598 HENRY SIDEBOTTOM ON LAGENAE OF THE SOUTH-WEST PACIFIC. 



Lagena pacifica sp. nov. (PI. 16, fig. 29). 



The test is ovate, elongate, and has a long, delicate neck. The 

 surface, under a high power, appears to be marked all over with 

 irregular depressions, and shines to a certain extent. The w-all 

 is compound, but I am at present unable to ascertain its exact 

 nature. Yery rare. Locality : Nos. 1, 22, and a few other 

 stations. 



Lagena pannosa Millett. 



Lagena pannosa Millett, 1901, p. 11, pi. 1, figs. 12-14. 



There is only one example, and it is of the variety L. pannosa 

 var., fig. 14. Mr. Millett states that in this variety "the dis- 

 integration is more irregular and the zones are not produced." 

 The test is more globular than the one figured by Mr. Millett. 

 Locality : Exact locality uncertain. 



Lagena spumosa Millett var. (PI. 16, fig. 30). 



Lagena spumosa Millett, 1901, p. 9, pi. 1, fig. 9. 



Mr. Millett considers this to be a variety of his L. sjmniosa^ 

 It differs from the type in not having the " bird's-clawlike " 

 process at the oral end, but simply a short, straight, transparent 

 blunted point to the test, which is flattened at the base. The 

 .-shell-wall is compound. The test is much more brittle than one 

 would expect from its appearance. Tjocality : It occurs rarely at 

 twelve stations, but chiefly at Ko. 30. 



Lagena chasteri Millett (PI. 16, fig. 31). 



Lagena chasteri Millett, 1901, p. 11, pi. 1, fig. 11. 



This occurs sparsely at a few stations. Some of the smaller 

 -examples are more slender than the one figured, and in these the 

 neck and upper portion of the test are inclined to be bent a 

 little to one side. The curious little " stopper " at the orifice is 

 sometimes diflicult to make out ; Mr. Millett tells me it is 

 characteristic of the species. Locality : Exact localities uncertain. 



Lagena chasteri Millett, var. (?) (PI. 16, figs. 32-34). 



These appear to me to be variations of the type. Some, at any 

 rate, show the " stopper" at the orifice. The test is very finely 

 pitted all over, and in certain conditions minute pores can be seen 

 quite plainly, under a magnification of one hundred diameters.
