HENRY SIDEBOTTOM ON LAGENAE OF THE SOUTH-WEST PACIFIC. 423 



pines at the base, although one cannot be certain if they are 

 intended to be on the edge of the oval wing surrounding the base. 

 I should have taken them to be on the edge but that all the 

 specimens in these gatherings show the spines running in a line 

 from one side to the other through the centre of the enclosed 

 space. It is obvious, I think, that the specimens are the same 

 as the one figured by Brady. Upon examination the base of the 

 test turns out to be very complex. There aie two large specimens 

 in this set of gatherings, one of which is in fine condition ; and 

 after comparing these with othei-s from a different set of soundings, 

 it is possible to come to a fairly accurate conclusion as to the 

 nature of the complex base. As stated before, the spinous ridge 

 runs from side to side through the centre. There appears to be 

 a small, oval ridge placed centrally, as shown in the drawing, 

 fig. 266, and from this a series of closely set plates, standing on 

 edge, radiates all round as far as the outer oval wing. The 

 spaces between the plates are nearly always filled with granular 

 shell-growth. A few small doubtful examples also occur. 

 Locality : Nos. 9, 17. 



Lagena fimbriata Brady var. nov. occlusa (PI. 20, figs. 27, 28). 



There are numerous examples of this elongate variety, some 

 of which are much more compressed than the one figured, while 

 others are broader as compared w^ith their length. The entoso- 

 lenian tube is long and has a coil in it near the orifice. The 

 opening at the base is often nearly closed. The aboral wing is 

 semi-opaque and wrinkled, but the opaqueness may be due to the 

 granular shell-growth, or debris, with which the enclosed space 

 is blocked. I cannot be certain if this basal compressed wing 

 is traversed by tubuli. The orifice appears to be small and 

 circular. Locality : Occurs at many stations, chiefly Nos. 1, 6, 

 13, 18, 28, 32. 



PI. 20, fig. 28. Of this short form, which I think may be 

 taken as a variation of the above, there are only three or four 

 examples. Locality : Uncertain. 



Lagena fimbriata Brady (?) (PI. 21, fig. 17). 



The body of the test is nearly circular in outline and com- 

 pressed. The long neck is supported on either side by a wing.
