In the transfusion from one language to another, I\ r. 
Dillwyn is often so entirely mistaken, as to destroy all sje- 
cific identity. Thus, in the character of Solen Ensis, canine 
altero bideufato, is rendered “hinge with a double toothin 
each valve.” In Solen amethystus, cardine altero bident do, 
is translated, “hinge with two teetli in each valve.” In 
Chiton Gigas, vulva prime crenata , postrema dentata , meilis 
emarginatis, is rendered, “ the first valve crenate, the list 
toothed, and the intermediate ones entire.” A.-* 1 c 
both from Mr. D. and Mr. Wood, in their interpretation of 
the character in Solen minimus, eardinibu't lateralibius, bU 
dentatis, altcrius bijido, “ hinge lateral, with two teeth, one 
of which is bifid,” rather supposing the meaning to he, that 
there is a bifid tooth in one valve only. 
Mr. Dillwyn s work offering nothing more thr ^ colla¬ 
tion of different authorities, arranged upon his sole judge¬ 
ment, must claim a credit in proportion to the diligence and 
the fidelity with which these powers have been exercised. 
With means and facilities which can fall to the lot of very 
few writers upon natural history, and without the possession 
of which, this compiler has condemned all others to igno¬ 
rant obscurity, we were something surprised at his neglect 
of the fine work on American conchology, by Mr. Jay, in 
the Philadelphia Encyclopaedia; the beautiful plates of 
Perry; and even the latter volumes of the Linnean So¬ 
ciety. 
Of the celebrated manuscripts left by Dr. Solander, we 
learn little more than what we have long known from the 
Portland and Calonnian Catalogues. 
We will likewise venture to remark, that the diligence 
was net well awakened, when it referred to Listers plates 
667- f. 11, and 670. f. 16, both for Cyprseu cinerea, and the 
young of C. Vanelli; the plate 825. f.45, for Voluta rustica, 
and also for V. Tringa; the plate 852. f. 8, for Strombus 
sulcatus, and again for Str. vittatus; the plate 1012. f. 76,
