SCHIZOPORELLA UNICORNIS (Johnston). B., W. 



I have sliown elsewhere that the genus EscJiarina must be used with 

 E. vulgaris as the type. S. linearis may stand as the type species of ScJiizo- 

 porella, if that genus, contrary to strict rule, is to be maintained ; but some 

 of the species here included are scarcely congeneric, and will probably find 

 another place when the work of Dr. Levinsen is published. 



This species is a common one between tide-marks and down to 15-20 

 fathoms.

Large patches encrusting coal dredged near the coaling ship at Funchal. 



SCHIZOPOEELLA AURIGULATA (Hassall). H., W. 



Specimens received from Prof. Heller as his Lepralia spongites are what 

 has been known as S. auriculata viir. ochracea, Hincks (pi. xxix. fig. 7) with 

 spatulate avicularia mingled with those of ordinary form. 



The species is not rare at Madeira in shallow water.

Senhor De Noronha has sent to me'the variety divergens agreeing closely 

 with Guernsey specimens, from Porto Santo. 



Schizoporella armata, Hincks. H., W. (PI. 40. figs. 5, 6.) 



I have not seen Madeiran specimens ; but I figure an Algerian specimen, 

 which Dr Levinsen kindly gave me, for comparison with S. hiaperta var. 

 divergens.

Schizoporella Noronhat, n. sp. (PI*. 41. fig. 1.) 



The zooeeia are broader than long, widest in the middle, contracted behind 

 and before, and much so in the position of the oral opening ; oral aperture
