Corals dredged by H.M.S. ' Challenger. 3 557 



placed in the calicle, the free vertical margins of the primary and 

 secondary septa extending above it for a considerable height. 



Extreme breadth of the calicle 2*45 centims., extreme height 1-1 

 centim. 



The coral was obtained in lat. 42° 10' N., long. 63° 39' W. s from 

 1250 fathoms off the coast of Nova Scotia. The single specimen as yet 

 obtained is evidently abnormal in its arrangement in fives. This 

 arrangement in fives is perfect. There are exactly 40 septa — 10 primary 

 and secondary in dimensions, 10 tertiary, and 20 quaternary. 



Cyathohelia axillaris. 



A single specimen of this species, broken but quite fresh, was obtained 

 from 825 fathoms, in lat. 0°45' S., long. 120° 59' E. This very peculiar 

 form was hitherto known only from Japan. It is quite a new genus 

 amongst deep-sea corals. 



Cryptohelia pudica (?). 



Of Cryptohelia Piercii, Pourtales only obtained very small and badly 

 developed specimens. A large series of specimens of this genus has 

 been dredged by us. They show great variation ; and, some being evi- 

 dently identical with C. Piercii (Pourt.), others seem to show that this 

 species is merely a dwarfed form of Cryptohelia pudica of Milne-Edwards 

 and Haime, from which our best-developed specimens are apparently 

 indistinguishable. Eurther, as has already been pointed out by Pour- 

 tales, the genus Endohelia of Milne-Edwards and Haime* appears 

 indistinguishable from the genus Cryptohelia. We dredged specimens of 

 an undoubted Cryptohelia, apparently of the same species as our other 

 deep-sea specimens, off Japan in 775 fathoms, in the living condition. 

 The genus Cryptohelia appears to be a characteristic deep-sea one, with a 

 remarkably wide range, as with most other deep-sea forms. We have 

 obtained it in the neighbourhood of the Canary Islands and off: the 

 Danish West Indies in the Atlantic, whilst Pourtales obtained it from 

 off Bahia, off Bahia Honda, and off Sombrero, D. W. I. We further 

 obtained it near the Kermadec Islands in the South-west Pacific and 

 off the coast of Japan. M.-Edwards's original specimen was from New 

 Guinea, and therefore probably not from deep water. The coral was, 

 however, not met with by the * Porcupine ' in the Northern Atlantic. 



Bendrophyllia ramea. 



Occurs with Corallium rubrum at the Cape-Verd Islands in from 100 

 to 120 fathoms just as it occurs with Corallium in the Mediterranean. 

 It occurs also in 100 fathoms off Setubal in Portugal, but there without 

 Corallium f .
