376 HENRY SIDEBOTTOM ON LAGENAE OF THE SOUTH-WEST PACIFICV 



me. The localities and depths are copied from Mr. Thornhill's 

 book of reference. 



It was his intention to arrange all his Lagenae upon a fresh 

 system, using only a very few specific names and introducing all 

 the rest as variations. Among his papers are a couple of pages 

 of manuscript, showing he was evidently commencing to put his 

 ideas into order. The following passages occur : " Of course all 

 forms are related to one another, and run into one another, but 

 there is only one Lagena in many shapes and forms, just as there 

 is only one House, but many forms and shapes of houses. For 

 many reasons, it may perhaps be proved eventually that the shape 

 of the test actually depends on some recognisable fact." Again : 

 ** Whether or not the depth at which these Lagenae were living 

 has anything to do with it or not, one is struck by the great 

 numerical superiority of the flattened species to the typically 

 globular, and the comparative rarity of tests without striations^ 

 carinations or ornament of some sort." 



I am greatly indebted to my friend Mr. Millett for his valu- 

 able advice, his unfailing courtesy and for entrusting to me the 

 section Lagena of his monograph of the Foraminifera, into which 

 he has copied drawings of all the known species. 



My thanks are also due to Prof. Hickson, of the Victoria 

 University, Manchester, for his kind assistance in selecting suit- 

 able names for many of the new forms. 



No doubt my work is open to criticism, but with all its short- 

 comings I trust it will be acceptable to my co-workers, and will 

 help to extend the interest in this particular genus of the 

 Foraminifera.
