin apparently about four, Avicularium 

 of large size on one side a little below the lower lip ; the bar not persistent 

 but in one instance it is still to be seen perfect. 



One specimen pure white and the whole texture delicate, apparently not 

 lono- dead on a shell of Pectunculus. 



Named after Padre Schmitz, who has done so much to promote the study of 

 Natural History among the Portuguese at Madeira. 



This species is somewhat like Lace^ma hosteensis, Jullien (Miss. Sci. Cap 

 Horn, Bryoz. 1888, p. 48, pi. i. fig. 2), but in that species the pores are 

 represented as confined to the sides of the zoarium, and there is no 

 avicularium. 



EscHAEOiDES COGCINEA {Abildgaard). W. 



This is Lepralia appensa, Hassall. For this use of Escliaro'uies see Norman, 

 Ann. & Mag. Nat. Hist. ser. 1, vol. xii. 1903, p. 116. 

 Two small specimens on shell. 



ESCHAKELLA OBSCURA, n. Sp. (PI. 40. fig. 8.) 



A curious species of which I have only found a single specimen. It 

 consists of a basal layer, slightly granulated, and marked with very fine 

 microscopic crescentic lines. On this basal layer there is no indication of 

 separate zooecia further than that from it rise papillae surmounted by an oral 

 orifice looking directly upwards ; the orifice is irregularly round in form, and 

 the lower lip is characterised by a' well pronounced denticle just within it. 

 In some instances the back of the papillte is swollen in a manner which may 

 indicate the presence of the ooecium there. The type of the genus Escharella 

 is E. immersa, Fleming (^■= Membranlpora PeacMi, Johnston).
