HENRY SIDEBOTTOM ON LAGENAE OF THE SOUTH-WEST PACIFIC. 199 



Lagena auriculata Brady var. nov. caudata (PI. 18, figs. 2, 3). 



Test compressed, the lower part of the body faintly striated. 

 A single long spine, probably always bent more or less to one 

 side, projects at the base. Orifice situated at the end of a long 

 neck. In fig. 2 the basal spine is partly broken off. 



The faint striation seems to indicate an affinity with L. auricu- 

 lata var. costata Brady, but in order to avoid giving subvarietal 

 names, I have treated it as a variation of L. auriculata. 

 Locality : No. 2. 



Lagena auriculata Brady var. nov. circunicincta (PI. 18, fig. 4). 



Test compressed, subcarinate, except at the lower edge and 

 base, where the keel is well developed. A few costae run across 

 each face of the test. Orifice oval. Entosolenian tube long and 

 curved. Four specimens occur. There are six tests on the 

 square, but two do not belong to the same variety. Locality .- 

 No. 43, and one of the following stations : Nos. 38, 42, 44, but 

 which one is doubtful. 



Lagena auriculata Brady var. nov. clypeata (PI. 18, fig. 5). 



Test compressed, carinate. Orifice oval. Two raised oval 

 rings (sometimes slightly irregular) on each face of the shell. 

 The loops at the base small. Entosolenian tube long and curved. 

 It is easy to miss noticing the loops. The tests vary a little 

 from one another in outline. The keel is not quite so wide as 

 indicated in the drawing. 



About twenty specimens are arranged on the same square as a 

 number of L. Orbignyana sp. var. Waller iana Wright, for which 

 they may have been temporarily mistaken. Locality : The 

 majority must have been found either at Nos. 42 or 43, or both. 



Lagena auriculata Brady var. Sidebottom (PI. 18, fig. 6). 



Lagena auriculata Brady var. Sidebottom, 1912, Journ. Q. M. C. r 

 p. 421, pi. 20, figs. 15-18. 



Pi. 18, fig. 6 and * pi. 20, fig. 15. I have figured one of 

 average size. There are often a few spines at the base. 

 Locality ; Nos. 4, 23, 24, 38-44. 



A few elongate examples occur. Locality ; Nos. 2. 3-
