General characters.—Shell one-chambered, free, oval, oblong, or fusiform, and subject 
1 We append to the generic name Lagena, and to a number of the specific forms, the initials W. & J. 
(Walker and Jacob), believing this to be the nearest approach to correctness we can make, though some 
authors have, with almost equal reason, assigned the same species to the authority of Walker and Boys, and 
others to Walker. The ‘Testacea Minuta Rariora’ is stated on its title-page to relate to “minute and 
rare shells lately discovered in the sand of the sea-shore, near Sandwich, by William Boys, F.S.A., con- 
siderably augmented, and all their figures drawn by. George Walker,” the latter of whom is spoken of in the 
same page as the author; and his name also appears alone in the dedication. Prof. Williamson, in 
his ‘Monograph,’ has given his reasons why the species may be regarded as Walker's; and in the 
‘Annals Nat. Hist.’ for November, 1859, Mr. Jacod’s title to their authorship is shown. 
We have, however, in our possession a copy of the work, which has evidently been the property of a 
naturalist, having the following note written on the fly-leaf, in ink apparently nearly as old as the book 
itself—<“ the scientific descriptions in this work were written by Dr. Solander.” 
The figures from the ‘Testacea Minuta’ were reprinted and further augmented in Kanmacher's 
edition of Adams’s ‘Essays on the Microscope’ (1789), and the original work is therein stated to have 
been written by Mr. Walker and Mr. Boys, assisted by Edward Jacob, Esq., F.S.A. 
We know that Dr. Solander wrote the scientific descriptions of Ellis’s work on the ‘Zoophytes,’ 
and, singularly enough, Mr. Ellis’s name appears in connection with some allied microscopical organisms 
on the following page in the ‘ Hssays,’ a fact which suggests associations increasing the probability of the 
manuscript note alluded to. 
If Mr. Boys collected, Mr. Walker augmented and figured, Mr. Jacob assisted, Dr. Solander described, 
and Mr. Kanmacher further elaborated, added to, and republished, it is not easy to decide whose initials 
should be appended to such of their specific names as take precedence; at least, we see no reason to change 
the practice we bave hitherto adopted in assigning them to “ Walker and Jacob.”
