162 FOURTH REPORT — 1834. 



The same year Lesson published his Manuel de Mammalogie : 

 his arrangement, however, is the same as that of Cuvier. In 

 1829, appeared the 2nd edition of the R^gne Aniynal, in which 

 the Marsiipialia are considered as a distinct order ; in all other 

 respects the arrangement is the same as that of the first. The 

 same j'^ear Fischer published his Synopsis 3Inmmalium. His 

 orders approach more in character to those of Linnaeus : he 

 adopts, however, two more than that author : one, C/ieiroj)teray 

 placed between the Primates and Ferce ; the other, which he 

 terms Besticc, and which includes the Insectivora and Marsiipi- 

 alia of Cuvier, following the order last mentioned. Also in 

 1829, appeared a valuable treatise on the Mammalia by Fred. 

 Cuvier, in the 59th volume of the Diet, des Sci. Nat. His 

 arrangement differs in one respect from that of all his prede- 

 cessors, in as much as he has thrown together in one order the 

 first two families of the Carnassiers oi the R^gne Anim. and the 

 Insectivorous Marsupialia, while of the Frugivorons Marsupi- 

 alia he has made a separate order. He has also made distinct 

 orders of the Amphibia and Monotremata. 



In 1830, Wagler published his NatUrliches System del' Ani- 

 phibien, to Avhich he has prefixed a classification of Mammalia 

 as well as oiAves. His orders in the former of these classes, 

 amounting to eighteen, are miich more numerous than those of 

 any other author. It is hardly necessary to specify them, as few, 

 I conceive, will be disposed to adopt them all as primary divisions. 

 They more properly deserve the name of families. Wagler con- 

 siders ^\e Monotremata as a distinctclass, to whichhe gives the 

 name of Gryphi. It maybe observed, that he also includes in it 

 the fossil Ichthyosauri and Plesiosavri, as well as the Ornitho- 

 cephalus of Sommerring*. 



In 1831, Charles Lucien Bonaparte published an arrangement 

 of the Vertebrata\ differing in some respects from that of his pre- 

 decessors. T\\Q Mammalia are primarily divided into the two sub- 

 classes of Quadrujjeda and Bipeda, the latter being intended to 

 receive the Cetaceous animals. The Quadrupeda are again divided 

 into the two sections of Unguiculata and Ungulata. His 

 orders resemble those of Fischer, excepting that he isolates the 

 Marsujnalia, referring the Insectivora (with which they are 

 associated by this last author) to the order Ferae. He also 



* Mr. MacLeayhas suggested in his Hora Enlomologicte, p. 267, that possibly 

 the OrnUhoceplialus may have been the connecting link between Mammalia and 

 Birds.
