XXVIII. On Clavagella. By W. J. Broverip, Esq., Vice-President of the Geological 
and Zoological Societies, F.R.S., L.S., &c. 
Communicated October 14, 1834. 
IN the fifth volume of the ‘ Histoire Naturelle des Animaux sans Vertébres,’ published 
in 1818, Lamarck established the genus Clavagella, placing it with good judgment 
between Aspergillum, Lam., and Fistulana, Brug., and recorded four species, all fossil, 
referring at the same time to the ‘ Annales du Muséum,’ where he had described and 
figured the first of them under the name of Fistulana echinata. The following is La- 
marck’s definition of the genus. 
‘« Vagina tubulosa, testacea, anticé attenuata et aperta, postice in clavam ovatam, sub- 
compressam, tubulis spiniformibus echinatam terminata: clavd hinc valvam detectam in 
pariete fixam prodiente ; altera in tubo libera.” 
Mr. George Sowerby, whose attention had been attracted to a recent specimen in the 
British Museum, which he took for an Aspergillum, inclosed in a mass of stone, re- 
quested Mr. Children to allow a close inspection ; and that gentleman, with his usual 
liberality and readiness to apply that part of the national collection committed more 
immediately to his care to the advancement of knowledge, its true and legitimate use, 
permitted some of the earthy part to be scraped away, when Clav. aperta, the first re- 
corded recent species, was seen as it is described and figured in Mr. Sowerby’s ‘ Genera 
of recent and fossil Shells.’ 
Mr. Sowerby’s definition is nearly the same as Lamarck’s. 
Upon the return of Mr. Samuel Stutchbury from his voyage to some of the islands 
of the Australian and Polynesian groups, Mr. George Sowerby, in his appendix to the 
catalogue of subjects of natural history brought home by Mr. Stutchbury, described 
and figured, in the year 1827, a second species under the name of Clav. Australis. 
Three specimens were obtained with great difficulty by Mr. Stutchbury, who discovered 
them at North Harbour, Port Jackson, in a siliceous grit, like that of the coal measures, 
just beneath low-water mark, by their ejecting the water from the opening of their tubes 
with considerable force. The specimen figured by Mr. Sowerby is in the British Mu- 
seum, and another is in Mr. Norris’s collection at Manchester. 
Soon after the publication of the latter species, Isaac Lyon Goldsmid, Esq., became 
possessed of a mass of coral (Astreopora, Blainv.), part of a collection which he had 
purchased at Aix la Chapelle. In 1829 Mr. Henry Stutchbury, to whom Mr. Goldsmid 
assigned the task of arranging this collection, observed an aperture which he concluded
