610 MESSES. E. HEEON-ALLEN AND A. EAELAND ON THE 



1 Station. 



One unbroken initial portion and a terminal fragment from Stn. 1, built up of sand- 

 grains aad calcareous particles. Most of the records given by Brady are from deep 

 Avater, but the species probably occurs all over the world in moderate depths, as it 

 certainly does round the British Islands.

7 Stations. 



A few specimens only, excepting at Stns. 12 and IX. Some attached to shell-frag- 

 ments, others free, others again which have evidently been attached in their earlier life 

 and have subsequently adopted a free existence. There is the usual range in the method 

 of construction. At Stn. 9, where the specimen was attached to the inner concave 

 surface of a shell, the tube was thin and largely composed of cement. At Stn. 12, 

 where the specimens were attached to the exterior surface of Nullipore algce, the tube 

 was stoutly built, witli large incorporated sand-grains. At Stn. 2 the single specimen 

 was principally built up of sponge-spicules and cement, the spicules projecting in the 

 manner adopted by Hyperammina ramosa Brady. At Stns. 3 and 1 1 the tube was 

 built of fine sand-grains embedded evenly in cement.

1 Station. 



At Stn. 11a few fragments of an organism were obtained, which we think must be 

 attributed to Brady's species. They consist of portions of a branching unseptate tube, 

 built up of sponge-spicules, arranged parallel to the long axis of the tube and covered 

 with an investing layer of sand and cement, the whole forming a somewhat thin-walled 

 organism, in which the central space is large compared to the thickness of the wall of 

 the test. None of the fragments shows an unbroken terminal portion, either oral or 

 aboral. The colour is a very pale brown, but there is no noticeable ferruginous 

 cement.
