Miscellaneous. 397 



tory of Quadrupeds' (1781) and in Governor Phillips's ' Voyage to 

 Botany Bay ' (1789) have received Latin names, thus forestalling 

 those in Shaw's ' General Zoology ' (1800-4), which have hitherto 

 been looked upon as the first Latin binomial names of these 

 species. 



On a cursory inspection I have noticed the following changes in 

 nomenclature to be necessary : — 



The species hitherto knotvn as must stand as 



Dolichotis patachonica (Shaiv) D. magellanica (Ken-). 



Sciurus Plantam, Ljung, S. badging, Kerr. 

 Xerus narnaquensis (Licht.) 



(" X. setosus, Forst." auct.) X. capensis (Kerr). 



Petaurus taguanoides, Desm., P. volans (Kerr). 



Phalangista vulpina (Shaw) P. vulpecula (Kerr). 



But fortunately, in a large number of cases, it will only be neces- 

 sary to accredit the old specific name to Kerr, later authors having 

 used the same name. 



In this latter class the following may be instanced : — 



M. Lutra canadensis, Kerr, = L. canadensis, Turt. 



M. zibellina americana, = Martes americana (Turt.). 



Ursus indicus, = Mellivora indica (Shaw). 



Hystrix mexicana, = Sphingurus mexicanus (Shaw). 



Mus messorius, = M. messorius, Shaiv. 



Didelphis virginianus, = D. virginianus, Shaiv. 



The British-Museum copy has evidently never been referred to, 

 the leaves being uncut throughout. 



The full title is " The Animal Kingdom, or Zoological System of 

 the celebrated Sir Charles Linnaeus. Class I. Mammalia, containin"- 

 a complete systematic description, arrangement, and nomenclature 

 of all the known species and varieties of the Mammalia, or animals 

 which give suck to their young, being a translation of that part of 

 the Systema .Naturae, as lately published, with great improvements 

 by Professor Gmelin of Goettingen. Together with numerous addi- 

 tions from more recent zoological writers, and illustrated with copper- 

 plates : by Robert Kerr, P.R. & A.SS.E., Member of the Royal 

 College of Surgeons, and of the Royal Physical Society, and Surgeon 

 to the Orphan Hospital of Edinburgh. London : 1792." 



I have thought it well to draw the attention of zoologists to this 

 work, as the sooner the oversight of a book of this kind is noticed 

 the better it is for the correctness of zoological nomenclature*. 



On the Structure of the Cephalic Ganglia of Insects. 

 By M. N. Wagner. 



It is well known that the two pairs of ganglia lodged in the head 

 of an insect differ considerably with regard to their physiological 

 functions. Formerly the part of an apparatus of coordination was 

 ascribed to the suboesophageal ganglion ; but several naturalists have
