British species of the genus Lagena. 
me the opportunity of verifying the present existence of the same 
forms on various parts of the British coasts. 
The earliest notice of any forms of Lagence which has come 
under my observation is in the ^Testacea Minuta Rariora^ of 
Mr. Walker^ published in 1784. He describes a number of Bri- 
tish species which he arranged amongst the Serpula, distinguish- 
ing them however by the subgeneric name of Lagena. 
In 1789 and 1791 Soldani figured some forms from the Adri- 
atic, in his ^ Testaceographise et Zoophytographise, parvse et mi- 
croscopicse/ &c., tab. 120. 
In 1803 Montagu republished Walker^s species in his ^ Tes- 
tacea Britannica/ adding a few others which had been discovered 
by Mr. Boys of Sandwich. Montagu followed Walker’s plan of 
arranging them with the Serpuloi, making them a part of his 
genus Vermiculum. 
In 1808 Denys de Montfort introduced the genus into his 
' Conchyliologie Systematique/ under the French and Latin ge- 
neric names of Lagenules and Lagenula, classing them amongst 
his Univalves cloisonnees, or group of Nautili, in which group, 
like his predecessors Soldani, Plancus, and Fichtel and Moll, he 
comprehended all the Foraminifera. 
In 1815 Dr. Fleming separated them from the Serpula, and, 
carrying out the intimation of Walker, gave them the rank of a 
genus in the article Conchology, published in the ^ Edin. Ency.’ 
vol. vii. p. 68. He applied to them the generic name of Lagena, 
very properly adopting the subgeneric term given to them by 
Walker, to whom certainly belonged the credit of pointing out 
the necessity for distinguishing them from any existing genus. 
It is to be regretted that Dr. Fleming subsequently abandoned 
this name for that of De Montfort. 
In 1826 M. Dessalines D’Orbigny published his classification 
of the Cephalopoda* : in this arrangement he followed the views 
of preceding naturalists, regarding most of the Foraminifera as 
cephalopodous ; but he separated three of the genera, Lagenula, 
Discolites and Chelibs; having anticipated Ehrenberg’s subse- 
quent discovery of the zoophytic character of all the Foraminifera, 
by determining that these three must be arranged with the true 
Polypifera. 
At the same time Dr. Fleming, in his work on ^ British Ani- 
mals,’ was arranging the genus ‘^Lagenula” amongst the Fora- 
minifera, regarding them as Cephalopoda, but with evident mis- 
givings as to his correctness ; for he observes, The place of this 
genus is far from being satisfactorily determined, and the mi-
