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



Lagena Hertwigiana Brady (PI. 15, fig. 33). 



Lagena Hertwigiana Brady, 1881, Quart. Journ. Micr. Sci., vol. 21, 



N.S., p. 62. 

 Lagena Hertwigiana Brady, 1884, p. 470, pi. 58, fig. 36. 



The figure in my copy of the Challenger Report, pi. 58, 

 fig. 36, does not show the reticulation referred to in the description 

 of the species in the text, p. 470. In the three or four specimens 

 found in these soundings, the surface is roughened and the 

 perforations show very plainly. Locality : Uncertain, with the 

 exception of No. 43. 



Lagena Hertwigiana Brady var. undulata Sidebottom. 



Lagena Hertwigiana Brady var. undulata Sidebottom, 1912, 

 Journ. Q. M. C, p. 397, pi. 16, figs. 26-28. 



Many examples occur. Locality : Nearly all the stations, but 

 chiefly Nos. 2, 7, 10, 17, 24, 34, 43. 



Lagena pacifica Sidebottom. 



Xagena pacijica Sidebottom, 1912, Journ. Q. M. C, p. 398, pi. 16 f 

 fig. 29. 



Only two or three specimens found. Locality : Uncertain. 



Lagena splendida sp. nov. (PI. 16, fig?. 1-3). 



I am quite at a loss how to describe this exquisite Lagena. 

 -adequately, and I am unable to draw it owing to the complexity 

 of its decoration, which is exceedingly minute. The test glistens 

 and most probably it has been apiculate. The neck is fractured. 

 There is a second specimen which I think is the same, but there 

 is a slight difference in its appearance which I am unable to 

 explain. It is apiculate. Locality : Uncertain. 



Note. Not being able to get a satisfactory definition with my 

 microscope, I submitted the test to Mr. Earland for examination, 

 who had better means of lighting up the test than I had. His 

 observations were made with the assistance of a Zeiss vertical 

 illuminator and daylight instead of artificial light. He writes as 

 follows :
