426 HENRY SIDEBOTTOM ON LAGENAE OF THE SOUTH-WEST PACIP'IC. 



tubular spines, each of which has its orifice minutely phialine. 

 Kunning round the edge of the test are three or four rows of the 

 spines, which are sometimes connected so as to form a ridge. 

 The orifices of the spines show quite distinctly under a magnifica- 

 tion of seventy-five diameters. The test when fresh is semi- 

 transparent, but most of the specimens are opaque and roughened 

 by granular shell-growth, which fills up the spaces between the 

 tubular spines. There are twenty on the slide, one or two of 

 which are round in section, or nearly so. This form may be 

 related to L. hispida, which, though typically round in section, 

 occurs also in the compressed condition, but the nature of the 

 spines is distinctly different. Locality : Eleven found at No. 1, 

 two at No. 18, three at No. 30, and odd ones at a few other 

 stations. 



Lagena elcockiana Millett (PI. 21, fig. 9). 



Lagena elcockiana Millett, 1901, p. 621, pi. 14, figs. 5, 6. 



There were twelve specimens on the slide, but there are only 

 two now, owing to an unfortunate accident. They were all 

 similar to the one figured. Mr. Millett states that it is rare in 

 the Malay Archipelago and only found at a few stations in 

 Area 2. Locality : One found at No. 18, ten at No. 19, and one 

 at No. 20. 



Lagena soleaformis sp. nov. (PI. 21, fig. 10). 



This is a difficult Lagena to describe. Taking as the front of 

 the test that side which shows the orifice of the attached, ento- 

 solenian tube, we are reminded of a horse-shoe. The carina 

 is slightly convex on the front and concave at the back. The 

 central portion (the body of the test) is flattened, and slopes 

 backwards at the base, but the back is highly convex and pro- 

 duced at the base as a curved flange. Eight found. Tjocality : 

 8ix at No. 19, one at No. 20, and one at No. 21. 



Lagena galeaformis sp. nov. (PI. 21, figs. 11, 12). 



Test nearly square in section. It is carinate at the angles, and 

 broader at the base than at the orifice, which is square. A
