422 HENRY SIDEBOTTOM ON LAGENAE OF THE SOUTH-WEST PACIFIC^ 



and are marked as occurring at eight stations, but being mixed 

 with those of another species the stations are uncertain. It occurs 

 at any rate at No. 9. The internal tube is attached. 



PI. 20, fig. 20. There are one or two specimens in which the 

 costae do not become arched, and I take them to be feeble examples 

 of the above. It is possible that they may be a weak form of 

 L. auHculata. var. costata Brady, 1884, pi. 60, fig. 38. 



Lagena auriculata Brady var. costata Brady (Pi. 20, 



figs. 21, 22). 



Lagena auriculata Brady var. costata Brady, 1884, pi. 60, fig. 38.. 



Except that the costae are more numerous and the tubular 

 processes narrower, the specimens agree fairly well with Brady's 

 description of the species. Locality : Uncertain. 



Lagena auriculata Brady var. nov. chq^licata (PI. 20, fig. 23).. 



In this case, instead of there being only two tubular processes 

 at the base of the test, there are four, two on either side of the 

 carina. It might be looked upon as a variety of L. alveolata var. 

 suhstriata Brady, but the basal extensions are more characteristic 

 of L. auriculata. Three found. Locality : Nos. 10, 17. 



Lagena fimbriata Brady (PI. 20, figs. 24-26).

1881, p. 61. 

 Lagena fimbriata Brady, 1884, p. 486, pi. 60, fi.gs. 26-28. 



There is a single fractured specimen similar to the Challenger 

 illustration, pi. 60, fig. 28. Locality : Uncertain. 



PI. 20, figs. 24, 25. These come pretty near to the Challenger 

 example, pi. 60, fig. 27. Most of the specimens are not quite so 

 broad as the one figured. Owing to debris, or shell-growth, 

 clogging the enclosed space at the base, I cannot be quite certain 

 if the walls are travei-sed by tubuli ; at any rate, they are often 

 crinkled. There is no entosolenian tube. Nineteen occur. 

 Locality: Fig. 24, chiefly at Nos. 3, 9. Fig. 25, only three 

 found, No. 28. 



PI. 20, fig. 26. In the Challenger Eeport Brady gives no detailed 

 description of his fig. 26, pi. 60, but his drawing shows a series of
