Not uncommon on shells, stones, and Madracis asperida in 50-70 fathoms. 

 The examples on the coral referred to are commonly associated with 

 Onychocella angulosa, to which species, when seen with the naked eye, it bears 

 a remarkable resemblance {A. AI. N.). Porto Santo in GO fathoms

Some small typical fragments occurred, and also a very large example on 

 stone, differing from all other specimens I have seen in having the openings 

 occupying a less portion of the zooecium than usual, or in other words the 

 covered portion longer than usual. 



Membraniporella nitida (Johnst07l). H., W. 



This species has been recorded both by Hincks and Waters, but I have not 

 myself seen any typical Madeiran nitida, but only the form described below. 



Var. intermedia. (PL 36. tig. 7.) 

 In all respects except the front wall this form agrees with M. nitida ; but 

 whereas in all the varieties of that species seen by me from northern localities 

 the radiating ribs are separated during their length and are only united on the 

 median line, there joining the extremities of those from the opposite side, and 

 thus constituting the longitudinal central rib -, in this var. intermedia the
