 hut may best be compared to the head of a short-billed ac^\iatic bird. -We have

Occurs only at the three deep-water Stations, and at one other. With one 

 exception all ai'e of the compressed form figured by Brady, and having a slight 

 median keel round the base. This keel, in the specimen from Station 17, is 

 bifid in the centre of the base, and then curves up slightly at diverging angles. 

 At Station 18 a slightly hispid specimen, and at this Station the only non-com- 

 pressed specimen, which is much longer and narrower than Brady's figure.

Generally distribivted but never very abundant. Usually of a long-necked 

 tvpe. At Station 38 the species attains a gigantic size with coiresponding develop- 

 ment of markings. It becomes obvious that the ribs are solid structures with 

 cells sunk in them at regular intervals throughout their length, the surface being 

 covered with a very delicate outer shell. The structure bears considerable 

 resemblance to that described in our new species, L. scotfii. At Station 6 an 

 individual was found in which the raised costae were broad and flat and decorated 

 witli a double row of pores. At the same Station a Lagena was found with 

 a glassv fusiform bodv, showing bands of denser shell-substances, each band 

 consisting of two parallel rows of dots ; it seems probable that this may be an 

 abnormal L. striato-punctata, in which the costae have never been developed.
