Rare, but extending over all the areas. As a rule quite typical, the best 

 specimens at Station 30. At Station 23 the type is long, at Station 10, in addi- 

 tion to tvpical forms, a thick-walled, coarsely punctate form occurs.

Stations 8, 11, 17, 19, 23, 26, 27, 31. 30 (-fK. I., D.). 



Occurs in all three areas, but in all sparingly, and not south of Station 30. 

 The spinous development is rather poor and as a rule rarely exceeding three 

 spines, situated at equal spaces at the aboral edge. At Station 8 the specimens 

 are two-spined, and also at Station 23, wliere the spines are very long. At 

 Station 36 the spines are long and the surface of the test shows fine striation. 



L. sfaphylharia does not appear to be more than a spinous form of several 

 closely-allied Lagenae, viz., laevigata, niargiiiata and (piadricostulata. All the 

 specimens might be so described.

Stations 0, 8, 10, 11, 27, 47 (+R. d. J.). 



Very sparingly distributed and. with the exception of two Stations, confined 

 to the N.Z. area, where it is frec^uent and very typical, especially at Statioir 6. 

 The Antarctic specimens are smaller, less distinctive and very thin walled.
