cervicorn brancli. Attached to a piece of molluscan shell.

 4. Gr — Chapmau Collection. — This example exhibits an initial 

 Poly morphine structure on the plan of P.fusiformis, Homer, 

 but differs from the usual forms of Eamuline commencements 

 in having outgrowths at both ends of the Polymorphine 

 portion. At one end is a short cervicorn outgrowth, at the 

 points of which the apertures are clearly seen ; at the otber 

 end are the rudiments of two tubes, one springing forth 

 laterally. This specimen is incomplete, and what was 

 possibly the most interesting portion has been removed by 

 the fracture of the Frondicularia to which it was attached.

5. J — Chapman Collection. — The initial Polymorphine series, 



referable to P.fusiformis, Eomer, is succeeded by an out- 

 growth at each end. One is definitely cervicorn; and the 

 other (broken) was probably of the same character. Test 

 attached to a fragment of molluscan shell. Gault ; Folke- 

 stone. — Fig. 49. 



6. Chapman Collection. Journ. E. Micr. Soc. 1896, p. 584, 



pi. xiii. fig. 10. — A Polymorphine commencement and a single 

 process, widening rapidly, subtriaugular in form, with an 

 aperture at each of the anterior angles. Grault ; Folke- 

 stone. — Fig. 50. 



7. Chapman Collection, ioc. c?Y. fig. 11. — A dichotomous form, 



attached. The initial Polymorphine chambers (obscured by 

 fracture) produce two divergent, lumpy, apical tubes ; one 

 having a doubly dichotomous, blunt, branching termination ; 

 the other ends in a swollen, dichotomous, and, as it were, 

 stunted branch. Grault ; Folkestone. — Fig. 51.
