occurs also in C. Oweni, Busk of the B.M. Cat., but this may be umbellata, 

 and it may also be seen in C. denticulata of the Crag. 



This species is much like C. umbellata, Del'r., but the lobed or irregular 

 growth of C. Lowei, as described by Busk and Norman, has not been 

 mentioned in umbellata, though it occurs in " Cupularia deformit" Busk, 

 MSS. in the British Museum, which however is closely allied to C. denticu- 

 lata, with the deuticles very wide and solid. The zoaria grow in irregular 

 shapes, often lobed just like C. Lower ; and lieuss in his manuscript after- 

 wards published by Manzoni * speaks of the growth of C. Raidingeri, Rss., 

 being excentric, and from the figures it has the groove mentioned as occurring, 

 in C. Lowei. The " deformis" occurs from the Porcupine Expedition, 

 45 fath. (B.M.) ; Tangier Bay, 35 rath. (B.M.) ; lias el Amourh, 45 fath. 

 (B.M.) ; ('ape Sagras (B.M.), Portugal ; and in my collection from Mer el 

 Kebir, Oran, 50 metres ; I propose to place it under denticulata. 



The polypide of C. Lowei is about double the size of that of C. canariensis. 

 The frontal membrane has no trabecule comparable with that of Selenaria 

 metadata, but there is a minute chitinous curve from the base of the oral 

 aperture to the boundary of the zooecium (PI. 30. fig. 1). We thus know 

 Cupularia with regular, and others with irregular zoaria of the Lowei form, 

 having large frontal pores ; also the same zoarial forms with denticulate 

 lamina.

The Madeira specimens, though in spirit, had evidently been dead some 

 time before preservation, and externally had grains of sand adhering to the 

 membranes, while internally diatoms were numerous, so that satisfactory 

 preparations were impossible. 



The large cells lining the zooecial and other walls are very marked, and the
