Pyrgoma cretacea, H. Woodw.—In my first Report on Fossil Crustacea (Brit. Assoc. for the Advancement of Science, 1865, Reports, p. 321), I called attention to the occurrence, in the Upper Chalk of Norwich, of a sessile Cirripede belonging to the genus Pyrgoma. This unique example—for which I proposed the name of pyrgoma cretacea—was discovered by Mr. T. G. Bayfield, of Norwich, who forwarded the specimen to the British Museum where I had the good fortune to detect its character. As no other specimen of this new species has been met with, I have thought it advisable (although only an imperfect example) to place it on record in the hope that better ones may be found. It is represented in the accompanying Plate XIV., Figs. 1 and 2, of the natural size.
