a rather long obtusely pointed form. The short thick form is by far the commonest, and 

 the obtusely pointed ranks next in point of frequency. '• Plastogamic" or " budding" 

 individuals (or specimens which have passed through this stage, as shown by the de- 

 struction of the apertural end and septa) were observed at Stns. 2, 6, 9, 11, and 12. At 

 none of these Stns. was the species present in such numbers as at Stn. 1, where no 

 associated pairs were observed. Representatives of all three forms were observed 

 among the associated individuals. With one or two exceptions there w-as great 

 disparity in size between the associated shells (see H.-A. 1915, EPF. p. 248, pi. 15. 

 fig. 28, a-f.)

A few individuals at Stn. 7. They form, in their elongated form, a connecting-link 

 between B, marginata and the B. marginata, var. hiserialis of Millett, observed at 

 the same Stn. The chambers in B. j)ulchella are very much more elongate in the long 

 axis of the shell than in typical B. marginata. D'Orbigny's original record was from 

 the west coast of S. America, and the species does not appear to have been recorded 

 elsewhere.

This species is extremely rare, being found at three Stns. only and but a few 

 specimens at each. At Stn. 7 the specimens were small and delicate, with rather a 

 long spine, whereas at Stn. 8 they were thick-shelled and obtuse, similar to the type 

 so abundant in British waters.

A few individuals only. They differ from Millett's figure in the relatively small 

 number of pairs of chambers, having four to five pairs as against eight in his figure.
