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



Lagena semistriata Williamson. 



Lagena striata var. /? semistriata Williamson, 1848, p. 14, pi. 1, 

 figs. 9, 10. 



The great majority are small. Some have the neck bent to 

 one side and the body slightly curved. A few are cylindrical and 

 others have the contour of L. clavata d'Orbigny. Locality : Nos. 

 1, 20-22, 29, 42-44. 



Lagena crenata Parker and Jones var. (PI. 15, fig. 28). 



Lagena crenata Parker and Jones, 1865, p. 420, pi. 18, fig. 4. 



They are not typical, but I think they are best placed under 

 the above heading. The projecting parts at the base run partly 

 towards its centre as blades. The neck is not decorated. A few 

 of the examples are not so slim as the one figured, and have their 

 sides slightly convex. Thirteen specimens occur. I cannot give 

 all the stations at which they are found, but the following may 

 be indicated. Locality : 22, 43. 



Lagena Thornhilli Sidebottom (PI. 15, fig. 29). 



Lagena Thornhilli Sidebottom, 1912, Journ. Q.M.C., p. 390, 

 pi. 15, fig. 26. 



They differ slightly from the one figured at the above reference, 

 for the upper parts of the wings are joined together so as to 

 form a hood, as shown in the figure. In one of the examples 

 the three cavities formed by the hood are blocked with exogenous 

 shell-growth. 



Four examples occur. Locality : 6, 8, 29. 



Lagena stelligera Brady. 



Lagena stelligera Brady, 1881, Quart. Journ. J/icr. Sci., vol. 21, 



N.S., p. 60. 

 Lagena stelligera Brady, 1884, p. 466, pi. 57, figs. 35, 36. 



A good many agree with Brady's Challenger figure, pi. 57, 

 fig. 35, but some are more slender, and several are very 

 minute.
