PORAMINIFEEA OF THE KEKIMBA AECHIPELAGO. 611 



We think there can be very little doubt as to the Ehizopodal nature of the frag- 

 ments, their general appearance being very distinctive. Moreover, the branching of the 

 tube may be ctnisidered as evidence of their protozoan as opposed to an annelid origin. 

 The interior of the tube is smooth, but there is no trace of any chitinous lining. 

 We have found identical, but much larger, fragments growing in the interstices of 

 the at present somewhat controversial organism named Ramulina herdmani by Dakin 

 (D. 1906, FC. p. 226, pi. — , figs. 1-6), and these leave no doubt whatever as to its 

 Ehizopodal nature, though throwing little or no further light on its affinities. 



Brady's genus Aschemonella appears to be the most likely attribution for these 

 fragments^ but, in view of the fact that the records for the genus are all from deep 

 water ranging between 390 and 2900 fms., nothing more definite can be decided in the 

 absence of perfect specimens.

Several specimens growing attached to an oyster-shell from Stn. % X. The majority 

 of them were simple tubes, the remainder furcating irregularly.

Was only observed at five Stns., but probably occurs adherent to coarse material all 

 over the area. A few large shells which vre received in spirit, locality unmentioned, 

 were covered with an exceptionally dense growth of this organism.
